Blender (program)

Blender is a free and open-source 3D computer graphics software tool set used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, virtual reality, and, formerly, video games. Blender's features include 3D modelling, UV mapping, texturing, digital drawing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, animation, match moving, rendering, motion graphics, video editing, and compositing.

History

The Dutch animation studio NeoGeo (not related to Neo Geo video game hardware) started to develop Blender as an in-house application, and based on the timestamps for the first source files, January 2, 1994 is considered to be Blender's birthday. Version 1.00 was released in January 1995, with the primary author being company co-owner and software developer Ton Roosendaal. The name ''Blender'' was inspired by a song by the Swiss electronic band Yello, from the album ''Baby'', which NeoGeo used in its showreel. Some design choices and experiences for Blender were carried over from an earlier software application, called Traces, that Roosendaal developed for NeoGeo on the Commodore Amiga platform during the 1987–1991 period.

On January 1, 1998, Blender was released publicly online as SGI freeware. NeoGeo was later dissolved, and its client contracts were taken over by another company. After NeoGeo's dissolution, Ton Roosendaal founded Not a Number Technologies (NaN) in June 1998 to further develop Blender, initially distributing it as shareware until NaN went bankrupt in 2002. This also resulted in the discontinuation of Blender's development.

In May 2002, Roosendaal started the non-profit Blender Foundation, with the first goal to find a way to continue developing and promoting Blender as a community-based open-source project. On July 18, 2002, Roosendaal started the "Free Blender" campaign, a crowdfunding precursor. The campaign aimed at open-sourcing Blender for a one-time payment of €100,000 (US$100,670 at the time), with the money being collected from the community. On September 7, 2002, it was announced that they had collected enough funds and would release the Blender source code. Today, Blender is free and open-source software, largely developed by its community as well as 24 employees employed by the Blender Institute.

The Blender Foundation initially reserved the right to use dual licensing so that, in addition to GPL 2.0-or-later, Blender would have been available also under the "Blender License", which did not require disclosing source code but required payments to the Blender Foundation. However, this option was never exercised and was suspended indefinitely in 2005. Blender is solely available under "GNU GPLv2 or any later" and was not updated to the GPLv3, as "no evident benefits" were seen.

In 2019, with the release of version 2.80, the integrated game engine for making and prototyping video games was removed; Blender's developers recommended that users migrate to more powerful open source game engines such as Godot instead.

Suzanne

In February 2002, it was clear that the company behind Blender, NaN, could not survive and would close its doors in March. Nevertheless, they put out one more release, Blender 2.25. As a sort of Easter egg and last personal tag, the artists and developers decided to add a 3D model of a chimpanzee head (called a "monkey" in the software). It was created by Willem-Paul van Overbruggen (SLiD3), who named it Suzanne after the orangutan in the Kevin Smith film '' Jay and Silent Bob Strike Back''.

Suzanne is Blender's alternative to more common test models such as the Utah Teapot and the Stanford Bunny. A low-polygon model with only 500 faces, Suzanne is included in Blender and often used as a quick and easy way to test materials, animations, rigs, textures, and lighting setups. It is as easily added to a scene as primitives such as a cube or plane.

The largest Blender contest gives out an award called the Suzanne Award.

Release history

The following table lists notable developments during Blender's release history: green indicates the current version, yellow indicates currently supported versions, and red indicates versions that are no longer supported (though many later versions can still be used on modern systems).

As of 2021, official releases of Blender for Microsoft Windows, and Linux, as well as a port for FreeBSD, are available in 64-bit versions. Blender is available for Windows 8.1 and above, and Mac OS X 10.13 and above.

Blender 2.76b was the last supported release for Windows XP and version 2.63 was the last supported release for PowerPC. Blender 2.83 LTS and 2.92 were the last supported versions for Windows 7. In 2013, Blender was released on Android as a demo, but hasn't been updated since.

Features

Modeling

Blender has support for a variety of geometric primitives, including polygon meshes, Bézier curves, NURBS surfaces, metaballs, icospheres, text, and an n-gon modeling system called B-mesh. There is also an advanced polygonal modelling system which can be accessed through an edit mode. It supports features such as extrusion, bevelling, and subdividing.

Modifiers

Modifiers apply non-destructive effects which can be applied upon rendering or exporting, such as subdivision surfaces.

Sculpting

Blender has multi-resolution digital sculpting, which includes dynamic topology, "baking", remeshing, re-symmetrization, and decimation. The latter is used to simplify models for exporting purposes (an example being game assets).

Geometry nodes

Blender has a geometry node system for procedurally and non-destructively creating and manipulating geometry. It was first added to Blender 2.92, which focuses on object scattering and instancing. It takes the form of a modifier, so it can be stacked over other different modifiers. The system uses object attributes, which can be modified and overridden with string inputs. Attributes can include positions, normals and UV maps. All attributes can be viewed in an attribute spreadsheet editor. The Geometry Nodes utility also has the capability of creating primitive meshes. In Blender 3.0, support for creating and modifying curves objects was added to Geometry Nodes. In Blender 3.0, the Geometry Nodes workflow was completely redesigned with fields, in order to make the system more intuitive and work like shader nodes.Archived a

Simulation

Blender can be used to simulate smoke, rain, dust, cloth, fluids, hair, and rigid bodies.

Fluid simulation

The fluid simulator can be used for simulating liquids, like water being poured into a cup. It uses Lattice Boltzmann methods (LBM) to simulate fluids and allows for plenty of adjustment of particles and resolution. The particle physics fluid simulation creates particles that follow the smoothed-particle hydrodynamics method.

Blender has simulation tools for soft-body dynamics, including mesh collision detection, LBM fluid dynamics, smoke simulation, Bullet rigid-body dynamics, an ocean generator with waves, a particle system that includes support for particle-based hair, and real-time control during physics simulation and rendering.

In Blender 2.82, a new fluid simulation system called Mantaflow was added, replacing the old FLIP system. In Blender 2.92, another fluid simulation system called APIC, which builds on Mantaflow, was added. Vortices and more stable calculations are improved from the FLIP system.

Cloth Simulation

Cloth simulation is done by simulating vertices with a rigid body simulation. If done on a 3D mesh, it will produce similar effects as the soft body simulation.

Animation

Blender's keyframed animation capabilities include inverse kinematics, armatures, hooks, curve- and lattice-based deformations, shape keys, non-linear animation, constraints, and vertex weighting. In addition, its Grease Pencil tools allow for 2D animation within a full 3D pipeline.

Rendering

Internal render engine with scanline rendering, indirect lighting, and ambient occlusion that can export in a wide variety of formats; A path tracer render engine called Cycles, which can take advantage of the GPU for rendering. Cycles supports the Open Shading Language since Blender 2.65.

Cycles Hybrid Rendering is possible in Version 2.92 with Optix. Tiles are calculated with GPU in combination with cpu.

EEVEE is a new physically based real-time renderer. It works both as a renderer for final frames, and as the engine driving Blender's real-time viewport for creating assets.

Texturing and shading

Blender allows procedural and node-based textures, as well as texture painting, projective painting, vertex painting, weight painting and dynamic painting.

Post-production

Blender has a node-based compositor within the rendering pipeline, which is accelerated with OpenCL. It also includes a non-linear video editor called the Video Sequence Editor (VSE), with support for effects like Gaussian blur, color grading, fade and wipe transitions, and other video transformations. However, there is no built-in multi-core support for rendering video with the VSE.

Plugins/addons and scripts

Blender supports Python scripting for the creation of custom tools, prototyping, game logic, importing/exporting from other formats, and task automation. This allows for integration with several external render engines through plugins/addons.

File format

Blender features an internal file system that can pack multiple scenes into a single ".blend" file.

* Most of Blender's ".blend" files are forward, backward, and cross-platform compatible with other versions of Blender, with the following exceptions:
** Loading animations stored in post-2.5 files in Blender pre-2.5. This is due to the reworked animation subsystem introduced in Blender 2.5 being inherently incompatible with older versions.
** Loading meshes stored in post 2.63. This is due to the introduction of BMesh, a more versatile mesh format.
** Blender 2.8 ".blend" files are no longer fully backward compatible, causing errors when opened in previous versions.
** Many 3.x ".blend" files are not completely backwards-compatible as well, and may cause errors with previous versions.
* All scenes, objects, materials, textures, sounds, images, and post-production effects for an entire animation can be packaged and stored in a single ".blend" file. Data loaded from external sources, such as images and sounds, can also be stored externally and referenced through either an absolute or relative file path. Likewise, ".blend" files themselves can also be used as libraries of Blender assets.
* Interface configurations are retained in ".blend" files.

A wide variety of import/export scripts that extend Blender capabilities (accessing the object data via an internal API) make it possible to interoperate with other 3D tools.

Blender organizes data as various kinds of "data blocks" (akin to glTF), such as Objects, Meshes, Lamps, Scenes, Materials, Images, and so on. An object in Blender consists of multiple data blocks – for example, what the user would describe as a polygon mesh consists of at least an Object and a Mesh data block, and usually also a Material and many more, linked together. This allows various data blocks to refer to each other. There may be, for example, multiple Objects that refer to the same Mesh, and making subsequent editing of the shared mesh results in shape changes in all Objects using this Mesh. Objects, meshes, materials, textures, etc. can also be linked to other .blend files, which is what allows the use of .blend files as reusable resource libraries.

Import and export

The software supports a variety of 3D file formats for import and export, among them Alembic, 3D Studio (3DS), FBX, DXF, SVG, STL (for 3D printing), UDIM, USD, VRML, WebM, X3D and OBJ.

Deprecated features

Blender Game Engine

The Blender Game Engine was a built-in real-time graphics and logic engine with features such as collision detection, a dynamics engine, and programmable logic. It also allowed the creation of stand-alone, real-time applications ranging from architectural visualization to video games. In April 2018, the engine was removed from the upcoming Blender 2.8 release series, due to updates and revisions to the engine lagging behind other game engines such as the open-source Godot, and Unity. In the 2.8 announcements, the Blender team specifically mentioned the Godot engine as a suitable replacement for migrating Blender Game Engine users.

Blender Internal

Blender Internal, a biased rasterization engine and scanline renderer used in previous versions of Blender, was also removed for the 2.80 release in favor of the new "Eevee" renderer, a realtime physically based renderer.

User interface

Commands

Most of the commands are accessible via hotkeys. There are also comprehensive graphical menus. Numeric buttons can be "dragged" to change their value directly without the need to aim at a particular widget, as well as being set using the keyboard. Both sliders and number buttons can be constrained to various step sizes with modifiers like the and keys. Python expressions can also be typed directly into number entry fields, allowing mathematical expressions to specify values.

Modes

Blender includes many modes for interacting with objects, the two primary ones being ''Object Mode'' and ''Edit Mode'', which are toggled with the key. Object mode is used to manipulate individual objects as a unit, while Edit mode is used to manipulate the actual object data. For example, an Object Mode can be used to move, scale, and rotate entire polygon meshes, and Edit Mode can be used to manipulate the individual vertices of a single mesh. There are also several other modes, such as Vertex Paint, Weight Paint, and Sculpt Mode.

Workspaces

The Blender GUI builds its tiled windowing system on top of one or multiple windows provided by the underlying platform. One platform window (often sized to fill the screen) is divided into sections and subsections that can be of any type of Blender's views or window types. The user can define multiple layouts of such Blender windows, called screens, and switch quickly between them by selecting from a menu or with keyboard shortcuts. Each window type's own GUI elements can be controlled with the same tools that manipulate the 3D view. For example, one can zoom in and out of GUI-buttons using similar controls, one zooms in and out in the 3D viewport. The GUI viewport and screen layout are fully user-customizable. It is possible to set up the interface for specific tasks such as video editing or UV mapping or texturing by hiding features not used for the task.

Rendering engines

Cycles

Cycles is a path-tracing render engine that is designed to be interactive and easy to use, while still supporting many features. It has been included with Blender since 2011, with the release of Blender 2.61. Cycles supports with AVX, AVX2 and AVX-512 extensions, as well as CPU acceleration in modern hardware.

GPU rendering

Cycles supports GPU rendering, which is used to speed up rendering times. There are three GPU rendering modes: CUDA, which is the preferred method for older Nvidia graphics cards; OptiX, which utilizes the hardware ray-tracing capabilities of Nvidia's Turing architecture & Ampere architecture; and OpenCL, which supports rendering on AMD Radeon graphics cards (with added Intel Iris and Xe support in 2.92). The toolkit software associated with these rendering modes does not come within Blender and needs to be separately installed and configured as per their respective source instructions.

Multiple GPUs are also supported, which can be used to create a render farm—having multiple GPUs, however, does not increase the available memory since each GPU can only access its own memory. Since Version 2.90, this limitation of SLI cards is broken with Nvidia's NVlink.

Apple's Metal API got initial implementation in blender 3.1 for Apple computers with M1 chips and AMD graphics cards.

A Benchmark of Blender 3.2 shows great advantages of long supported CUDA against newer API OptiX and brand new HIP for AMD Hardware. Some Improvements in performance will be available for HIP and OptiX in Blender 3.3 and 3.4.

Support for Intel Arc GPUs arrived in Blender 3.3 LTS.

Integrator

The integrator is the core rendering algorithm used for lighting computations. Cycles currently supports a path tracing integrator with direct light sampling. It works well for a variety of lighting setups, but it is not as suitable for caustics and certain other complex lighting situations. Rays are traced from the camera into the scene, bouncing around until they find a light source (a lamp, an object material emitting light, or the world background), or until they are simply terminated based on the number of maximum bounces determined in the light path settings for the renderer. To find lamps and surfaces emitting light, both indirect light sampling (letting the ray follow the surface bidirectional scattering distribution function, or BSDF) and direct light sampling (picking a light source and tracing a ray towards it) are used.

=The two types of integrators

=

# The default path tracing integrator is a "pure" path tracer. This integrator works by sending several light rays that act as photons from the camera out into the scene. These rays will eventually hit either: a light source, an object, or the world background. If these rays hit an object, they will bounce based on the angle of impact, and continue bouncing until a light source has been reached or until a maximum number of bounces, as determined by the user, which will cause it to terminate and result in a black, unlit pixel. Multiple rays are calculated and averaged out for each pixel, a process known as "sampling". This sampling number is set by the user and greatly affects the final image. Lower sampling often results in more noise and has the potential to create "fireflies" (which are uncharacteristically bright pixels), while higher sampling greatly reduces noise, but also increases render times.
# The alternative is a branched path tracing integrator, which works mostly the same way. Branched path tracing splits the light rays at each intersection with an object according to different surface components, and takes all lights into account for shading instead of just one. This added complexity makes computing each ray slower but reduces noise in the render, especially in scenes dominated by direct (one-bounce) lighting.

Open Shading Language

Blender users can create their own nodes using the Open Shading Language (OSL), although it is important to note that this feature is not supported by GPUs.

Materials

Materials define the look of meshes, NURBS curves, and other geometric objects. They consist of three shaders to define the mesh's surface appearance, volume inside, and surface displacement.

=Surface shader

=
The ''surface shader'' defines the light interaction at the surface of the mesh. One or more bidirectional scattering distribution functions, or BSDFs, can specify if incoming light is reflected, refracted into the mesh, or absorbed. The alpha value is one measure of translucency.

=Volume shader

=
When the surface shader does not reflect or absorb light, it enters the volume (light transmission). If no volume shader is specified, it will pass straight through (or be refracted, see refractive index or IOR) to another side of the mesh.

If one is defined, a ''volume shader'' describes the light interaction as it passes through the volume of the mesh. Light may be scattered, absorbed, or even emitted at any point in the volume.

=Displacement shader

=
The shape of the surface may be altered by ''displacement shaders''. In this way, textures can be used to make the mesh surface more detailed.

Depending on the settings, the displacement may be virtual-only modifying the surface normals to give the impression of displacement (also known as bump mapping) – real, or a combination of real displacement with bump mapping.

EEVEE

EEVEE (or Eevee) is a real-time PBR renderer included in Blender from version 2.8. This render engine was given the nickname Eevee, after the Pokémon. The name was later made into the backronym "Extra Easy Virtual Environment Engine" or EEVEE.

Development

Since the opening of the source code, Blender has experienced significant refactoring of the initial codebase and major additions to its feature set.

Improvements include an animation system refresh; a stack-based modifier system; an updated particle system (which can also be used to simulate hair and fur); fluid dynamics; soft-body dynamics; GLSL shaders support in the game engine; advanced UV unwrapping; a fully recoded render pipeline, allowing separate render passes and "render to texture"; node-based material editing and compositing; and projection painting.

Part of these developments was fostered by Google's Summer of Code program, in which the Blender Foundation has participated since 2005.

Historically, Blender has used Phabricator to manage its development but due to the announcement in 2021 that Phabricator would be discontinued, the Blender Institute began work on migrating to another software in early 2022. After extensive debate on what software it should choose it was finally decided to migrate to Gitea. The migration from Phabricator to Gitea is currently a work in progress.

Blender 2.8

Official planning for the next major revision of Blender after the 2.7 series began in the latter half of 2015, with potential targets including a more configurable UI (dubbed "Blender 101"), support for Physically based rendering (PBR) (dubbed EEVEE for "Extra Easy Virtual Environment Engine") to bring improved realtime 3D graphics to the viewport, allowing the use of C++11 and C99 in the codebase, moving to a newer version of OpenGL and dropping support for versions before 3.2, and a possible overhaul of the particle and constraint systems. Blender Internal renderer has been removed from 2.8. ''Code Quest'' was a project started in April 2018 set in Amsterdam, at the Blender Institute. The goal of the project was to get a large development team working in one place, in order to speed up the development of Blender 2.8. By June 29, 2018, the Code Quest project ended, and on July 2, the alpha version was completed. Beta testing commenced on November 29, 2018, and was anticipated to take until July 2019. Blender 2.80 was released on July 30, 2019.

Cycles X

On April 23, 2021, the Blender Foundation announced the Cycles X project, where they improved the Cycles architecture for future development. Key changes included a new kernel, removal of default tiled rendering (replaced by progressive refine), removal of branched path tracing, and the removal of OpenCL support. Volumetric rendering was also replaced with better algorithms. Cycles X had only been accessible in an experimental branch until September 21, 2021, when it was merged into the master build.

Support

Blender is extensively documented on its website. There are also a number of online communities dedicated to support, such as the Blender Stack Exchange.

Modified versions

Due to Blender's open-source nature, other programs have tried to take advantage of its success by repackaging and selling cosmetically modified versions of it. Examples include IllusionMage, 3DMofun, 3DMagix, and Fluid Designer, the latter being recognized as Blender-based.

Open projects

Since 2005, every 1–2 years the Blender Foundation has announced a new creative project to help drive innovation in Blender. In response to the success of the first open movie project, ''Elephants Dream'', in 2006, the Blender Foundation founded the Blender Institute to be in charge of additional projects, with two projects announced at first: ''Big Buck Bunny'', also known as Project Peach (a "furry and funny" short open animated film project); and ''Yo Frankie!'', or Project Apricot, an open game utilizing the Crystal Space game engine that reused some of the assets created for ''Big Buck Bunny''.

''Elephants Dream'' (Project Orange)

In September 2005, some of the most notable Blender artists and developers began working on a short film using primarily free software, in an initiative known as the Orange Movie Project hosted by the Netherlands Media Art Institute (NIMk). The codename, "Orange (fruit), Orange", about the fruit, started the trend of giving each project a different fruity name. The resulting film, ''Elephants Dream'', premiered on March 24, 2006.

''Big Buck Bunny'' (Project Peach)

On October 1, 2007, a new team started working on a second open project, "Peach", for the production of the short movie ''Big Buck Bunny''. This time, however, the creative concept was different. Instead of the deep and mystical style of ''Elephants Dream'', things are more "funny and furry" according to the official site. The movie had its premiere on April 10, 2008. This later made its way to Nintendo 3DS's Nintendo Video in May 2012.

''Yo Frankie!'' (Open ''Game'' Project: Apricot)

"Apricot" was the project name for the production of a game based on the universe and characters of the Peach movie (''Big Buck Bunny'') using free software, including the Crystal Space framework. The resulting game is titled ''Yo Frankie!''. The project started on February 1, 2008, and development was completed at the end of July. A finalized product was expected at the end of August; however, the release was delayed. The game was eventually released on December 9, 2008, under either the GNU General Public License, GNU GPL or GNU Lesser General Public License, LGPL, with all content being licensed under Creative Commons Attribution 3.0.

''Sintel'' (Project Durian)

The Blender Foundation's Project Durian (in keeping with the tradition of fruits as code names) was this time chosen to make a fantasy action epic of about twelve minutes in length, starring a Teenager, teenage girl and a young dragon as the main characters. The film premiered online on September 30, 2010. A game based on ''Sintel'' was officially announced on Blenderartists.org on May 12, 2010.

Many of the new features integrated into Blender 2.5 and beyond were a direct result of Project Durian.

''Tears of Steel'' (Project Mango)

On October 2, 2011, the fourth open movie project, codenamed "Mango", was announced by the Blender Foundation. A team of artists assembled using an open call of community participation. It is the first Blender open movie to use live action as well as CG.

Filming for Mango started on May 7, 2012, and the movie was released on September 26, 2012. As with the previous films, all footage, scenes and models were made available under a free content compliant Creative Commons license.

According to the film's press release, "The film's premise is about a group of warriors and scientists, who gather at the 'Oude Kerk (Amsterdam), Oude Kerk' in Amsterdam to stage a crucial event from the past, in a desperate attempt to rescue the world from destructive robots."

''Cosmos Laundromat: First Cycle'' (Project Gooseberry)

On January 10, 2011, Ton Roosendaal announced that the fifth open movie project would be codenamed "Gooseberry" and that its goal would be to produce a feature-length animated film. He speculated that production would begin sometime between 2012 and 2014. The film was to be written and produced by a coalition of international animation studios. The studio lineup was announced on January 28, 2014, and production began soon thereafter. As of March 2014, a moodboard had been constructed and development goals set. The initial ten minute pilot was released on YouTube on August 10, 2015. It won the SIGGRAPH 2016 Computer Animation Festival Jury's Choice award.

''Glass Half''

On November 13, 2015, ''Glass Half'' was released in HD format. This project demonstrates real-time rendering capabilities using OpenGL for 3D cartoon animation. It also marks the end of the fruit naming scheme. ''Glass Half'' was financed by the Blender Foundation with proceeds from the Blender Cloud. It is a short, roughly three-minute long comedy in a gibberish language that addresses subjectivity in art.

''Caminandes''

''Caminandes'' is a series of animated short films envisioned by Pablo Vazquez of Argentina. It centers on a llama named Koro in Patagonia and his attempts to overcome various obstacles. The series only became part of the Open Movie Project starting with the second episode.

* ''Caminandes 1: Llama Drama'' (2013)
* ''Caminandes 2: Gran Dillama'' (2013)
* ''Caminandes 3: Llamigos'' (2016)

''Agent 327: Operation Barbershop''

''Agent 327: Operation Barbershop'' is a three-minute Teaser trailer, teaser released on May 15, 2017, for a planned full-length animated feature. The three-minute teaser is uploaded to YouTube by the official Blender Studio channel. Co-directed by Colin Levy and Hjalti Hjálmarsson, it is based on the classic Dutch comic series Agent 327. This teaser film also acts as a proof-of-concept to attract funding for the full-length animated feature. ''Agent 327: Operation Barbershop'' showcases the latest technology of Cycles engine, the render engine that has been included in Blender since 2011. Assets from this teaser have been released under Creative Commons license via Blender Cloud.

''Hero''

''Hero'' is the first open movie project to demonstrate the capabilities of the ''Grease Pencil'', a 2D animation tool in Blender 2.8. It was put on YouTube on April 16, 2018. It has a roughly four-minute runtime, which includes over a minute of "behind-the-scenes" "making-of" footage. It showcases the art of Spanish animator Daniel Martínez Lara.
