. It can be plugged into 3DMLW Plug-in Interface and consists of a scene library and a graphics library, which provides an optimized rendering pipeline for the scene library structures. The scene library can be utilized independently for the manipulation or conversion of meshes without rendering them.

3DMLW plug-in interface

The plug-in interface mediates input events and output from host windows (e.g. web browsers) or an independent output window. It is extendible to allow integration into 3rd party software. Native support has been implemented for common web browsers.

3DMLW server toolset

The toolset provides batch conversion for several filetypes ( .obj, .3ds, .xyz, .pts) and texture atlas generation capable of processing multiple models concurrently. It can be employed server-side to provide automatic conversion of 3D models and textures.

3DMLW file format

containing instructions confined to 3DMLW language syntax: In 3DMLW 2D and 3D content are handled independently from each other, but they are free to overlap. For animating 3D scenes and handling different events a Lua scripting facility is provided. The following script snippet demonstrates colour fading: The use of 3D models in .3ds, .obj, .an8, and .blend file formats is supported, but 3DMLW Plug-in interface allows for easy extension to include other formats. 3DMLW files use .3dmlw (e.g. filename.3dmlw) as extension and can be linked together similar to
