, non-uniform rational mesh smooth (NURMS) or subdivision surface technique is typically applied to a low-
polygon
In geometry, a polygon () is a plane figure made up of line segments connected to form a closed polygonal chain.
The segments of a closed polygonal chain are called its '' edges'' or ''sides''. The points where two edges meet are the polygon ...

Autodesk 3ds Max, formerly 3D Studio and 3D Studio Max, is a professional 3D computer graphics program for making 3D animations, models, games and images. It is developed and produced by Autodesk Media and Entertainment. It has modeling capa ...
to perform mesh smoothing operations. The mesh smooth modifier in 3ds Max operates by applying this algorithm to a low-polygon mesh and creates a high-polygon smoothed mesh. The new mesh can be dynamically manipulated by the low-polygon mesh to achieve the desired results.
There is also an Adobe Illustrator filter that uses the same algorithm of smoothing for 2d curves.
