Subdivision surfaces are supported by mental ray when the library
libmisubdiv.so is linked in. This library implements the
Loop subdivision scheme for triangle meshes, and the Catmull-Clark
subdivision scheme for quadrilateral meshes. The following features
are available with this library:
- C/C++ API for subdivision surface construction and manipulation.
This API can be used by geometry shaders to create renderable
subdivision surface objects.
- Smooth, dart, conic, cusp and corner vertex features.
- Crease edges with fractional sharpness.
- Adaptive local refinement and tessellation, visibility culling.
- Texturing with unlimited number of texture spaces, motion blur.
- Trim regions by trim edge specification.
- Multiresolution editing with wavelet decomposition and variable
data-dependent smoothing.
- Export of subdivision surfaces to NURBS.
