Tess3D

Detailed Description

group a3d_tess3d

Tessellation for solids and surfaces.

Entity type is kA3DTypeTess3D.

An A3DTess3D is a tessellation dedicated to solids and surfaces. This structure is a derivation of A3DTessBase and can be obtained by using the A3DTessBaseGet function on any A3DRiRepresentationItem. This structure may contain collections of points that define mesh vertices, normals (per vertex, per entity), and UV coordinates if textures are stored.
