SI_MeshTextureCoords

SI_MeshTextureCoords

Specifies texture coordinates for polygon vertices.

This template allows you to define texture coordinate discontinuities at the vertex level, without the need to duplicate the vertices.

Softimage Versions

v1.3/v2.0/v3.0. Made obsolet in v3.5, this template is replaced by SI_Shape, which is nested in the SI_Mesh template.

Members

Member name	Type	Array size	Description
nTextureCoords	int		Number of texture coordinates defined.
textureCoords	array Coords2d	nTextureCoords	Texture coordinates array.
nFaceTextureCoords	int		Number of polygon vertex texture coordinate indices.
faceTextureCoords	array SI_MeshFace	nFaceTextureCoords	Polygon vertex texture coordinate indices (specifies index of texture coordinates for each vertex of each textured polygon in a mesh).

Example

Here is an example of a simple cube.

Mesh cube1 {
   8;     // 8 vertices 
   -0.500000;-0.500000;-0.500000;, // vert[0]
