GraphicsComplex—Wolfram Mathematica 9 Documentation

Details and Options Details and Options

GraphicsComplex works in both 2D and 3D.
GraphicsComplex[{pt₁, pt₂, ...}, data] effectively replaces integers i that appear as coordinates in data by the corresponding .
GraphicsComplex provides a convenient way to build up meshes or simplicial complexes in which vertices of polygons are shared.
GraphicsComplex is treated like a single primitive in Graphics and Graphics3D.
In GraphicsComplex[pts, data], data can be any nested list of graphics primitives and directives.
The following options can be given:

ContentSelectable	Automatic	whether to allow contents to be selected
VertexColors	Automatic	vertex colors corresponding to each
VertexNormals	Automatic	vertex normals corresponding to each
VertexTextureCoordinates	None	vertex texture coordinates for each

GraphicsComplex[{pt₁, pt₂, ...}, data, VertexColors->{c₁, c₂, ...}] replaces Polygon[{i, j, ...}] by Polygon[{pt_i, pt_j, ...}, VertexColors->{c_i, c_j, ...}].
The VertexNormals and VertexTextureCoordinates option works the same way.
Normal[GraphicsComplex[pts, data]] substitutes coordinates to give an ordinary list of graphics primitives and directives.
