Method Details [hide private]

apply_scale(self, scale)

source code 
Apply scale factor on data.
Overrides: Chunk.apply_scale

set_vertices_normals(self, vertices, normals)

source code 

B{Deprecated. Use L{set_geometry} instead.} Set vertices and normals. This used to be the first function to call when setting mesh geometry data.

Returns list of chunks that have been added.

set_geometry(self, verticeslist=None, normalslist=None, triangleslist=None, matlist=None, uvslist=None, colorslist=None)

source code 

Set geometry data.
