Methods
shapes
()Iterate through the items in this primitive. Attributes
normal
Read-only numpy.array of size Nx3 where N is the number of normal values in the primitive’s normal source array. normal_index
Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. texcoord_indexset
Read-only tuple of texture coordinate index arrays. texcoordset
Read-only tuple of texture coordinate arrays. vertex
Read-only numpy.array of size Nx3 where N is the number of vertex points in the primitive’s vertex source array. vertex_index
Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. -
shapes
()¶ Iterate through the items in this primitive. The shape returned depends on the primitive type. Examples: Triangle, Polygon.
-
vertex
¶ Read-only numpy.array of size Nx3 where N is the number of vertex points in the primitive’s vertex source array. The values will be transformed according to the bound transformation matrix.
-
normal
¶ Read-only numpy.array of size Nx3 where N is the number of normal values in the primitive’s normal source array. The values will be transformed according to the bound transformation matrix.
-
texcoordset
¶ Read-only tuple of texture coordinate arrays. Each value is a numpy.array of size Nx2 where N is the number of texture coordinates in the primitive’s source array. The values will be transformed according to the bound transformation matrix.
-
vertex_index
¶ Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. To get the actual vertex points, one can use this array to select into the vertex array, e.g.
vertex[vertex_index]
. The values will be transformed according to the bound transformation matrix.
-
normal_index
¶ Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. To get the actual normal values, one can use this array to select into the normals array, e.g.
normal[normal_index]
. The values will be transformed according to the bound transformation matrix.
-
texcoord_indexset
¶ Read-only tuple of texture coordinate index arrays. Each value is a numpy.array of size Nx2 where N is the number of vertices in the primitive. To get the actual texture coordinates, one can use the array to select into the texcoordset array, e.g.
texcoordset[0][texcoord_indexset[0]]
would select the first set of texture coordinates. The values will be transformed according to the bound transformation matrix.
