collada.primitive.BoundPrimitive

class collada.primitive.BoundPrimitive

Bases: object

A collada.primitive.Primitive bound to a transform matrix and material mapping.

__init__()

Initialize self. See help(type(self)) for accurate signature.

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.
