std::vector< rw::math::Vector3D< float > >	_vertices
	Vertice array.
std::vector< rw::math::Vector3D< float > >	_normals
	Normal array, there must be exactly one normal per vertex.
std::vector< rw::math::Vector2D< float > >	_texCoords
	Texture coordinate array, the texture coordinates can be mapped to either vertices or faces. The reason for this is that often vertices share two or more texcoordinates and if mapping directly to vertices then additional vertices is necessary.
bool	_mappedToFaces
	if true then the tex coodinates are mapped to faces and not vertices. if false then the texCoords are mapped to each vertice

	Transform of the object.

	Child objects.
rw::math::Vector2D< float >	_texOffset
	Offset of texture.

	Polygons ordered according to material.

Detailed Description

template<class T = uint16_t>
class rw::geometry::Object3D< T >

A concrete 3d object consisting of geometry information, material and texture.

The template parameter should be chosen based on the number of vertices in the mesh, in order to reduce memory consumption.

For a mesh that has 255 vertices or less, use Object3D<uint8_t>.

For a mesh that has 65535 vertices or less, use Object3D<uint16_t>.

For a mesh that has more than 65535 vertices, use Object3D<uint32_t>.
