Public Attributes
std::string	_name
	name/id of object
int	_parentObj
	index of parent object
bool	_hasTexture
	true if any of the materials used has texture
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
rw::math::Transform3D< float >	_transform
	Transform of the object.
std::vector< Object3DGeneric::Ptr >	_kids
	Child objects.
rw::math::Vector2D< float >	_texOffset
	Offset of texture.
rw::math::Vector2D< float >	_texRepeat
	Repeat texture.
std::vector< MaterialMapData >	_materialMap
	maps material into a range of triangles.
std::vector< MaterialPolys::Ptr >	_matPolys
	Polygons ordered according to material.

Detailed Description

An abstract 3d object consisting of geometry information, material and texture.

To reduce memory, the geometry is implemented slightly differently for different mesh sizes. One of the concrete Object3D implementations should be used in practice.
