Reimplemented from DisplayObject.

◆ TessVertices()

Vertex * TessVertices ( )

inline

Gets the object's tesselated vertices.

Returns: Pointer the the object's tesselated vertices

◆ VaListSetVertices()

virtual void VaListSetVertices	(	unsigned int	nPoints,
		va_list	args
	)

virtual

Sets the vertex data for this object You should call UpdateBoundingVolume after changing an object's extents.

Parameters

nPoints	The number of vertices in the object
args	va_list in the form r,g,b,a,x,y,z for each vertex
