bool GeomTriangles::draw	(	GraphicsStateGuardianBase *	gsg,
		const GeomPrimitivePipelineReader *	reader,
		bool	force
	)		const `[virtual]`

Calls the appropriate method on the GSG to draw the primitive.

Implements GeomPrimitive.

int GeomTriangles::get_num_vertices_per_primitive ( ) const [virtual]

If the primitive type is a simple type in which all primitives have the same number of vertices, like triangles, returns the number of vertices per primitive.

If the primitive type is a more complex type in which different primitives might have different numbers of vertices, for instance a triangle strip, returns 0.

Reimplemented from GeomPrimitive.

GeomPrimitive::PrimitiveType GeomTriangles::get_primitive_type ( ) const [virtual]

Returns the fundamental rendering type of this primitive: whether it is points, lines, or polygons.

This is used to set up the appropriate antialiasing settings when AntialiasAttrib::M_auto is in effect; it also implies the type of primitive that will be produced when decompose() is called.
