void GeomTristrips::append_unused_vertices | ( | GeomVertexArrayData * | vertices, |
int | vertex | ||
) | [protected, virtual] |
Called when a new primitive is begun (other than the first primitive), this should add some degenerate vertices between primitives, if the primitive type requires that.
The second parameter is the first vertex that begins the new primitive.

int GeomTristrips::get_num_unused_vertices_per_primitive | ( | ) | const [virtual] |
Returns the number of vertices that are added between primitives that aren't, strictly speaking, part of the primitives themselves.
This is used, for instance, to define degenerate triangles to connect otherwise disconnected triangle strips.

GeomPrimitive::PrimitiveType GeomTristrips::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.
Implements GeomPrimitive.

TypedWritable * GeomTristrips::make_from_bam | ( | const FactoryParams & | params | ) | [static, protected] |
This function is called by the BamReader's factory when a new object of type Geom is encountered in the Bam file.
It should create the Geom and extract its information from the file.
