Member Function Documentation

bool GeomTrifans::draw ( GraphicsStateGuardianBase gsg,
const GeomPrimitivePipelineReader reader,
bool  force 
) const [virtual]

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

Implements GeomPrimitive.

Definition at line 104 of file geomTrifans.cxx.

int GeomTrifans::get_geom_rendering ( ) const [virtual]

Returns the set of GeomRendering bits that represent the rendering properties required to properly render this primitive.

Reimplemented from GeomPrimitive.

Definition at line 89 of file geomTrifans.cxx.

References GeomPrimitive::is_indexed().

GeomPrimitive::PrimitiveType GeomTrifans::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.

Definition at line 77 of file geomTrifans.cxx.

TypedWritable * GeomTrifans::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.

Definition at line 190 of file geomTrifans.cxx.

Referenced by register_with_read_factory().

void GeomTrifans::register_with_read_factory ( ) [static]

Tells the BamReader how to create objects of type Geom.

Definition at line 177 of file geomTrifans.cxx.
