Member Function Documentation

bool GeomPoints::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 133 of file geomPoints.cxx.

int GeomPoints::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 88 of file geomPoints.cxx.

References GeomPrimitive::is_indexed().

Returns the minimum number of vertices that must be added before close_primitive() may legally be called.

Reimplemented from GeomPrimitive.

Definition at line 122 of file geomPoints.cxx.

If the primitive type is a simple type in which all primitives have the same number of vertices, like points, 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 point strip, returns 0.

Reimplemented from GeomPrimitive.

Definition at line 111 of file geomPoints.cxx.

GeomPrimitive::PrimitiveType GeomPoints::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 76 of file geomPoints.cxx.

TypedWritable * GeomPoints::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 158 of file geomPoints.cxx.

Referenced by register_with_read_factory().

Tells the BamReader how to create objects of type Geom.

Definition at line 145 of file geomPoints.cxx.
