Member Function Documentation

bool GeomLines::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 116 of file geomLines.cxx.

int GeomLines::get_min_num_vertices_per_primitive ( ) const [virtual]

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

Reimplemented from GeomPrimitive.

Definition at line 105 of file geomLines.cxx.

int GeomLines::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 lines, 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 line strip, returns 0.

Reimplemented from GeomPrimitive.

Definition at line 94 of file geomLines.cxx.

GeomPrimitive::PrimitiveType GeomLines::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 78 of file geomLines.cxx.

TypedWritable * GeomLines::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 184 of file geomLines.cxx.

Referenced by register_with_read_factory().

void GeomLines::register_with_read_factory ( ) [static]

Tells the BamReader how to create objects of type Geom.

Definition at line 171 of file geomLines.cxx.
