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. | |

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

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.

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.

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.
