Detailed Description

The specialization of DXFLayer used by DXFToEggConverter.

It contains a pointer to an EggGroup and a vertex pool; these are used to build up polygons grouped by layer in the egg file as each polygon is read from the DXF file.

Member Function Documentation

void DXFToEggLayer::add_line ( const DXFToEggConverter entity)

Similar to add_polygon(), but adds a set of point lights instead.

Definition at line 82 of file dxfToEggLayer.cxx.

References add_vertex(), EggPrimitive::add_vertex(), and DXFFile::get_color().

void DXFToEggLayer::add_polygon ( const DXFToEggConverter entity)

Given that done_entity() has just been called and that the current entity represents a polygon, adds the corresponding polygon to the layer's EggGroup and vertex pool.

Definition at line 49 of file dxfToEggLayer.cxx.

References add_vertex(), EggPrimitive::add_vertex(), EggPolygon::cleanup(), and DXFFile::get_color().

EggVertex * DXFToEggLayer::add_vertex ( const DXFVertex vert)

Adds a unique vertex to the layer's vertex pool and returns it.

If the vertex was already defined previously, returns the original definition. This is designed to share the common vertices within a layer.

Definition at line 107 of file dxfToEggLayer.cxx.

References EggVertex::set_pos().

Referenced by add_line(), and add_polygon().
