int LwoPolygons::get_num_polygons (   )  const

Returns the number of polygons of this group. Definition at line 39 of file lwoPolygons.cxx. References _polygons, nassertr, and NULL.

LwoPolygons::Polygon * LwoPolygons::get_polygon (  int  n  )  const

Returns the nth polygon of this group. Definition at line 52 of file lwoPolygons.cxx. References _polygon_type, DCAST, IffInputFile::get_be_uint16(), IffInputFile::get_bytes_read(), IffInputFile::get_id(), LwoInputFile::get_lwo_version(), IffInputFile::is_eof(), PF_numverts_mask, and PT.

virtual TypeHandle LwoPolygons::get_type (  void   )  const [inline, virtual]

Reimplemented from LwoChunk. Definition at line 82 of file lwoPolygons.h. References _type_handle, LwoChunk::init_type(), and register_type().

void LwoPolygons::init_type (  void   )  [inline, static]

Reimplemented from LwoChunk. Definition at line 89 of file lwoPolygons.h. References _type_handle.

IffChunk * IffChunk::make_new_chunk (  IffInputFile *  in, IffId  id )  [virtual, inherited]

Allocates and returns a new chunk of the appropriate type based on the given ID, according to the context given by this chunk itself. Reimplemented in LwoClip, LwoSurface, LwoSurfaceBlock, LwoSurfaceBlockHeader, and LwoSurfaceBlockTMap. Definition at line 66 of file iffChunk.cxx.

bool LwoPolygons::read_iff (  IffInputFile *  in, size_t  stop_at )  [virtual]

Reads the data of the chunk in from the given input file, if possible. The ID and length of the chunk have already been read. stop_at is the byte position of the file to stop at (based on the current position at in->get_bytes_read()). Returns true on success, false otherwise. Implements IffChunk. Definition at line 76 of file lwoPolygons.cxx. References LwoInputFile::get_vx().
