A specialization of IffChunk for Lightwave Object files.
Definition: lwoChunk.h:29
A wrapper around an istream used for reading an IFF file.
Definition: iffInputFile.h:33
Records whether polygons are frontfacing only or backfacing also.
virtual bool read_iff(IffInputFile *in, size_t stop_at)
Reads the data of the chunk in from the given input file, if possible.
TypeHandle is the identifier used to differentiate C++ class types.
