Definition at line 49 of file lwoInputFile.h.

get_filename()

Filename LwoInputFile::get_filename

(

set_lwo_version()

void LwoInputFile::set_lwo_version ( double lwo_version )

inline

Changes the version number reported for the Lightwave file.

Normally this is only called by LwoHeader as it is read.
