The loader that gets used is automatically determined from the file
extension. Thus there is no need to specify it explictly. Try:
pfNode *model1 = pfdLoadFile("robot.flt");
pfdLoadFile builds in-memory data structures from an external database
file. The filename's extension is used to determine the file format.
If
no path to the file is given, the directories in the active Performer
file search path (see pfFilePath) are scanned for the given filename.
pfdLoadFile may only be called after pfConfig.
