Does anyone know a vrml loader library for win32/VC++ plateform ?
Thanks a lot
Does anyone use VRML files in his 3D projects ??
I dont know about any VRML file loaders, i find them to not be the best type of model files. If you insist to use them you can make your own loader. Go to wotsit and do a search on VRML, i’m sure you’ll find some good documentation of the file.
That may not be the easiest way, but it is one way.
Good luck

Hi,
it is quite easy to write a loader for VRML-files, just take a look at the structure.
Here is an easy example
