[gl4java-usergroup] Re : The new project...

I disagree.  I don't want to have to use your (or any specific) engine just
to get some useful utility functions for file loading.  Parsing a 3D Studio
file is difficult on your own, and if someone could write a method to parse
it and stick it in a wrapper class (like 3DStudioFileWrapper) with get()
methods for all the important data, that would be a HUGE help.  That doesn't
have anything to do with storing polygons, etc.  It just exposes the file's
important information for reading in a much more object-oriented fashion.
This of course could be done with many major file formats.

Thoughts?

My opinion is that it is not the role of an OpenGL Binding to handle
file loading, because it requires to set up specific data structures to
handle the storage of polygons, to manage matrix transformations of
objects, textures and cameras (I assume if you want to load an object,
you also want to rotate around and examinate it) : this the purpose of a
3D engine and it goes beyond the scope of gl4java.

This is why I have started the OpenMind project : it is a 3D engine on
top of gl4java. It actually features most of the functionalities you are
looking for and the code is also open source. It currently loads 3dsMAX
ASE files, and soon parsers will be developed to handle .md3, .3ds and
.obj files. We always need open source developers I want to code a
parser :)

So if you want to give it a look : http://www.mind2machine.com
