Can anyone help me understand the models that can be used in Gem?
Sure, what do you want to know?
GEM uses an opensource library called glm to load models. The models are the Wavefront .OBJ format which uses a plain ASCII text file to store the vertex, normal, and texture coordinate data. glm works well in GEM with two caveats that I know about:
- GEM doesn't allow for the separation of groups. The entire model
is loaded as one display list and uploaded to the graphics hardware.
- glm seems to have problems with parsing .obj files that have
comments between blocks of data.
Both of these are being looked into.
Are there any open source freeware programs that can work with them? Thanks,
I believe Blender will output .obj files. At some point in the near future, I hope to have GEM saving .obj files out to disk, but that won't be for some time.
