Hey guys!
I'm very very new to OpenGL. Sorry if my mistake seems trivial to you. I assure you I tried everything I could think of first.
I'm trying to load this 3ds model in an Android application:

I parsed the 3ds file correctly and drawn them all but it seems that some of the vertexes/faces are missing. Here's how it looks rendered (and rotated a bit). I'm aware that I have no lightning /normals/shading for it but before I get there, shouldn't all the peaces still be drawn correctly?

Any idea why this is happening? (it seems to happen for any other model I load - big chunks are missing).
