Hi. I'm developing a game engine to be used both in Desktops and PDAs... I recently converted the projects vector math and opengles calls to fixed point and I'm experiencing some problems ever since.
If I use floating point, the scene shows up fine in the PDA. If I use fixed point, however, the geometry loads ok, but everything is black (everything but the background, which has the right color). I tried making texture loading fail, and deleted the texture files from the project. That causes everything to be white in floating point, but it's still black with fixed point (made no difference if the texture files were there).
I'm kinda new to opengl, so I was wondering if you could help me figuring this out. Any ideas on what could the problem be (or a procedure to debug this! I have no clue how to do it)?
