Displaying 3D objects

[MrTAToad]

At the moment, I'm having problems rendering 3D objects properly (it was converted to ddd from a 3DS file).  It displays the sides, but not the top or bottom, and thus is not a totally solid object.

It also seems to be a problem with manually created shapes too :

I think the CreateSphere code is ... not the best.
Try different num_wrap and num_stacks values.
Try the ones I use in my "lights" sample.

It turns out that the background image (which does have an alpha) was being used on the 3D object, and thus a quarter of the shape was missing.

I had thought that by default each object would have no texture, but apparently it uses the last texture used

So, problem solved.
