textured bitmap distortion

dantas · 2001-10-03T12:21:42

I''m using a 16x16 bitmap of a circle as a texture placed in a 2D projection over a 3D model to indicate a site of interest to the user. He can also attach a textual label to the circle. Everything works fine most of the time, except on a few locations as I move the eye position around, the circle distorts by moving the right row of pixels to the left side (always right to left, never left to right). I have GL_CLAMP for the WRAP_S/T value, so it should not be wrapping the texture. It''s only an annoyance, but it''s distracting as you move thru the model. Anyone else see this or have any ideas on what is happening? Thanks in advance.

I tried it on a few cards and drivers (what I had access to, all nVidia) and they all did the same thing. I would think that something like this would already have been found and fixed if it was a card problem. Perhaps someone on this forum from nVidia will look into it.
