View Full Version : Black space between polygons



03-27-2003, 06:11 AM
To render a picture over the whole screen (for example during loading), I split my picture up into 256x256 textures, and draw the picture using several polygons. When the picture is smaller or bigger than the screen, i.e. the picture is 800x600 and the user has a screen res. of 1024x768 or 640x480, there are grey lines between the polygons. This happens on Voodoo 3 card (on Mac) and on a Matrox card. On the GeForces the problem does not happen. Do I have to disable some kind of antialiasing? Disabling GL_POLYGON_SMOOTH does not work, that's already off.

looking forward 2 ur help,

Might be texture clamping issues. Try GL_CLAMP_TO_EDGE
