Blending on none geforce cards ?

[jonas]

Hi

I have made a little prog that has a water texture which I have made transparent using GLBLEND. On my geforce it works like a charm but in school the water texture isnt transparent. I dont know what gfx card they have in school but I guess it doenst have a 3d accelarator.

Has anyone else encounterd the same problem ? any solutions ?

As blending works fine in openGL software mode I think there is a miserable GL-driver/GL-card in your school, e.g. ATI. They support only some openGL features (those to get Quake running). The others are badly or not implemented.

okey. Thank you.

Kilam, you should have said Ati Rage Pro. The newer card Rage 128, Rage 128 pro, MAXX and the Radeon have all the blending mode.

Cards with a Riva128 chip (like a Viper330) don't blend correct too.
try this:




glBlendFunc(GL_ONE, GL_ONE);


this sometimes works better for these cards. It's not the best blend mode, I know ... but hey, what ya gonna do about it? http://www.opengl.org/discussion_boards/ubb/wink.gif
