>>Have you tried a glHint with GL_NICEST parameter ?<<
i tried even this. glHint(GL_POINT_SMOOTH_HINT, GL_NICEST)
no way.
i am a little bit frustrated. seems i gotta billboard textured quads to go on…
thanx for the help guys
If you have the OpenGL Red Book, go and read it. It’s explained there. Btw, having GL_POINT_SMOOTH on only means that fractional components for surrounding pixels of some pixel are being calculated (in case you didn’t know)
If you dont have the book, here’s how to do it (according the book):
Enable point antialiasing (GL_POINT_SMOOTH)
Disable blending
Use alpha function that only permits fragments with alpha value greater than 0.5
thanx niftybitz but it doesn’t work.
i think some h/w renderers just don’t apply point antialiasing… maybe it works on your machine, not on mine (macG4/ATIradeon7500). it works perfectly with the same card on a PC, while it does not work with matrox G200/400/450/550 on PC’s… btw, it always works with no h/w acceleration on the configs named above
Hmm, that sucks. I have a authentic GeFORCE 256, so maybe it is hardware dependant. Strange, cuz i thought that if such a feature isn’t supported by your hw, OpenGL would surely try to emulate it in software. Well, guess you’re up to calculating the fractional values by hand
