------- Additional Comments From willie@froq.net 2005-06-11 18:53 ------- The ATI_texture_float extension is not available on Nvidia cards/ with Nvidia drivers, and it's not approved by the OpenGL ARB. There's ARB_texture_float (based on ATI_texture_float, just slightly different), but I don't know about driver/ hardware support (my Nvidia Quadro FX3000 with 1.0.8xxx beta drivers doesn't support ARB_texture_float).
