How can I find out how much space is occupied by a texture (in bytes)? How well does glTexSubImage2D work? I mean... can I load eight textures every frame? ...
It sounds like a good idea to have some configurable alpha noise automagically blended over the image by the mag filter :) It's a pity that it's not...
I'm becoming interested in developing some (non-game) OpenGL-based force-feedback applications, possibly using some of the game joysticks such as the Saitek...
Hi, I'm just looking at the SGIS_generate_mipmap specs, and it defines a lot of interesting filter modes, but they seem to be not documented at all (or is it...
Hi. I'm new to OpenGL and I'm trying to implement 360' fisheye view. I already examined papers and sample code on this subject, but some practical details are...

Dear All, Since this is my first posting, I would just like to say that this mailing list has been a joy for me to read for the last year. I have a question...
Two questions about projective texture mapping(PTM). Firstly, is it allowed to use glTexImage2D to set texture instead of gluBuild2Dmipmaps in PTM? As long as...
Hi. I have a problem projecting multiple textures on polygons by using projective texture mapping. So far, I tried to modified the "projtex.c" at the ...
Hi, just three short questions. 1. I was just told at the cgShaders forum that the z-value of a homogenous points ranges from -1.0 to 1.0. I thought it would...
I would like to make an easy, simple font for 2d rendering. A bitmap font seems logical. I want to create the font on my own though, and use display lists and...
Hello all, I did a program that used multi-texture and automatic texture coordinate generation to make a haze effect. The haze texture is applied to the object...
Hi all, I have a program which positions a series of glutBitmapStrings on the screen relative to the x,y screen coordinate of the mouse. This works fine, ...
Dear all, I'm trying to model lightning using opengl, and I need a lightning texture to test it out. Does anyone have a texture I could use, or know where I...
