Hi,
I would like to ask a question about ATI 9600 and 9800.
On my 9800 I can see a Texture2D calling GL_TEXTURE0 or 1 or 2 or 3... and
it works well.
On my ATI 9600 I can see a Texture2D only if I call GL_TEXTURE0...
Why?
In detail
----------
On my PowerBook G4 1GHz with an ATI Radeon 9600 (GL_MAX_TEXTURE_UNITS = 6,
64 RAM) I can see my texture I made with
glEnable(GL_TEXTURE_2D);
glEnable(GL_TEXTURE_GEN_S);
glEnable(GL_TEXTURE_GEN_T);
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
only if I call GL_TEXTURE0. In facts when I set GL_TEXTURE1, I see garbage.
On my G5 dual 2GHz with ATI Radeon 9800 (GL_MAX_TEXTURE_UNITS = 8, 256 RAM),
my same application can quite use the same texture settings with
GL_TEXTURE0, 1, 2 and 3... without any problem. And here I even use multiple
textures very well.
I don't want to believe that my ATI 9600 can run one GL_TEXTURE_2D only, and
just the number 0 only, even because GL_MAX_TEXTURE_UNITS return 6 and even
because after calling glActiveTexture(GL_TEXTURE1) the call glGetError()
returns 0.
So, where should I check for my error?
Do you think I am missing something?
Thank you for any help you could provide me.
Best Regards
