I am trying to render a GL_R3_G3_B2 textures but I get only black display.
I define the texture like this:
glTexImage2D(GL_TEXTURE_2D, 0, GL_R3_G3_B2, 1024, 1024, 0, GL_RGB, GL_UNSIGNED_BYTE_3_3_2, image);
I don’t get any GL error and when I read the internal format I get GL_R3_G3_B2.
I fill the image with 0xFF (White) 0xE0 (red) etc but get only black texture.
I use the NVIDIA FX5700LE GPU.
What is wrong?
