   16 bit textures
  Hi, I'm having trouble loading my 16 bit ushort greyscale image as a texture, it seems to look all white when I draw it. From the documentation, it looks like GL_LUMINANCE would be most suitable to load a greyscale texture.Would this line of code be correct?gluBuild2DMipmaps(GL_TEXTURE_2D, 1, pImage->Width(), pImage->Length(), GL_LUMINANCE, GL_UNSIGNED_SHORT, pImage->GetPtr(0));Thanks,WF   
  Probably it is correct but try not to use old things like gluBuild2DMipmapsgluBuild2DMipmaps
