   Problems using GL_RGB32F_ARB (texture size, interpolation)
  Hello,I am using GL_RGB32F_ARB to store real floats in my texture. The first issue I have with these float textures is, that the program crashes without telling my anything as soon as I use 2048x2048 textures (wich is the maximal texture size on my card: ATI X700). Of course such a big texture with real floats requires a lot of memory, but I was hoping that a card that supports this extension also is capabale of GL_RGB32F_ARB with a maximal texture size.  Is this a specific problem of this graphic card or do other cards have the same problem? Any experiences?Another thing is that I'd like to have an interpolation working on GL_RGB32F_ARB textures. Obviously it's not possible. Is there any suggestion to get around that?thxrapunzel
