[PyOpenGL-Users] Textures on Bad Hardware

[Ian M. <geo...@gm...>]

Hi,

So, my laptop has got a decent graphics card, processor, RAM, etc.  Using
it, I developed several programs using textures, shaders, etc.

My brother, with a netbook, wants to run some of these programs.  The
computer, which is available <a href="

an Intel integrated graphics chipset.

I understood that such graphics cards have poor support for GLSL, but upon
running the (shader-less) code on his Intel hardware, all of my texturing
code failed (on the glTexImage2D(...) call, with invalid operation), whereas
it works perfectly on my computer, and on several others, Mac, PC, and
Linux, and NVidia and ATI.

The code is written in Python, and for my test program, I wasn't doing
anything fancy, just setting up a standard OpenGL 2D texture.  Through games
that work on his computer, I'm pretty sure that (DirectX?) texturing works
(Motocross Madness) and that OpenGL texturing works (Tux Racer).

I'm setting up the texture with standard OpenGL routines (and after I've set
up a context, etc.).  The glTexImage2D() calls give invalid operations no
matter what.  I'm passing them string buffers with GL_UNSIGNED_BYTE:
pygame.image.tostring(data,"RGB",True)

So . . . I don't think it's any particular setup; all the texturing code is
failing.  Do PyOpenGL textures work on Intel cards?  Or is this something I
don't know about?  Or what?
