Yes, I know its not the best graphic card in the world. But thats whats inside my laptop, which I love to program on.

Ok, the problem is that I cant find any way to write shaders (in Java/LWJGL) that works on this machine. In fact, I havn't even got any shader to work on my stationary computer either but at least it dont whine on "No hardware support" or something when I call glCreateShader(). If I must guess I would say thats because the graphic card only can handle OpenGL 1.4, and glCreateShader() is in the GL20-library.

But how am I supposed to use the shader funcionality in this card without glCreateShader()? Any help is welcome. This is the first time Im encountering shaders, so be nice. Smiley

Im talking about this card: http://www.intel.com/design/mobile/gma900.htm (Mobile IntelĀ® 915 Express Chipset Family)

IIRC you need GL_ARB_shader_objects and GL_ARB_shader_lang_100 support to use GLSL (which glCreateShaderObject is part of), and your card doesn't appear to be listed here so you're probably not going to be able to use GLSL at all.

However GL_ARB_fragment_program is listed, so you're not totally out of luck. I think that refers to the older asm-style interface for shaders, you might want to start looking for information on that (or use Cg, which should be able to produce code suitable).
