i cant fetch some adresses like: glShaderSourceARB
i did
glShaderSourceARB = (PFNGLSHADERSOURCEARBPROC)wglGetProcAddress("glShaderSourceARB"); but i have NULL

my card does not support glsl [well i have other computers but am working on old laptop ;s]

well i really don't understand code in shaders this is black magic for me :S i just want to make shadowmapping ;x

line in example

ShadowCoord= gl_TextureMatrix[7] * gl_Vertex;

gl_Position = ftransform();
gl_FrontColor = gl_Color;

this is totally wierd!

well i really don't understand code in shaders this is black magic for me :S i just want to make shadowmapping ;x

but i use intel express 945 graphic card and this i think does not support shaders and also i do not want to use them really/ i found that if i make something work in opengl for this card this will work fo ati and nvidia too with same effect

So you are trying to tell me that i should make 8 bit depth buffer? or can i make it in the other way such as?
i also have a question about
glTexImage2D( GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT24, 512, 512, 0, GL_DEPTH_COMPONENT24, GL_UNSIGNED_BYTE, 0);
i think heres the thing you mentioned? edepthcomponent 24 to unsigned byte?
