Shader Experts,
I am working on a PC, Windows 2000, Radeon 9800 Pro. For my task, I've decided on programming in the OpenGL Shading Language. For an ATI card, perhaps this may not be a good idea?
I've downloaded a sample shader programs from
http://3dshaders.com/shaderSource.html (the first one, ogl2brick.zip). When I run ogl2brick.exe, I get error message "OpenGL Shading Language extensions not available"
It is produce by the following code in the program:
if ( !isExtensionSupported( "GL_ARB_shader_objects" ) ||
!isExtensionSupported( "GL_ARB_fragment_shader" ) ||
!isExtensionSupported( "GL_ARB_vertex_shader" ) ||
!isExtensionSupported( "GL_ARB_shading_language_100" ) )
{
printf("OpenGL Shading Language extensions not available\n" );
return 1;
}
I know my graphics card supports shader but the OpenGL extension names are slightly different (i.e. instead of GL_ARB_fragment_shader, I have GL_ATI_fragment_shader).
So, I removed this section of the code and rebuilt the program, but I get the following error when I try to run it:
I also get this same error when I try to run the ShaderGen program that I downloaded from
