The ATi Linux driver
Sunday, November 24, 2002 | Permalink
ATi has taken a large step forward in terms of Linux support in my eyes with the new drivers from a few days ago. I had severe trouble with the previous Linux driver and never got it to work, with this driver however I got it up and running quite soon with little trouble. I'm posting this news from within Mandrake Linux 9.0 now and have runned a variety of 3d applications and have had success in every case. Heh, btw, Tux Racer rox.
In terms of extension support this driver seams to support pretty much everything that the Windows driver does. The complete list of the glGetString(GL_EXTENSIONS) return is:
GL_ARB_multitexture
GL_EXT_texture_env_add
GL_EXT_compiled_vertex_array
GL_S3_s3tc
GL_ARB_depth_texture
GL_ARB_fragment_program

GL_ARB_shadow_ambient
GL_ARB_texture_border_clamp
GL_ARB_texture_compression
GL_ARB_texture_cube_map
GL_ARB_texture_env_add

GL_SGIS_multitexture
GL_SUN_multi_draw_arrays
I suppose there's some kind of counterpart to the wglGetExtensionString() call in Linux for GLX specific stuff, but I'm still a newbie in this, but expect some Linux demos in the future. I'm not sure how much effort I'll need to put into convincing my framework to run in Linux, but it won't be a quicky.

who are the common OpenGL extensions for these NV extensions?
int fattributes[] = {
WGL_DRAW_TO_PBUFFER_ARB, GL_TRUE,
WGL_SUPPORT_OPENGL_ARB, GL_TRUE,
WGL_PIXEL_TYPE_ARB,
WGL_TYPE_RGBA_ARB,
WGL_FLOAT_COMPONENTS_NV, GL_TRUE,
WGL_BIND_TO_TEXTURE_RECTANGLE_FLOAT_RGBA_NV, GL_TRUE,
WGL_RED_BITS_ARB, 32,
WGL_GREEN_BITS_ARB, 32,
WGL_BLUE_BITS_ARB, 32,
WGL_ALPHA_BITS_ARB, 32,
0};
wglChoosePixelFormatARB(hdc, &fattributes[0], NULL, 1, &format, &nformats);
...
and
int battributes[] = {
WGL_PBUFFER_LARGEST_ARB, GL_TRUE,
WGL_TEXTURE_TARGET_ARB,
WGL_TEXTURE_RECTANGLE_NV,
WGL_TEXTURE_FORMAT_ARB,
WGL_TEXTURE_FLOAT_RGBA_NV,
0};
m_hPBuffer = wglCreatePbufferARB(hdc, format, m_iWidth, m_iHeight, &battributes[0]);
...
I need port this NV source code to compatible OpenGL and use this with my ATI 9800.
thanks.
