There's a lot of stuff in ARB_fragment_program that relies on features in OpenGL 1.3 + extensions. My guess is that, since ARB_vp and ARB_fp were conceived together, the same language was just copied for both. > That said, the vertex program extensions can probably be used just fine > with OpenGL 1.2 (or perhaps older). That was my conclusion as well. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) iD8DBQFDSrUkX1gOwKyEAw8RAgz7AJ9X51eM5P+5+WZVkfGwxaQ7pYT1FACgiQG1 oxR8nzwCfwEhRsL7+6R+8VU= =aAt4 -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
