Old Reference
The link to Apple's OpenGL shader builder was to a document on Apple's dev site last edited in 2004 which did not reflect the current version of the OpenGL Shader Builder. I updated the link to a more recent user guide (mid 2008) which more accurately reflects the usage of the program as it is included in XCode 3. If I find a more recent version of the user guide I will again change the link. 128.119.40.196 (talk) 14:42, 12 November 2009 (UTC)
