TextureUpload

Last Revision:	Version 1.0, 2010-05-19 Demonstrates the fundamental techniques to obtain optimal texture upload performance.
Build Requirements:	Mac OS X v10.6 or later, Xcode 3.1 or later
Runtime Requirements:	Mac OS X v10.6 or later

This sample code demonstrates the fundamental techniques to obtain optimal texture upload performance. There are two levels of optimizations here:

- The Apple Client Storage extension allows you to eliminate a texture copy at the client.

- When working with non-power-of-two texture target (GL_TEXTURE_RECTANGLE_EXT), you may use the Rectangle Texture extension and the Apple Texture Range extension to further optimize texture upload performance.

Note, the first level of optimization applies to both GL_TEXTURE_2D and GL_TEXTURE_RECTANGLE_EXT targets; the second level of optimization applies to the GL_TEXTURE_RECTANGLE_EXT target only.

See the OpenGL Programming Guide for Mac OS X for more information, in particular, the chapter of "Best Practices for Working with Texture Data".
