Why Iphone SDK 2.05 don't have ShadowMapping Demo


I saw ShadowMapping demo using GL_OES_depth_texture extension.

Iphone 3GS not support this extension ?


Any other shadow Algorithm to create shadow with iphone 3GS ?




At the time of this SDK release the iPhone didn’t support that extension. You can check the extensions string from GL to see what is available on the current platform.

There are various other ways of creating shadows - using the stencil buffer is one, for instance (see ShadowVolumes in the TrainingCourse folder).
