I am starting out with OpenGL ES. The example code that I am reading has a lot of functions whose names end in OES. What does the OES suffix mean? The non-OES counterparts have man pages but I cannot find any documentation on the *OES functions. Would it be okay to use the non-OES man pages as a reference?
The
OES-suffixed functions exist because framebuffer objects are supported via theOES_framebuffer_objectextension on OpenGL ES 1.1, but are part of the core specification in OpenGL ES 2.0 (and therefore don’t need an extension suffix).The man pages for the non-suffixed OpenGL ES 2.0 functions should map pretty closely to the
OES-suffixed versions, as the rules forOES_framebuffer_objectalso apply to framebuffer objects in OpenGL ES 2.0.
