Since I’m not familiar with iPhone development I’d like to know whether it is possible to use OpenGL ES1.0 on the iPhone 3gs rather than 2.0.
I’d like to share a code base across different mobile platforms and not having to deal with the programmable pipeline from OGLES 2.0 could speed up an initial build.
Update — I’m not used to working with OpenGL Es, but is there a always complete backward compatibility or do phones sometimes only support the latest version, eg 2.0
Thanks
Yes, you can. Simply call the OpenGL ES 1.0 APIs. The hardware is a full 2.0 device, but the software/driver can implement an OpenGL 1.x pipeline for you.
