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.

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 co开发者_运维技巧de 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.
