Porting OpenGL project from Visual Studio to Xcode

Question

I'm in the process of converting/migrating a Visual Studio OpenGL project to an Xcode (iPhone) OpenGL project.

Do you have any experience or suggestions?

Answer 1

You need to understand the limitations of OpenGL ES 1.1 and the performance of the hw in the iPhone, ie one can't use glBegin/glEnd so all vertex data has to be passed as arrays and GLU things are missing. See here for some performance stats.

If your OpenGL code is fairly straight forward Apple supplies a good template to get going with it. I have created a screencast where I demo a AC3D lib, 15s in I start with a clean Xcode OpenGL ES project.
