Question

I have developed a WebGL bike configurator demo using Three.js. Given the fact that WebGL is not yet supported on iOS Safari, I have to port my app to Objective-C. Which 3D engine do you recommend?

What do you think about NinevehGL and iSGL3D framework?

EDIT: I need free/opensource frameworks

EDIT 2: I have found a great comparison of open source frameworks althought NinevehGL framework is not mentioned:

Answer 1

Given that you are comfortable with javascript I would suggest using Unity3D so you can code in UnityScript which is also ECMAScript derived.
