What do I have to learn to get done with a 3D raci

Question

I know Java pretty well. I know now most of the Basics in Objective-C. I know nothing about Photoshop. I know how to use TurboCAD 10 Professional, so I do have some experience in 3D object modelling. Although not much.

What do I have to learn step-by-step, to come to 3D game Development for iPhone? What Tools do I need? Which Books help out? How long did you learn?

Answer 1

I guess that OpenGL is worth a look.

Answer 2

Learning the basic ins-and-outs of OpenGL ES on the iPhone took me about 3 weeks. I post some of my observations on the subject here. The source code to my Molecules iPhone application, which uses OpenGL ES, is available here. Maybe you'll be able to find something useful in that example. However, there's nothing in there that deals with textures, which you'll probably need for your game. Bill Dudney has posted source code for a Wavefront OBJ modeler on the iPhone that may help in that regard. For a good text on OpenGL ES, I'd recommend "Mobile 3D Graphics: with OpenGL ES and M3G".

When it comes to Cocoa development in general, it will take you a little while to get up to speed. For me, it was about 6 months before I felt comfortable with it, although that was in the more complex Mac desktop environment. I post some resources for learning Cocoa here, although that's by no means an exhaustive list.

I agree with diciu, this is a bit much for someone just starting out on the platform. I'd find a simpler application or series of targeted applications (that you may never even release) to help you learn the core concepts before you leap into 3-D game design.

Answer 3

Your goal is very ambitious - I think it's a very hard project to tackle as the first project on the iPhone and you'd be better off starting out with a couple of simple Cocoa touch applications to get a feel for the platform.

For a simulation game I would start with experimenting with some physics engine such as bullet. Bullet is C++ and you can use it from Objective-C++.

For rendering 3D you probably want to use OpenGL ES.
