iPhone Development

[ibly31]

Hi, I'm starting with iPhone Development. I know most of you guys are making stuff for windows, but maybe there are some Mac guys. Does anyone know a good 2D graphics library for the iPhone? I've heard of cocos2d, but I don't want some complex stuff with scenes and directors and layers, all I want is to apply surfaces like in SDL, and whatever comes last is on top. All I need is graphics because I can handle touches easily with UIKit.h. Any help?

There hasn't been an SDL port/Obj-C version for iPhone yet?

There has, but the OpenGL section of it can't be released due to NDA from Apple(blame them). It was done in the GSOC '08 I think.

Yes, it has been released, I emailed the creator, and apparently iPhone 3.0 firmware doesn't work with it... Something about OpenGL's video being different. The creator says he doesn't have the time to fix it, sadly.

Why don't you use OpenGL ES? They have sample code off of the Apple Developer site: http://developer.apple.com/iphone/libra ... /OpenGLES/

they use that for the PS3 too interestingly...

Sony's consoles don't use off the shelf OpenGL ES it's a custom version(which doesn't even use the names like glTranslate closer to sceGuTranslate(PSP func)). Now if you're talking about making stuff in linux on the PS3 it would use a more standard version of GL.

Yeah, I've tried OpenGL ES. I'd just like the process to be simpler because I have tried for hours on end just to set up a simple landscape orthagonal 2D viewport to no avail. After that, I understand how to rotate, texture, and size sprites(I call them sprites but they are really triangle strips with images on them).

Of course. It's the same with Dreamcast. the PowerVR architecture (same family of graphics chip in DC and iPhone) was designed to handle only triangle strips (extremely effing efficiently). So you render two in a 'Z' fashion. Make a function do that, it should take like 10 extra seconds.
