Creating models for a game

[spikeyfish2]

Well, I was thinking about how I would go about making objects for an iPhone Game. When I think of a simple 3d modeler, I think of Google's Sketchup. It's really easy to use, and surprisingly good quality (when used properly). Would it be possible to use that to make models for an iphone game. Also, how would I export the model for use in an iPhone game?

If you look thru my posts you can find some sample code on loading OBJ format 3D models into your iPhone application. You basically parse in all the vertices and properties into proper structure arrays then use openGL to render these arrays.

Hi guys my first post! I just wanted to mention the md2 format for iPhone. There is a rather good example here. One issue I'm dealing with at the moment is the key frame animation. This format stores all the vertices for each frame and then interpolates them every frame. This is currently causing the greatest bottleneck in my game.

I'm just curious is the obj format better suited to the iPhone? Does it support animation?

Well the pro to the OBJ format is that its very portable. If you're doing animation its probably the wrong choice though.

I just found this thread which has an interesting post about the POD format.

I just wanted to mention that removing the interoplation for the md2 animation reduced the 20% bottleneck seen in Shark to 0%. So if you use md2 for animation I suggest you remove it.

Thanks for the link! it looks like one can learn a lot from that example project.
