It’s been awhile since I’ve written about the Sio2 game engine. For those that don’t know, Sio2 is an open source iPhone game engine that works directly with the open-source 3D modeling software Blender. It’s undergone quite a few upgrades in recent times, and has been used in the creation of many apps in the meantime.
In the most recent version all known bugs have been fixed, and there is a dramatic improvement in speed. They’ve also announced Nokia N900 support.
There’s also a new book that just began shipping that covers using Sio2 with Blender. I have to admit blender in the past has made me want to pull my own eyes out, but some people seem to love it. The book is 3D for iPhone Apps with Blender and SIO2: Your Guide to Creating 3D Games and More with Open-Source Software.
You can check out the engine at: SIO2 Interactive (to download the engine, click download, and scroll to the bottom of the page.. it’s a bit hard to find). You can also read more details about the engine, and many of it’s features not listed here, on that site.
If you’re looking for an open source iPhone 3D game engine that’s available now, and has been used in real apps, Sio2 is what’s out there, and it’s very good.
Please leave any thoughts and opinions below. Thanks.
