Open source alternatives

Hello everyone,

I have recently been looking around for development software to throw together some games and/or AI research projects. Torque and Unity do look interesting but I was also wondering about open source alternatives.

Now I am quite familiar with Qt4 and like it quite a bit but I if I decide that my project is good enough I may want to sell it and under the GPL I would not be able to do so. Because of this LGPL would be preferable but I am still interested in GPL products as well as research projects would most likely not turn in to marketable products.

With that out of the way I wanted to know if anyone had any experience with the following packages or can suggest any other ones that they have found helpful when developing on OS X or PPC based Linux.

Orge - http://www.ogre3d.org/
ClanLib - http://www.clanlib.org/
Open Dynamics Engine - http://ode.org/
Bullet - http://www.continuousphysics.com/Bullet/

Thanks for the help in advance,
Sam

Hay thanks PowerMacX. I had completely forgot about that package. Before I started in Comp Sci I had downloaded the screensaver version of this.

You may want to check out Irrlicht also.

I have used Ogre and only have good things to say about it. The initial setting up an app (without using their tutorial class) can be tricky, but all the rest is a rather small learning curve. I recommend at least trying it out. Plus it has lots of advanced features that you can use without having to know how they work.

Hay BronxBomber92,

I have never heard of Irrlicht before but it looks quite promising. What is your experience with it? How about as opposed to other open source packages like Ogre?


Hi Nick,

Good to hear as I have looked over Ogre (even got it to compile on my machine) but just have not had the chance to play around with it. What other tools do you use with it for development (if any) and do you have any other tips or resources that might be of interest?


Thanks to both of you,
Sam

Pretty much anything you want. Ogre reads in a proprietary 3D model file format, but luckily there are exporters and converters for nearly any program or file format. As for images, again, you can use just about anything. If you don't have money to spend, I'd suggest the Gimp. Otherwise Photoshop is still the king (but will cost you).

I prefer Irrlicht. You can't really Irrlicht and Ogre. Irrlicht is a game engine, while Ogre is rendering engine. So it depends what exactly your looking for. I was never able to setup Ogre on a Mac, so I can't comment on it too much. Irrlicht's community is very helpful, there tutorials are great, and the support for different file formats is great! http://irrlicht.sourceforge.net/features.html

Ogre is better graphicaly, but I think you'll find Irrlicht more suited for you. But that is just my (bias Wink) opinion. As I said, I've never been able to use Ogre.

Well that is good to know so thanks again. How about 2D open source engines? I would prefer C++ (or rather non-scripting based) engines. Any suggestions?
