That's just cool!
I am currently looking at "feck" and the Asteroids 3D tutorial and must say I am quite impressed!
So much impressed that I plan to create my own little LWJGL game framework based on stuff from feck and the Asteroids tutorial.
Things I realized: The Asteroids TextureLoader supports many file formats (using AWT), the feck TextureLoader only supports TGA. Why is that? To keep feck independent from AWT/Swing?
Also I tried to start the Particles test and it failed with my own particle.tga - some unexpected end of file error. Another tga worked fine. Are there different TGA formats?
Another thing: Seems the game loop in feck does not yet work like the Asteroids tutorial game loop in LWJGLWindow class with the usage of 10 ms updates and a final update for the remainder ms and a render. Do you plan to sync those?
And last question: How often do you update feck? I realized that my last downloaded version (yesterday) contains more and improved stuff than the version I downloaded months ago (out of curiosity).
And very last question: Would you consider creating a forum for feck?

Anyway, many many "thank you"s for helping LWJGL and OpenGL newbies like me with such wonderful tutorials and source codes! And the classes are well designed - it took me only a little while to get stuff working! Hats off!

Cheers,
Tommy
