I've just designed my own 3D engine, with rotation around each axis,zoom, etc.
I'm now gonna start working on turning it into a tutorial so that everyone gets to understand the way these cubes work. It is really impossible to get it just by looking at the flas so I dug out the formulas on the Web and worked it out n my own. Anyway, I'll explain everything in the tutorial.
Thanks, KStor - I'm looking forward to it. If you need any help, contact me privately. My background is mathematics and aerospace engineering with specialization in computational geometry and flight dynamics. I wrote 3D modeling and animation software from scratch 20 years ago (yes, I'm an old dude).
Your willingness to work this information into a tutorial is greatly appreciated. I hope it brings you great FlashKit fame
