Don’t worry… BabylonJS has all the toys needed… to avoid difficult programming. Often, the most difficult part… is terminology… which is needed for searches. A little greasy math in physics, but other than that, it’s all fun and there’s not much need for heavy math, ever.
Check out Necip’s “Cool Hidden Examples” thread… it’s just packed with people doing “holy crap” playgrounds… with very little code/math. Just a HUGE pile of toys. Same with the main website demos area. Yum!
One of my faves… http://www.visualiser.fr/Babylon/character/default.htm - Locate the tiny x30 button and get 30 raggies out there. Now start your favorite song on a nearby player… and then click the “F” button to the beat of the song. TOO FUN! (drool)
Also, use the arrows on the "G"ravity button, to float the pile of raggies far into the sky, then go back to G -9 to slam them into the ground. You’ll see that some of their body parts get stuck in the ground. Now try to float them with positive gravity again… FUNNY! Tap that F button to the beat of your song… then, too. Don’t forget to mousewheel in/out, sometimes, and pan-around. MINUTES of demented fun, I tell ya.
