This is all very exciting. Years ago (for the Bangle 1) I wrote an STL viewer that does some of the heavy lifting in C (viewstl in the app store). Back then I did all the math library function (mostly trig functions) in JS and passed the results into C (simple arithmetic fp ops worked fine, albeit not using the fpu).
I have a half-finished Space Shuttle lander game that uses 3d graphics. My approach was to fill arrays with polygon screen coordinates in C and then call graphics routines in JS, but your approach of accessing the screen buffer directly from native code seems better performance wise, Felipe. I might adopt that approach, thanks for figuring all this out, very impressive!
