This is awesome!

Reminds me of my own 3D engine which I discontinued because it sucked. I don't have my graphics card yet though, so I can't do anything that requires shaders.

Also,

Here are two functions that approximate sine and cosine (haven't benchmarked it yet though) : local TPI = math.pi*2 local PI = math.pi local math_abs = math.abs local math_floor = math.floor function fastSin(x) local tpi = TPI local pi = PI local t = math_abs(-2*math_floor(x/tpi+0.75) + x/pi + 0.5) ...

Limang potato!

I don't even know what I'm doing anymore.

Here's my second one: Galaxies! :D Press spacebar to change galaxies.

I think this wikipedia article would be a good read.

... I also made a small function to get the average value of numbers: function math.med( ... ) local args = { ... } local ret = 0 for i = 1, #args do ret = ret + args[i] end return ret/#args end The average is called mean (or arithmetic mean) not median. The median picks the midpoints of a (sorted)...

Konami Code still works.

Like Jeeper said, limiting frames isn't all that useful. It would be useful however, to limit frame rates if your fps goes too low (say, 6 FPS.) If that happens, you can do three things: Ignore FPS drop (this would make dt large, and thus may make your frame-by-frame calculations inaccurate.) Limit ...
