Comparing more 3D projection methods for speed. About 100x faster on Turbowarp. 1. @TheGoodGuy2000: Very fast. To the best of my knowledge, the fastest on Scratch, but not by much. Although it uses more variables and more complex math than #3, it's about 1% faster at 5.4μs per point. (Update: a faster method has been developed. LOL) 2. @iaobardar: Quite fast, but far too much usage of trig functions, making it much slower than the other methods here. About 9μs per point. 3. @iaobardar, @ChuckSploder: Really fast, uses precalculated trig functions and optimized math for up to 55% more speed than #2. About 5.5μs per point. This was previously the fastest method (but still the simplest) for use on Scratch. Notes: I edited @iaobardar's method a tiny bit because the accuracy was off; certain variables were being changed before they could be used in the proper context. I also edited @TheGoodGuy2000's method because the X axis was inverted.
