I did it like this because I wanted to create the drawing loop as efficient as possible, without switches or conditionals. That method gets executed per pixel so the less logic the better.
If someone knows a better way I'm all ears!
- bgtnhz 12y agoI fail to see the logic behind optimizing around conditionals when you are running in an interpreted language.
- mrdoob2 12y agoI instrumented the code and using conditionals resulted in 2x the generation time per loop. These loops are executed only once so the VM doesn't have a chance to optimise them.
- gavanwoolery 12y agoI've done similar in the past and can concur that it does have large performance benefits, at least in Chrome where I tested it.
- SixSigma 12y agoTesting beats imagination.
- flohofwoe 12y agoStating the obvious, but I'm pretty sure that there are no longer any purely interpreting JS engines around, it's all JIT or AOT compiled, so optimizing for a compilation scenario definitely makes sense.
