A digestible introduction to the wave equation with working code
- raverbashing 13y agoVery interesting And a good example of why the 'exact' solution is often not used, because it's so slow
- jheriko 13y agoits not an exact solution, and actually the implementation is just very poor. highly optimised versions of this have been around for 20 years or more running with /software/ rendering. you can boil the whole thing down to a convolution matrix type trick which a modern gpu will eat for breakfast. i should find some time and do one of these... the quality of 'impressive webgl tech demo' seems to be about 15 years out of date in general...
- CamperBob2 13y agoIt's a pedagogical exercise, not a cycle-counting contest. GPU acceleration amounts to premature optimization when your goal is learning the basic math.
