For years I have been wanting to implement a version of my 3D noise function that produces the same result on the CPU and GPU. But I also wanted it to do other things as well:<\/p>\n
(1) It needs to use only standard WebGL and Javascript
\n(2) It can’t require loading any data tables
\n(3) It must run insanely fast — even on my phone<\/p>\n
Well, I finally got around to it. I’ve posted a little side by side test of the GPU and CPU implementations, together with the source code for each.<\/p>\n
The test shows an X,Y slice of 3D noise traveling in Z over time.
