Well, if you can create a velocity field that makes a hurricane like that you should be able to superimpose it into the velocity field within curly vortex. The main...

BTW, I should add, if you're looking at the curlyvortexcubemap code -- I never really got the cubemap one to work right -- always discontinuities at the face boundaries --...

I see. With a 2D solution, you may find some problems mapping onto a sphere, most typically, distortion at and near the poles. Perhaps you can live with the distortion,...

Well, the band speed is along the lines of cos(NumBands * Latitude) at the moment. If I can think of some clever formula, maybe, but nothing's immediately springing to mind.

Good idea!

Hmm, so the velocity field is actually a 3D field of vectors that are constrained to be tangent to the surface of a sphere. I suppose I could transform to...

Thanks for the example image, had done some google image searches for flow maps, but wasn't sure what I was looking at. Now just have to remember/relearn about tangent space,...

Looky what I made:  I can't believe that worked the first time. Zero debugging. Which probably means that it didn't actually work and there's something wrong with it, but...

Committed as: * f5c1299fd2e29524947c28a07c9fc9c99c1dba7d Allow exporting velocity field as flow-field png files To use it, just add command line flag "--dump-flow-field filename-prefix" It will dump out six png files named...
