Clouds

Post by B.Y.O.B. » Sat Sep 29, 2018 4:24 pm

I'm currently trying to render some clouds since I stumbled upon this talk: https://youtu.be/-d8qT5-1LOI
For this I needed the remap function.
I first formed it out of nodes (the new_math_textures branch has a new "divide" texture).
But this is a) clunky to use with a lot of nodes and b) slow.

So I implemented a new "remap" texture in LuxCore. This roughly doubled my Samples/Sec.

All of this is only in the new_math_textures branch so far, I need to write the OpenCL versions before I can merge anything into the master branch.

My clouds don't look remotely like I want them, yet.
But here's a 12 minute render of the setup I have so far.
