written in Houdini with vex
simple particle simulation with polar projection node written in Vex / openCL,it runs at 10fps on my MacBook. feeding multiple particles stream’s.
using this formula from wiki page: en.wikipedia.org/wiki/Stereographic_projection
(Houdini openGL rendering in 4k)
I am starting to experiment some Non Photorealistic Rendering. First I am starting off with non animation Versions.
simple point replicate rendered disc’s:
constant shader in mantra:
Working out some edge strokes and rendered with toon shader:
this time i trying to create fake occlusion with point clouds to create same NPR
I’ ve added some displacement to simulate brush strokes:
I am trying to get some pencil lines into the rendering. First tests, I am using instanced polygon lines.
I use some method like in this digraph paper to create a saintly look.
The rendering is slow and its hard to a get good reading on detailed Models. But it works much better for low poly models.
