Hi,
Is there a way how to color mesh by Ambient Occlusion in Grasshopper?
Thank you
Hi,
Is this component from any plugin ?

That’s my question. In the picture it is a dummy component. Just to show what I am looking for. I guess it will need different inputs.
Actual occlusion, or just display z-buffer occlusion like the viewports do? One involves a shader, the other lots of mesh/ray intersections.
what I understand z-buffer occlusion is a camera dependent, so when I will rotate viewport it will need to be recomputed. So actual occlusion would be way better for baking with mesh. I’m aware it will take a serious processor time.
Anyway, each of them would be helpful.

We passed 60k issues recently! Time to pull open some bubbly.

Looking forward for solution.
Hi I’m not sure why nobody mentions GH native Occlusion component…
(maybe because I don’t know what’s z-buffer occlusion?)
Caution!! very slow!!

Attempted to incorporate shadow from a light source.
Caution! really slow! Consumes 10GB memory!

Better I do this with photoshop 
.

it was just a lazy weekend’s hobby!
This might also work for very particular cases. The approach is based on Mesh | Ray intersection and I’m sure the solution can be done in a way lot cleaner manner than what I have come up with

Memory consumption was optimized. The Occlusion component has been replaced by a Python node which enabled parallel processing. Look at the self-shadowing on the bunny!
The parameters in the gh def is set to lower quality. Should run in most of the environment.
