I finally got around to checking these out and its really promising! I’ve always wanted to do volume sampling in Blender.
- I can color my mesh the correct color when going from volume to mesh
- I can now do particle surfing!
First. Look at it! I have a colored mesh from a volume using the volumetric data!
Particle Surfing
I loaded in an ocean temperature vectorfield dataset I created. Then using simulation nodes, spawned particles in and sampled the vectorfield and added that to their velocity. It’s so cool!
And since its geometry nodes there’s like endless ways to visualize the data.
I can color them based on acceleration
Based on vertical velocity
Scale them by age
A lot more stuff I don’t want to spam.
One bug I’ve noticed so far.
If you are using a VDB sequence the sampling doesn’t work for some use cases. For volume to mesh it works. But I decided to just spawn points in the volume and sample. the sampling fails when the frame changes. You have to connect the input → output then reconnect your nodetree again and then it samples again correctly.
Otherwise, I’m super excited!
