#nodevember2021 day 3-4, 4-sided

3D recursive subdivision in geometry-nodes. A popular one, but was a good exercise for me to do it purely in GN after old work in AN

Just more subdivisions. Interesting to see the approach from @FaustXins and @Bbbn192. Better randomness (and cleaner node-tree), but not sure how it would work in pure 3D subdiv.

Tentative replica of some @kilimanjaroger works. Good exercise for geometry-nodes learning.

Continuing the exercise around this series

And a third piece, though technically not pure nodes, as I pre-shattered the cylinder.

Geometry-nodes only

I wanted to try a ferrofluid-like setup for a while, and in geometry-nodes it is embarrassingly simple

#nodevember2021 day 11-20, colors in 6 combined animations

No sim, only geometry-nodes. Got the idea from a camera ad.

#nodevember #b3d #geometrynodes #loop
Each anim a different GN tree, all relatively simple.
Here the grass one. Wanted to add small leaves, but distributing points on the animated grass gives me unwanted randomness (points change) so I had to give up on it. Image
Lot of love/questions for "cloth wall" one, which is actually the simplest overall. Here the full node tree Image
Finally the "bubbly bar" (as for the bubbles one) relied mostly on points-to-volume and volume-to-mesh, affected in radius and shift by the moving ball

A collection of #geometrynodes tips and tricks (full node-tree + optional demo video)

Starting with a simple but very useful value-loop. Can tweak the RGB curve from the current linear behavior to your preferred setup.

#b3d
Can also add your tweening function in between.

Here using cx^2 + (1-c)x

(for more details about tweening see: )
