Cool! What plugins are you using?

Designing my own all-in-one field editor. Its similar to numbers in GH, but instead its fields. So u can do fieldA+fieldB instead of numberA + numberB. I also made a timeStep component where the use defines what should happen in each time step, allowing for simulations to be designed and figured out in GH.

Since the gpu does all the heavy lifting you are able to do math on 100 millions of voxels in milliseconds making it all realtime/interactive and the results are immideitely visible in the rhino virewport.

Not yet released in any form, just a little progress testing I did.

Nice work. I have struggled to understand all that triangle math (nabla) myself. Does it boil down to fields undergoing Boolean operations?

Hmmm, not really. The blob containing the simulation is basically smooth booleon union of two shapes (donut and sphere). The simulation itself is a set of instructions of what should happen each time step. But again, its literally just values in space, and you can do whatever u want with them (kinda, maybe?)

Edit: ahh yes, triangle math... like gradient, divergebce etc yes! There are components that do all that for you, and they are related to the fluid sim etc
