well obviously, there’s no scientific grapher directly in Particular.
I think a point-cloud approach might work in some cases, where you loop a random value or a try values value from a grid, untill your expression is true.
That way 1 particle per frame would be created on a location corresponding to your borg cube formula.
This would be an absolute monster to render/calculate, because the expression could theoretically have to try millions of values before stumbling on one that’s ok, and that will just result in one particle.
Perhaps there’s some mathematica wolfram research genius that knows how to export a point-cloud as a parseable-text-file or just a CSV. (I’ve never worked with that program)
If so, you could paste the contents of that csv in a text-layer and read the values from that…
An expression for doing that shouldn’t be too hard to code.
