fart simpson posted:lovely lake. fart simpson posted:looks great op. how did you do the selective thickening of the voronoi lines to make the leaf veins? and the wood texture?  I don't use the 'constant' colour interpolation cos you need a bit of smoothness between levels for the bumps to show. The poo poo thing was turning the leaf outline (a cylinder going into a bunch of float-curve modifiers) into some higher resolution geometry that I could use for the voronoi bumps and general leaf shape. Is there a good way to do this? Triangulate and subdivide both gave horrific meshes with really uneven distribution of vertices, and using Boolean Mesh to cut a leaf shape out from a grid yielded one of the worst things I've ever seen, as well as taking literal seconds to calculate. In the end I did a Geometry Proximity against a Grid and it worked perfectly and took milliseconds, it just needed a bit of magic to hide the 'pixellation' on the leaf boundaries. I've made a start on Chaotic cooking. I've tried to build a Mandelbrot generator in geo nodes, Repeat zones made it easy peasy but I've got the formula wrong I guess? It's still a fractal tho so whatever  Noads:

toiletbrush posted:^^^ thats real nice, very atmospheric. ah yeah the voronoi into waves thing makes sense and the wood looks great especially for how simple it is. and the leaf outline thing... i was trying to solve the same problem and i did find a better way! you use loft curves. im building up a little asset library with different base leaf shapes defined as sets of 3 curves. (left, center, and right lines). and then i plug it into my loft curves node group and it basically takes a grid of arbitrary size and maps it onto the curves, so by cranking up or down my u and v resolutions in the loft curves group, i can get arbitrary levels of mesh detail     the loft curves group isnt that complicated. basically just takes 2+ input curves, makes them into horizontal curves running up, then maps a grid onto them.  the flip indices node i got from erindale. just some basic math two swap the directions that your indices are running

by request on the erindale discord i put the l system stuff up here if you want to download it and use it, plus i wrote up basic docs: https://deadfoxygrandpa.gumroad.com/l/qumwg also here are the blend files for my arcade and lake ones if u wanna look at them arcade: https://mega.nz/file/QNZ1WaRJ#wexPYgRK3aeGTjBjoA8TrgAbYLolA6WS86tkCzt7wm8 lake: https://mega.nz/file/JEx1ESgb#XULpiRhoO02Yen9Tde-U18-CLkp0B03ABxNjkmz3Pes fart simpson fucked around with this message at 01:52 on Nov 7, 2023 |

Thats cool! unlike this poo poo:  My Sierpinski triangle of pizza slices hasn't worked out at all, and it's the 4th or 5th thing I've tied, so I'm gonna save my energy for the next prompt. Fart that's cool, alas I deleted the blend file with the octopus cabbage

nodes are simpler today. most of my time was spent squinting at strange attractors trying to find some that looked like food or "cooking". setting them up with the new simulation zone is super easy, and then i translated and scaled them to fit the scene and applied simple materials to color them in actual attractor code aizawa attractor (the apple)   hadley attractor (the chaos donut)   genesio tesi attractor (the plate theyre sitting on)

Owns! I had some free time today so revisited my chaos pizza. Looks much better now - I wanted it to be tiled onto an icosphere but couldn't figure out the maths, but a table covered in flour will do.

toiletbrush posted:yeah that's cool, repeat zones make this sort of iterative stuff so much easier. yah with the addition of repeat zone i think you can massage geometry nodes into basically any algorithm at all. data structures and transferring data between different objects is the tricky bit but you can pull out some tricks to do basically anything
