I’m looking for a way to model “naturalistic” rocks that transition into cut stone. Somewhat like this photo here:
I tried a number of different strategies for the rough rock, based on these resources:
Using Simplex Noise: https://discourse.mcneel.com/t/stone-wall/82036
Using Image Sampling: https://www.grasshopper3d.com/forum/topics/how-to-make-stone-surface-into-grasshoper
Using a Cellular approach: https://www.grasshopper3d.com/forum/topics/rocks
I think out of those the simplex noise is closest to what I’m after. I want it to hint at looking realistic, but can add textures later in VRay or Photoshop. For the blocks themselves I have tried both using a grid with an attractor point and using panels from lunchbox.
In short, I am trying to figure out a smart way to parametrically and seamlessly transition from a noisy object to smooth blocks.
I want to be able to:
A) Make the transition from rough rock to multiple blocks, as if the blocks were being carved out of the stone
B) I want to be able to control the number of blocks and scale
C) I want to be able to control the transition point from rough to smooth and adjust the “tween” to make it a wider or more abrupt area of transition.
If anyone has any suggestions it would be super helpful- even things like plugins or links to forum posts that may be relevant. Thank you.
