I use geometry node and shader to create something interesting :)
Heat method to find geodesic distance???Probably, not sure if i was doing it correctly. #b3d #geodesic
Oriented bounding box PCA and O'Rourke's methods,PCA is much faster,but not that accurate. #b3d #gn
Minimum Bounding Circle Using Welzl's Randomized Incremental Algorithm,it's also pretty easy to extend to 3D,but too slow #b3d #gn #algorithms
Scribble style in GN.This idea just came into my brain. #b3d #scribble #drawing #GN
Using principal curvature to drive the direction of the lines. #sketch #b3d #GN
Using 4D simplex noise to displace a simple plane. #b3d #noise #shader
making a mistake yesterday.i shouldn't normalize the vec4 random direction. Now it is working as intended.4D Simplex Noise from scratch! #b3d #shader #noise
4D Simplex Noise and warp it using the noise derivative.Learned it from houdini cloud noise.This noise is so better than the blender noise. #noise #b3d #procudural
Compositor fx The scene only have light, no any materials.All of them are done in compositor. #b3d #compositor
