JAMES2503 Posted February 5, 2018 Share Posted February 5, 2018 Hi, I'm looking to procedurally grow a wire sculpture similar to the one in the photo I can do vein growth and space colonization fairly well, but I'm not sure how to create this wrapping around style Any ideas?

toadstorm Posted February 6, 2018 Share Posted February 6, 2018 This isn't a perfect solution but it might be a good starting point? I don't have 16.5 at the moment so I don't have the Edge Transport SOP; instead I'm using Find Shortest Path on the mesh to draw paths from the top of the head down into the rest of the body. From there I'm computing a "flow" vector from the generated paths that is just normalize(@P - prev_P) and then crossing that vector with the surface normal to get the spiraling curves. It's kind of like the old double-cross-product trick but with slightly more informed vectors. I'm sure a smart maths person would know how to do a better curvature analysis to get those vectors... shortest_path_curve_wrap.hip Quote Link to comment Share on other sites More sharing options...
