Hello to all magicians ! So recently I've been trying to tackle a topic I never realized was going to be so painful : generate proper meshes from CAD files. The goal is to create a tool to generate clean, lowPoly meshes from CAD assets. And by CAD I mean using directly the nurbs surfaces/curves generated by the CAD software; often surfaces that are not joined really, they are just an ensemble of trimmed surfaces. If I just use a single Convert node, each surface will have its own mesh density, and what I really need is a continuous mesh allover. I've been reading quite a bit lately in ODforce forums as well as SideFX and I believe that this is still a mystery to most of us. From the information I've gathered, everything adds up to remodelling the asset using Nurbs tools... Creating profile curves, skinning, stitching, etc... but if any one has a better trick for this issue, I'm more that happy to hear ideas !! Thanks a lot
Hi, im trying to create a reptile scale tecnique, using points scattered along curves on a mesh where i'd like the scales, and i came across this amazing work by psop creating a chameleon.(https://cghow.com/making-of-jbl-chameleon/) Does anyone know how you can go from the first mesh which is the classic quad meshed character, to a remeshed version based on connecting all the scattered points on the mesh? i've tried everything i can think of... 1.triangulate2d, then restoring positions, but its not good for complex mesh shapes. 2.tetrahedralize, not so hot as cant tell it to only grab points from the surface of the mesh, it goes mad connecting innards of the mesh like a lattice. 3. i then tried "point iso cloud" which is great for laser scan reconstruction, and uses my custom scatter points to make the mesh BUT does not result in a mesh that uses my scatter points as the actual mesh points. 4. is there any mileage going down the vex route, creating a UV, then instead of searching for nearpoints in 3d space (where you could grab near points that arent actually connected on the same part of the surface of the character), and instead search distance on the UV positions of the points? 5.voronoi fracture the mesh using needed scale position points(scatter), then trying "compute dual" on the divide SOP. this feels quite close, i just need the mesh thats constructed by connecting the scatter points making lots of triangles; once ive got a mesh with the points of the connected triangles at the centre of my desired scale positions i can then compute the dual and HURRAH! ive been smashing my head against a wall for days now, id really appreciate some brain power as i think ive burnt all mine out!! cheers J Atomic14
