scuy Posted September 1, 2017 Share Posted September 1, 2017 Hi, ALL I would like ask you that how i can planarize dual mesh primitive. i made attached image and hip file model. the dual mesh (attached image's random color primitives) are not planar. so i want to planarize those primitive. dose anyone know how to do it ? thank you. primitive_planar.hip Quote Link to comment Share on other sites More sharing options...
mestela Posted September 1, 2017 Share Posted September 1, 2017 That hip was empty! Anyway, a facet with 'make planar' is probably the easiest way. dual_flatten_facet.hip 2 Quote Link to comment Share on other sites More sharing options...
scuy Posted September 2, 2017 Author Share Posted September 2, 2017 Dear mestela thank you solution. i see , use "facet / make planar " it is easy way! very helpful. I want to keep each points connected .Is it possible to make planar like below link? If we accept edge and geometry shape will be changed a little bit , then we can make planar?? or there is other solution ? Quote Link to comment Share on other sites More sharing options...
mestela Posted September 4, 2017 Share Posted September 4, 2017 There's no built in relaxing things to do what that video describes, no, you'd have to build that yourself. Quote Link to comment Share on other sites More sharing options...
scuy Posted September 6, 2017 Author Share Posted September 6, 2017 Dear mestela thank you for your advice. I found one solution by blender. https://blender.stackexchange.com/questions/48/what-is-the-simplest-way-to-generate-a-dodecahedron is there anyway in houdini ? below steps are came from above reference link. ① select all the vertices in the center of each pentagon. → ② Dissolve Vertices to get rid of them → ③ Limited Dissolve（bt angle） Quote Link to comment Share on other sites More sharing options...
petz Posted September 6, 2017 Share Posted September 6, 2017 (edited) your first picture seems to show something like a saddle surface which is partly concave. i don't think that it's geometrically possible to approximate such a surface with convex hexagonal polygons which are also planar and connected. you'll always end up with concave hexagons in your case ...
