mapping from one mesh to another
7 Replies

Hi all,I've been trying to map one mesh to another using the MeshCP and MEval components, hoping to use for mapping one "pattern," or "gradient" from one to another, and from 2d to 3d and vice…Continue

MeshEval Issue

Hi all,I am experiencing some issues with the MeshEval component.Firstly, when the corresponding mesh and parameters are plugged in, the points returned are not the same as the points input.Secondly,…Continue

Hi all,I've been wandering around the discussion forum and some other places but can't seem to find a good place to start regarding the problem of remeshing a triangular mesh to a quadrilateral one.…Continue

pairs of closest points

Hi all,I am wondering if anyone has any advice on the problem of finding pairs of closest points in a collection of points.By this I mean, different from what Proximity2D does, for example, if there…Continue

"another approach/question would be, is there a way to split the periodic mesh along a seam? so that the start and end edges coincide but are not the same. Thanks again!"

mapping from one mesh to another

Hi all,I've been trying to map one mesh to another using the MeshCP and MEval components, hoping to use for mapping one "pattern," or "gradient" from one to another, and from 2d to 3d and vice versa.I noticed that while the process works for 2d to 3d, it somehow doesn't work for 3d to 2d as in the attached gh file with geometries internalized. It seems like the MEval component isn't returning the right outpout points in this case.Side note..it seems like MEval does not exist in rhinocommon and…See More

MeshEval Issue

Hi all,I am experiencing some issues with the MeshEval component.Firstly, when the corresponding mesh and parameters are plugged in, the points returned are not the same as the points input.Secondly, the color output is returning null.I have attached a sample of the script.Thanks a lot for helping!See More

"Hi. I'm not sure if it's close to what you are after, but this is one way to go. You'll need "Starling" topology remeshing tool and "Mesh Edit"+"Weaverbird" plug-ins."

tri to quad mesh

Hi all,I've been wandering around the discussion forum and some other places but can't seem to find a good place to start regarding the problem of remeshing a triangular mesh to a quadrilateral one. (it seems like something Daniel would have some idea of..)Any pointer or advice would be much appreciated!Attaching two mesh samples (generated from Delaunay Mesh and MeshMachine)..Thanks a lot and best,TimSee More

"Hi All, Might there be an example of dynamic remshing based on an image (as a map) For example, on a b/w image and the mesh density is based on the brightness? Thanks a lot!"

peter fotiadis replied to Timothy Tai's discussion pairs of closest points

Timothy Tai replied to Timothy Tai's discussion pairs of closest points
"Thanks a lot, Peter, this is great! Would you have any suggestion to do the closest pairs between the two lists? instead of only one single closest pair (for example, finding next closest pair until the smaller of the lists exhaust)? Thanks again!"
