It is possible, to create a mesh only with its vertex positions?
I do not have any other information about this mesh except maybe vertex and triangle count.
Thanks in advance.
If you only have vertex positions without any topological information (number of faces doesn’t help too much – it doesn’t tell you which vertices those faces are made up from), then you’re looking into the topic of “point cloud meshing” (good for a google search, as is “delaunay triangulation” – a specific implementation, and probably “level-set” as well).
Suffice to say that the code involved is fairly complex, especially if the point cloud has concave areas.
One simplistic method of meshing a point cloud, as long as point density is high, is to metaball every point. It won’t give you a correct mesh, but it can give you a rough starting point for proper meshing.
The best thing that I could come up with it was a piece by piece method. Grab a bunch of verts as planer as possible and use the 2D viewport positions to sort them and build a mesh. I never implimented it but I figure you could start slapping bits together at least. Grab a bunch of points align the viewport to them and hit go. It would sort them in to rows and columns and then build a mesh.
Thanks for your replies.
thats to bad, never thought about some topological informations. But it’s clear.
