REQ - Drape Points?
-
Is there a ruby that exist which will drape a grid of construction points over a mesh and essentially create a points cage of the mesh? I'm thinking along the lines of using it for a retopology method, whereas you can create a type of mold out of construction points for reference when adding details within a topology.
It would require the user to define the spacing for the grid of points and then draw it out on the same plane as the mesh. Then lift the grid of points above the mesh and hit drape. The points would fall down in a "drop at intersection" manner and stick to where they intersect with the mesh. You would then have a mold of the mesh to work with. I believe there is another ruby that will also create a mesh from the points after they are created.
I hope that makes sense. Not really sure how to draw an example. Is this a possibility?

You pretty much just described the process that goes on behind the scenes of Didier's Terrain Reshaper plugin. Are you thinking of something different?

If you don't mind an irregular grid of cpoints then something that puts cpoints at the mesh's edge ends would work.
If you want a regular grid then its a bit more complicated... you select the mesh and run the tool, the mesh.max.x/y and min.x/y determine the overall size of the grid group; you are asked for grid size, then a grouped grid of cpoints to a suitable x/y size is made above the mesh.bounds.maz.z, then each cpoint in turn is ray_tested in -ve z till the cpoint hits a mesh face/edge and the cpoint is 'dropped' to suit. Any cpoint outside of the mesh drop-zone (i.e. ray_test fails) would drop to mesh.bounds.min.z ...
