Looking for a variation of a drape plugin

chanz

Hi all.

I am not quite sure of the exact terminology or if something like this even exists yet.

I have some old meshes from an old game format. The ones I am looking at are terrain meshes. They were cut by a BSP tree, and therefore, some of the grids are a bit overly complex. I have tried mergine coplanar faces and still, it doesn't fix everything. I want to fix this by recreating them with the sandbox feature.

Here is a test case I set up:

What I need to happen, is for the sandbox terrain at the top to take on the shape of the terrain at the bottom without creating additional vertices (other than the squared being divided to create 2 triangles). The algorithm would do something like every index would go down and down until it intersected the mesh and then keep that height value.

Is such a thing possible? What is the term for it? Is there a plugin for this already? I tried the drape and super drape and they looked promising but not quite what I need. They add the detail to the sandbox mesh when I just want the height and not the additional vertex detail.

Thank you

One possible way:

create cpoints for all vertices from the top face (FredoTools)
drape them with the raytracer plugin (Thomthom)
Create triangualted mesh (TIGs triangulate points) or with Toposhaper (Fredo6)

Thanks for the response. My only question is whether the generated mesh will be able to be edited using the sandbox tools.

Yes it can! But the action Brush Tool Modeler is a "circle" that you can increase decrease!

Sandbox generated geometry is nothing special so every other geometry can be edited with the sandbox tools too.

Drop Vertices by TIG should work.

Thanks all! Both solutions worked but the drop vertices was very speedy. Thanks!
