delaunay triangulation on a Ring Shape ( Or others complex solids shapes )

Hi Everybody

I'm playing with Delaunay Triangulations.

I've got a nice result working with a box ... but on the next step I would like to apply this triangulation on a ring shape ( or others interesting and complex shapes ).

How can I do it ?

I attach the def and a picture just to show you What I've got

Thank you in advance

Hi.

This one is an example using "MeshMachine" in Kangaroo plug-in. Best.

Thank you ... it work pretty well ... but what about if I want to use a prebuilded ring shape ...and what about if I want to use others freeform complex shape that I have already built ?

The other problem si that the triangulations are constant .. not random as I did in my definition. I would like to have something like my result but applied on a ring shape or other freeform complex shapes

Get this as well.

Input your new brep into brep container and generate mesh using MeshMaching with adjusting target edge length & reset toggle.

And then press toggle switch to "True" to get your delanuay triangulation.

Thank you .... this is interesting .....

Is it possible to have a random triangulations ? I mean ... now the triangles are in row and every triangle has the same area of the other. I would like to have a random size triangulation

Yeah it work nicely .... but What I was trying to do it was to use a complex shape as a container of the faceting. If you see on my def the box geometry contain the triangulation itself ... in your definition the triangulation is all around the shape.

Do you think is it possible to work in the way I need ?
