Delaunay & Convex-Hull real-time vs precalculations ?

Hi there,

I need to alter meshes by using some transformations.
Delaunay & Convex-Hull are targeted for the main interesting leads / ways.

Ideal situations:
I load meshes from obj (jit.gl.model), my system processes them by transforming dots/triangles and whatever and render the result.

That way, I could change Delaunay accuracy and way of working in real time too.

Same reasoning for Convex-Hull (except that one should feed a new mesh overlayed / blended to the original one)

But I'm afraid of performance. Doing it on GPU is not easy.
So I'm thinking about precalculating that in meshlab or whatever and load/merge meshes in Max.

Any leads/ways/ best practice ?

Thanks a lot

Julien
