Hello,
I’ve been working on developing a tool or at least a new approach to concept modeling for designers, but I’m getting a bit stuck, due to the current limits of my understanding of grasshopper.
Intent:
Create a definition that takes a collection of geometry (curves, and meshes in particular) and wraps them an orderly and aesthetic mesh, similar to a cocoon or what a silk work might do. (Curves do not have to meet at all.)
Example use case:
A car designer creates key construction curves as a gesture and the definition is able to extrapolate a preliminary car body volume. later additions to the definition would allow for minimal surface and physics-based mesh actions (kangaroo, millipede etc.) on selected regions to create relaxation or convex or concave surfaces.
Ideally, the solution would be flexible enough to work for concepting anything from a car, to a shoe, to a building or a boat.
Issue:
3D convex hull reliably creates a volume, but misses the concave details. Ball pivot and Alphashapes can create something that begins to look like what I’m trying to achieve, but only if the sphere radius is carefully controlled in relation to the gaps between curves, so doesn’t make for a very flexible solution, and still misses some of the nuance, because of the larger sphere radius required to span larger gaps.
(FYI, I’ve been using quad re-meshing as a way to get a more inform output after the initial shape is made)
Question:
Can anyone help me with the following?
-Improve the approach in the attached file to be more flexible and creating a more smooth, yet orderly mesh output.
-recommend a better approach.
-point me to relevant topics or papers that might give me a deeper understanding of relevant topics?
-let me know if I need to learn python to make real headway with this.
many thanks for any help you can offer!
Nate
