Grasshopper

algorithmic modeling for Rhino

Information

Leopard

Leopard is an open source mesh processing solution for grasshopper that allows users to interact with rhino geometry and create customised mesh shapes. By selecting Mesh vertices, edges and faces, users have more freedom to edit meshes intuitively and use different subdivision schemes to selectively choose multiple areas to fix.

Mesh data using Plankton for internal processing.

Leopard is still in the very early development stage, so please use it for your own risk and we welcome any feedback, discussion or insight you may provide.

Hi Christian, thanks for the suggestion. I think it is a good idea for all (Faces, Vertices, Edges)Neighbours components to have indices outputs as well. I can add this output to components in the next version. :)

Hi Gene, a small suggestion it would be nice if the FaceNeigbours component would also output indices of the neighboring faces not only polylines. Thanks!

Yeah, I think GitHub or Plankton forum is a right place to discuss this topic. :) 

Comment by John on January 30, 2017 at 7:18

Yes but if I want to input polylines.

Then I cull them. Probably faces indices also are not working as they are indexed by vertices. I ll try to ask on github if there is an option to weld plankton mesh.

Hi Tom, 

Instead of using polylines, Plankton mesh can be directly created from mesh. In C#, Plankton library has PlanktonMesh.ToRhinoMesh() method that you can use. 

About how to identify duplicated edges and vertices, you can refer to this discussion:Duplicate Point Identification

While using Leopard, you don't have to worry about if the input is Plankton mesh or not. All the input can be a single mesh, a list of mesh or DataTree mesh. 

Cheers, 

Gene

I have general question about plankton.

If you create plankton from discrete polylines.

Is it possible to weld it? So that all coincident vertices and edges would be removed.

Daniel, thank you for your valuable advice. Regarding gha question, we are still waiting for food4Rhino's approval, so people will be able to download gha and example files soon.

About compiling path, I thought it wouldn't be a problem for developers to change their own path in compile events, but if people prefer me to delete it, I can also do it later. 

This is in the very early development stage, but our plugin already has some functionalities to subdivide but fix some vertices, edges or faces. We will definitely add more advanced features in the future version. (something like t-spline functions is one of our plans too.)

Comment by Daniel González Abalde on January 7, 2017 at 9:24

Thanks for the plugin :)
Your vs project has configured post-compilation events, which stores the .gha in a unique path of your computer. Then, for others, to compile the project, Project> Properties> Compile Events, and adjust the path by changing the username. Or removing the lines, I suppose. But for the general public, you should share the gha directly.

It would be nice to have tools like tsplines, for example, from a edge index and a normalized value, subdivide only that edge (and faces around). Or for the case of quadrangular meshes, an option to subdivide the entire row or column of the selected edge.
