I was browsing trough Grasshopperdocs just now looking for mesh tools that could help me retopologise and model a terrain based on an input surface/ mesh and a series of curves.
I have both a surface to start of with and have are plenty of methods to do remeshing to tris and/ or quads.
I am specifically looking to create clean roads within the mesh by split the mesh at road outlines curves, which I want to extrude down and bridge to create sidewalks and the road surfaces themselves.
So I am looking for components to:
- Extrude polyline segments as quads (MeshPlus? or Purfferfish’s Parameter Extrude Mesh)
- Split a mesh based on an edgeloop that is closes to a curve
- Bridge edgeloops with a segment count (MeshPlus’ Mesh loft?, FRoGH Mesh Bridge or Pufferfish’s Parameter Loft Mesh).
- Offset an edgeloop in the XY plane
- Chamfer/ fillet edgeloops (Weaverbird?)
It appears that I need to do a lot of deconstructing and reconstructing to get the other tools (2, 4), but are there any tools that allow me to do these things more easily? I am specifically thinking of inputting a curve that retrieves the closes edgeloop > execute modeling command > output new mesh.
That is because I already have the curves and surface in my current project.
