In this video, I show the difference between deforming a mesh and deforming a surface in Grasshopper.
The workflow looks similar at first, but the logic is different. With meshes, you can keep the mesh network and move the vertices. With surfaces, you need to divide the surface, move the points, and then rebuild the surface from those points.
The main idea is simple:
- Meshes keep a network of vertices and faces
- Surfaces need to be rebuilt from modified points
- Data structure changes how points move
- Flatten can help create a smoother attractor-based result
