Pattern from surface and features
How to obtain a structured quad-mesh pattern mapping a surface including optional point features on it
RV2pattern_from_features is based on the compas_singular package. For more information on the package, please check out its online documentation.
Using the RV2pattern_from_features command is a powerful and an effective way to generate quad mesh patterns from complex or irregular boundary conditions and point features, such as the British Museum Great Courtyard Roof.
This algorithm works for trimmed, planar, curved and non-heightfield NURBS surfaces, but not NURBS polysurfaces or meshes.
Following the boundary
The first example takes into account only the input surface to produce a pattern align with the boundaries. This aspect is important in funicular form finding in the case of non-supported boundaries.
With poles around point features
The second example also takes into account point features on the surface to include pole points in the pattern. The point features at the corner can integrate local concentration of thrust. The other point features can integrate point loads or nodal supports. All these aspects are important to design a suitable pattern for funicular form finding.
