Sierpinsky Triangles subdivision ( wbSierpinskyTriangle).

Caps the remaining hole with Sierpinski triangles. Places a new face departing from the middle of each original face edge. Split mesh with inner face ( wbSplitPolygons). The resulting mesh always consists of triangular faces. Calculates the type of mesh-based recursive subdivision described by Charles Loop, at first in his Mathematics thesis in 1987. It is topologically equivalent to the Catmull-Clark subdivision. Calculates a new mesh, which is formed of only quads and generally appears similar to the old one, except that it is welded. The resulting mesh always consists of quadrilaterals. Calculates the type of mesh-based recursive subdivision described by Edwin Catmull and Jim Clark, at first in 1978.

Download Weaverbird for Rhino 4+5 Works only in Rhino 4+5 and Grasshopper 0.9.gh file and Rhino will use the “Package Manager” to install Weaverbird. Download Weaverbird for Rhino 6+7 Open this.Instead of doing the work repeatedly, or sometimes using complicated scripts, this plug-in reconstructs the shape, subdivides any mesh, even made by polylines, and helps preparing for fabrication. Weaverbird is a topological modeler that contains many of the known subdivision and transformation operators, readily usable by designers.
