Some examples:
The principles of the tool are:- all nodes are located on a ray through the point in the direction of the normal- the distance from input surface to pq mesh is adjustable- two of the edges are controlled by the graph-mapper![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiv5GAq1N1XjVdRjBOsl53-HCsun-MU7iSz8hNc24KSkhyphenhyphenbudwOG7ZeLV65imabPT1U4Efj90e4ozI1J5LBNGP_9kgKB1TuZtMa28QAe6UEx92TojMOG-m3dfCcnHN7RrSZvkkni3k-5znl/s400/Pic1.jpg)
A parametric tool for the design of planar quadliteral meshes based on uv-grid and normal directions of a design-driving NURBS surface.
The glazed freeform grid shell of the hippo house in the berlin zoo, has been designed by Schlaich, Bergerman + Partner. It consists of planar quadliterals, the geometry is based on a translational surface.
In this paper, a comprehensive discussion about geometric aspects of surface tesselation, by H.Pottmann et. al., can be found. A direct parametric approach, developed by Gehry Partners and Schlaich, Bergemann & Partners is described in this paper.
