Planar Quad Mesh Design Pt. 2

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

Planar Quad Mesh Design Pt. 1

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.

Advances in Architectural Geometry 2010

Since Friday, the proceedings volume of the Advances in Architectural Geometry Conference 2010 is available. The book is published by Springer Verlag.

The Bubble Room

An underwater dome, shaped by the buoyancy force of an oxygen bubble. This beautiful piece of subaqueous architecture has been build by Jordan Needham and his familiy at the bottom of a Nevada mountain lake. Found on the boingboing blog.


The pictures are screenshots from the movie below.

Creative Data Symposium

On 24.8.2010, I will give a lecture titled The Geometry of Forces at the creative data symposium at CITA, Royal Danish Academy of Fine Arts.

Parametric Paperstrip

This parametric model represents the geometry of a twisted straight paperstrip. Length, width, and twist are adjustable.


Some example strips. By definition these surfaces are developable.

Download the definition here. Another interesting approach has been done by Daniel Piker.

Finds from the Seaside

On a trip to the seaside near Istanbul, Turkey I found some beautiful biological examples.

A nice example of an algae, ulva lactuca.


An eroded rabbit's skull from behind.


A wing of an insect, probably a cricket.
