Optimization of 3D Models for Fabrication (Henrik Zimmer)

Abstract
By combining geometric considerations with modern optimization methods
and computing power, the research area of Architectural Geometry strives
to bridge the gap between creative architectural freeform designs and
their efficient realization. In this talk, a set of novel optimization
approaches for dealing with three different architecturally motivated
optimization tasks is presented.

First, for enabling efficient (e.g., glass) panelings of tessellated
freeforms, a planarization technique is introduced. The formulation is
based on plane intersections, yielding planar panels by construction.
Furthermore, the method’s generality is demonstrated by application to
different architecturally inspired optimization tasks.

Then, for a new type of support structures, called point-folded
structures, an anti-diversification technique is developed for reducing
the number of geometrically different panels. By a problem-adapted
parametrization and search strategy, the shape redundancy can be reduced
by over 90% for various freeform designs, enabling significant
reductions of fabrication costs in practice.

Finally, for the still largely unexplored, high potential area of
constrained tessellation techniques, i.e., tessellation algorithms
restricted to using only structural elements from a predefined set, a
novel approach based on a commercially available construction system
(Zometool) is presented.
