The objective of this project is to investigate mathematical models
for point-based surface representations which are useful for 3D geometry
processing and interactive modeling. Our processing and modeling tools
work directly on the acquired point cloud, avoiding the reconstruction
of the surface. We developed a set of algorithms for interactive shape
and appearance modeling which are available as OpenSource
(see Pointshop3D) including
painting, texturing, sculpting, filtering etc. Spectral decomposition
of the model supports effective filtering, resampling, power spectrum
analysis and local error control. Multi-scale methods are used for
robustly extracting features from an object. We researched different
surface simplification techniques such as clustering, iterative point-pair
contraction, and particle simulation. Exploiting the advantages of both implicit
and explicit representations, combined with a novel re-sampling algorithm,
allows interactive boolean operations for CSG and free form deformations.
Using a multi-scale surface representation, sophisticated editing
functionality at different approximation levels is provided. Finally,
an interactive 3D painting system allows intuitive appearance editing
of a point-sampled model using a haptics device.
