ShapeWorksStudio: Particle-based Shape Correspondence and Visualization Software: PDF
This hands-on tutorial overviews the technical background of particle-based shape modeling implemented as the backbone of ShapeWorks and the associated user-friendly graphical interface ShapeworksStudio. Both software packages are open-source distributions of a new method for constructing compact statistical point-based models of ensembles of similar shapes that does not rely on any specific surface parameterization. It is developed by the NIH Center for Integrative Biomedical Computing at the University of Utah Scientific Computing and Imaging (SCI) Institute.
