VESPA: VTK Enhanced with Surface Processing Algorithms

Abstract

This work introduces the VESPA project, a bridge between geometry processing with the Computational Geometry Algorithms Library (CGAL) and scientific visualization with the Visualization Tool Kit (VTK) and ParaView. After a brief description of these tools, we motivate the use of VESPA through the example of a full processing pipeline detailing the construction of a mold from an initial 3D surface model. This paper illustrates the use of several robust geometry operations as well as the benefits of added interactivity and visualization. As an open source project, VESPA is already publicly available and open to contributions.
