%description
The Vascular Modeling Toolkit (VMTK) is a collection of libraries and tools
for 3D reconstruction, geometric analysis, mesh generation, and surface data
analysis for image-based modeling of blood vessels.

VMTK provides tools for centerline extraction, branch geometry computation,
bifurcation analysis, vessel segmentation (level sets, active contours, fast
marching), and surface parameterization. It includes both C++ libraries with
Python bindings and high-level Python scripts for vascular analysis workflows.

Includes bundled TetGen 1.4.3 for tetrahedral mesh generation.
