GTS

About GTS.

The GNU Triangulated Surface Library (GTS) is an Open Source Free Software Library intended to provide a set of useful functions to deal with 3D surfaces meshed with interconnected triangles. A brief summary of its main features:

• Simple object-oriented structure giving easy access to topological properties.
• 2D dynamic Delaunay and constrained Delaunay triangulations.
• Robust geometric predicates (orientation, in circle) using fast adaptive floating point arithmetic.
• Robust set operations on surfaces (union, intersection, difference).
• Surface refinement and coarsening (multiresolution models).
• Dynamic view-independent continuous level-of-detail.
• Preliminary support for view-dependent level-of-detail.
• Bounding-boxes trees and Kd-trees for efficient point location and collision/intersection detection.
• Graph operations: traversal, graph partitioning.
• Metric operations (area, volume, curvature ...).
• Triangle strips generation for fast rendering.

Using GTS on Stallo:

GTS is installed under:

/global/apps/gts/<release-date>/

To be able to use GTS you must load the GTS module on Stallo:

module load gts

You must run this command before you try to link you application with this library.
And you may have to add this command after the PBS-stuff and before the executable stuff in your job script.
