GTL - Geometric Template Library

The GTL (Geometric Template Library) is a template-based library providing a framework for handling simplicial complexes in arbitrary dimensions. Triangle meshes as well as tetrahedral meshes can be stored in this data structure in a consistent way. Besides the general data structure, different algorithms are integrated for fast rendering of tetrahedral meshes based on a novel interface extraction algorithm, volumetric cutting (plane and shape).

Features

• N-Mesh data structure consisting of N-Simplices and a vertex buffer
• Support for tetrahedral and triangle meshes
• Interface extraction for tetrahedral meshes
• Consistent volumetric cutting
  • Plane cutting for geometrically exact cuts
  • Shape cutting for cutting 3-meshes with 2-meshes
• Optimization algorithms for enhancing the mesh quality
• Some further data structures like: octree, kd-tree, binary tree
• Coin nodes for rendering the mesh in a scene-graph-based library using OpenGL
• All code is template-based and allows therefore generic implementation

A detail description will be provided soon.
