Interactive Rendering of Large Unstructured Grids Using Dynamic Level-of-Detail
We describe a new dynamic level-of-detail (LOD) technique that allows real-time rendering of large tetrahedral meshes. Unlike approaches that require hierarchies of tetrahedra, ou...

A Barotropic Global Ocean Model and its Parallel Implementation on Unstructured Grids
Unstructured grids can represent the complex geometry of the ocean basin with high delity. The lack of development tools supporting irregular grid problems discourages the use of ...
