 abstract = { Progress in numerical modeling of physical processes has opened the way to new types of simulation
grids made of complex polyhedral cells. Visualizing scalar fields on such grids without
increasing the number of cells calls for a generalization of existing isosurface extraction algorithms.
We present a method to efficiently tessellate on a GPU tetrahedral, hexahedral and hybrid grids.
This method also works for strongly heterogeneous grids, with arbitrary polyhedral cells. It avoids
data redundancy and processes efficiently large grids made of millions of cells. To achieve this,
textures are used to store most of the needed data and are accessed through vertex texture lookup
in the vertex shading unit of modern graphics cards. Results show that this method is faster than
the same CPU-based extraction. In the case of tetrahedral grids, our method is complementary
with previous approaches based on GPU registers: it is less efficient for small grids, but allows the
storage of millions-tetrahedra grids in graphics memory, which was impossible with previous works. },
