Visualization of level-of-detail meshes on the GPU
Extensive research has been carried out in multiresolution
models for many decades. The tendency in recent
years has been to harness the potential of GPUs to
perform the level-of-detail extraction on graphics hardware.
The aim of this work is to present a new level-of-detail
scheme based on triangles which is both simple and efficient.
In this approach, the extraction process updates vertices
instead of indices, thus providing a perfect framework
for adapting the algorithms to work completely on GPU
shaders. One of the key aspects of our proposal is the need
for just a single rendering pass in order to obtain the desired
geometry.Moreover, coherence among the different approximations
is maximized by means of a symmetric extraction
algorithm, which performs the same process when refining
and coarsening the mesh. Lastly, we also introduce different
uses of the scheme to offer continuous and view-dependent
resolution
