AMR Data in VTK - Nov '05

This was a project I did during my last semester at the University of Illinois as part of a graduate level Scientific Visualization class. AMR (Adaptive Mesh Refinement) data is represented as a heirarchy of grids of different resolutions. Many standard visualization algorithms exist for visualizing volume data stored as a uniform 3D grid, but it is more challenging to apply these algorithms when dealing with data at different resolutions. VTK (Visualization Toolkit) is one of the most common packages for doing Scientific Visualization but currently does not support AMR data. I used the VTK interface in c++ to extend this package to support rendering of AMR data and create visualizations such as seamless isosurface generation, slice planes, and various volume rendering techniques.
