SQuadGen is a mesh generation utility that uses a cubed-sphere base mesh to generate quadrilateral meshes with user-specified enhancements. In order to determine where enhancement is desired, the user provides a PNG file which corresponds to a latitude-longitude grid. Raster values with higher brightness (whiter values) are tagged for refinement. The algorithm uses a basic paving technique and supports two paving stencil types: Low-connectivity (LOWCONN) and CUBIT-type transition regions.
