Fast Voxel Traversal Algorithm Over Spherical Coordinate Grid

About

This project extends the yt open-source data analysis and visualization package, providing an enhanced, integrated user interface for data exploration and enabling the visualization of physical data that comes from non-cartesian grids. Currently, yt implements a fast voxel traversal over a cartesian coordinate grid. The objective is to develop a fast voxel traversal over a spherical coordinate grid, based on ideas from Amanatides and Woo’s seminal paper on fast voxel traversal for ray tracing.
