Reaction: A Survey of Algorithms for Volume Visualization

The author starts off by defining volume visualization and then introduces the reader to the background essential for visualizing volume. The datasets and the characteristics of volume like the cells, voxels, grids and lattices are explained.Two main categories of volume visualizing algorithms, DVR and SF and the different algorithms in these categories like Splatting, Ray casting,Marching cubes etc have been documented.

There were several concepts such as the depth fog attenuation, depth brightness attenuation in 'Viewing and Shading' section which I did not understand but overall the paper was definitely helpful in understanding the methods, complexities and challenges involved in volume visualization. The paper also gave a succinct description of the marching cubes algorithm.
