Find a moderately sized data set of interest to you on the internet that contains three-dimensional scalar data. Using the routines developed in the previous exercises, visualize the data using isosurfaces and again using volume rendering. Compare the two visualizations and list the advantages and disadvantages of displaying the data in each format. Also explore the different possible schemes for dealing with multiple voxel intersections in volume rendering (e.g., valueaveraging, min-max values).
