This semester I've been taking a class in scientific visualization. It's pretty interesting and it covers a lot of techniques such as color visualization, human vision and color perception, contours, isosurfacing, volume rendering, flow visualization such as stream lines and stream surfaces and texture based methods.
There are good and bad parts to this course. The bad part is that it is a fairly new graduate course and has no prerequisites. The professor is just trying to build up interest in the course. This equates to us not actually coding the different algorithms, but using a visualization framework, VTK, and c++/java/python/tcl to implement the techniques. The good part is that this semester is one of the busiest I've had, so minimizing my work is a good thing :)
Now on to some pictures.
