my fault actually need to write you more tools for visualization.

Problem is we are used to 1D and 2D functions and image processing, so when we are given volumetric data find it hard to even start looking at them. It is an educational situation, hopefully John will help us to overcome.

For that matter, I am making these videos and CDFs so we could get use to volumetric data and run the algorithms on volumes vs. 1D or 2D setups.
