BackTrack/Win Screen Shots
Shown are the Top, Side and End views of the virtual string patterns resulting from two blows to blood sources. This was done in a laboratory in Edmonton at the October 2003 Math/Physics Advanced BPA Course as part of the training in the use of BackTrack. CPx, CPy and CPz are the coordinates of the locations of the blows as computed by BackTrack/Win and depicted as red crosses.
The image inserted into the side view diagram shows a photo of the experimental setup which has a box-like structure sitting on the floor in the corner where the main wall meets the right wall. The image editing program Paint Shop Pro was used to depict the box colored grey. The letters T, S and E stand for the top, side and end surfaces of the box. The rest of the diagrams were produced by the BackTrack/Win program.
The computed CP values are compared with the true values in the tables below.
