When you watch it like that does the 8 not seem to change direction ? If so only a dbl kiss would cause that.Food for thought:
Running original on full screen at .25 speed, it appears to me that the cue ball hits the 8 further back, with less arc than the Virtual Pool example, and the cue ball almost, or does, contact cloth and the 8 simultaneously. Further, in the Virtual Pool example, the cue ball dies at point of impact with the 8 and does not track off to the right as shown in the original.
Is the accuracy of the Virtual Pool program such that we should expect to see the same post-strike track to the right if all variables (arc, point of impact, etc.) are the same as original?
Bob is pretty good at showing examples using virtual pool (4?). He believes it presents very realistic results and if it is good enough for him it is damn sure good enough for me
