This one happens to have dynamic properties wrt the actual field properties. The dynamic aspect is used for real time animation: http://funwithfractals.atspace.cc/ct_gfield_test/ct_3dgfield_anime_test After clicking on the link above, you should see a rotating unit cube in white, along with two field line “clusters” in red and yellow. The lines should be animating back and forth between independently animated repelling and attracting mass points that are not visible, but you can see the lines point toward them when there are in attraction mode. FWIW, they are at points (-1.0, 0.0, 0.0), and (1.0, 0.0, 0.0) respectively. The actual field lines animate along the y axis in the middle of the unit cube. Does this work for you? BTW, sorry for asking everybody to act as “testers”, however, I really appreciate any feedback: good or bad. If you have any problems, I would love to hear about them. Thank you all! :^) One unfortunate point wrt the current crude, kind of crappy code... I made the dimensions of the WebGL canvas small, and this is hard coded. BAD! The end result of these experiments is going to be controlled by a GUI. ;^)
