| Nov 17, 2012 at 15:04 | comment | added | Mikael Högström | So what about the brick wall? It isn't very elastic but still a rubber ball will bounce off it whith a high COR. It's not so much that I want a perfect simulation, rather something very simple to maintain. When I add a new material in an xml-file it's nice if I can just give it some values (like restitution, elasticity, hardness etc) and have everything "just work" rather than a table where all materials will need to have entries changed if another one is added. Very good answer though, I'll probably go with something like this! | |

I suppose that if you really want to simulate rather than approximate you could calculate forces and use tables of yield strength... PS I've e-mailed the author of that thesis to notify him of the broken links. | |

Sand would have high weight being soft and a brick wall having a low weight being hard? | |
