| 04:57.39 | abhi2011 | hmm, so I am trying to figure out how to calculate the amount of force to be applied while simulating their fall from a height. |
| 04:57.50 | abhi2011 | here is the plan at the moment : https://docs.google.com/drawings/d/1Fp44t9AcZZurbNufXti64u-23CRjC49Z3r0WSmim5tU/edit?hl=en_GB |
| 04:58.07 | abhi2011 | so I plan to shoot rays in the overlap region |
| 04:58.39 | abhi2011 | and apply forces along the normals |
| 04:59.21 | abhi2011 | so for the box in the above figure, all the forces acting on it along the x-axis will cancel each other out |
| 04:59.39 | abhi2011 | and only the Z force will remain , pushing it up, |
| 05:00.25 | abhi2011 | this would be the case in the real world, with the reaction from the collision acting on the box to make it bounce on the GP(ground plane) |
| 05:02.31 | abhi2011 | however if I start summing the normals(encountered while shooting rays) for the box I end up with something like 4.9999 , 3.9999, 6.00002 |
| 05:02.57 | abhi2011 | which is not pointing along +ve z as one would expect |
| 05:03.47 | abhi2011 | So I will probably, ignore a direction which I have encountered before |
| 05:12.19 | abhi2011 | that will I will need to store normals and check every new normal generated , with the previous ones |
| 05:47.37 | abhi2011 | instead of investigating the surface of a primitive using rays and shooting rays in a direction opposite to surface normals, I can also apply forces in a direction opposite to the velocity, but that will probably not work in all cases |
