sfennell Posted November 7, 2005 Share Posted November 7, 2005 Hi, new to houdini and I'm interested in trying to simulate denting metal, much like a car crash, and was wondering if Dops could do this? I was looking at the POP shape match example which sort of simulates a soft body in a dop network but I couldn't get the geometry to retain each of its shape changes. Does anyone have any ideas on how to acheive this sort of effect? I'd like to be able to simulate the gross motion of the vehicle, and then apply denting and crushing shape deformations based on that DOP simulation. Is it possible to do all in DOPS or will I have to combine techniques? Quote Link to comment Share on other sites More sharing options...
aracid Posted November 7, 2005 Share Posted November 7, 2005 hey sfennell i dont know if this will help but take a look at the example scene files under the sopsolver in DOPS, its amazing how u can deform RBDs'. hope this helps all the best aracid Quote Link to comment Share on other sites More sharing options...
sibarrick Posted November 7, 2005 Share Posted November 7, 2005 There's a sop deformer example somewhere that shows a torus getting dented by impacts..... of course rather unhelpfully I don't know off the top of my head where it is. But look up the sop deformer and look to see if there are examples. Quote Link to comment Share on other sites More sharing options...
sfennell Posted November 8, 2005 Author Share Posted November 8, 2005 I investigated the sop deformer example and modified it so that the torus is falling on a ground plane and the metaballs and magnets are generated at the collision impact positions. This does in fact give me denting deformations during the dop simulation, although sometimes it creates strange dents. I was wondering if there is a more controlable way to deform the geometry other than metaballs? Occasionally the geometry tends to deform in slightly unpredictable ways, stretching out in some collisions instead of denting in. Does anyone know a technique to help achieve more predictable denting deformations? Quote Link to comment Share on other sites More sharing options...

Couldn't get it to work though. But I really didn't put too much time into it, give it a go you might be able to get it working. Quote Link to comment Share on other sites More sharing options...
