hatrick Posted January 5, 2009 Share Posted January 5, 2009 hi, i m new to dynamics in houdini ... currently i try to figure out a simple magnetic effect between 2 objects.... 2 RBD's (spheres) on a groundplane, one of them pushed closer to the other by little velocity... the other one should behave magnetic and force the speed of the pushed sphere when coming closer and holding it after impact .... Simple ?! two magnetic spheres sorry for my english hope you can help me out greets HT Quote Link to comment Share on other sites More sharing options...
michael Posted January 5, 2009 Share Posted January 5, 2009 you might try POPs instead... check out some of the example files on the attractor POP help card Quote Link to comment Share on other sites More sharing options...
hatrick Posted January 5, 2009 Author Share Posted January 5, 2009 ill search there... but 1 thing the spheres should behave like dynamic objects ... for example roling caused by friction, boucing off the other spheres a little before being stitched aso.... is that possible with pop`s? is it possible to combine networks in such a specific way ? thx Quote Link to comment Share on other sites More sharing options...
stevenong Posted January 5, 2009 Share Posted January 5, 2009 Hi, This old Katamari Challange should provide you with a solution. Cheers! steven Quote Link to comment Share on other sites More sharing options...
hatrick Posted January 5, 2009 Author Share Posted January 5, 2009 hm thx for that ... interesting stuff but i don`t think it`s the right way for me .... the perfekt thing would be a simple gravityforce but omidirectional. for example one point as a child of a RBD ... the center of my sphere is it posible to manipulate the standard gravityforcenode?

stevenong Posted January 6, 2009 Share Posted January 6, 2009 This thread might give you some ideas. Also, check out the following example using the Help Browser: http://localhost:48626/examples/nodes/dop/...ithrbdcollision I think a combination of all the above should let you do what you want. When you get it working, please show it to us. Cheers! steven Quote Link to comment Share on other sites More sharing options...
hatrick Posted January 6, 2009 Author Share Posted January 6, 2009 thx for help ... ill do so ... could take some time for a bloody newby greets Quote Link to comment Share on other sites More sharing options...
stevenong Posted January 6, 2009 Share Posted January 6, 2009 If I have time later, I'll try to set something up. In the meantime, you might want to look into the SOP Solver as well. Cheers! steven Quote Link to comment Share on other sites More sharing options...
hatrick Posted January 8, 2009 Author Share Posted January 8, 2009 hey.... i tried to rebuild the example files from the thread above.... little to much for me to follow another pont is that the force in there is not object centric ..? may ill spend some time with more basic setups... thx for your help Quote Link to comment Share on other sites More sharing options...
Allegro Posted January 8, 2009 Share Posted January 8, 2009 I like the magnet force dop. Quote Link to comment Share on other sites More sharing options...
stevenong Posted January 8, 2009 Share Posted January 8, 2009 I like the magnet force dop. Please try Allegro's suggestion first then. Cheers! steven Quote Link to comment Share on other sites More sharing options...
stevenong Posted January 9, 2009 Share Posted January 9, 2009 Hi, I have a simple setup using the Magnet Force DOP. I've made comments on those nodes with their names in blue. MMB on each node to read them. Cheers! steven magnet_force.zip Quote Link to comment Share on other sites More sharing options...
