CSN0309 Posted July 19, 2011 Share Posted July 19, 2011 Hi~guys I got a question here, should be very simple, but i didn't get through it.... I have put a moving metaball on a deformed surface, and use rippleobject node and ripplesolver node inside the DOP network to sim water ripple, so my question, how can i group those points that only effected by ripplesolver on this deformed surface? i only want to group the area that influenced by dynamics simulation....any ideas????? thanks in advance.DOP_group_test.hipnc Thanks Quote Link to comment Share on other sites More sharing options...
symek Posted July 19, 2011 Share Posted July 19, 2011 You could, for example, compare these two geometries (rest one and the one after ripple solver) by subtracting point's positions or velocities. This would give you timeless difference though. Doing the same in Sop Solver would accumulate results (so keeping grouped points across time). Then group by attribute or similar. See example. cheers, skk. DOP_group_test_skk.hipnc Quote Link to comment Share on other sites More sharing options...
CSN0309 Posted July 19, 2011 Author Share Posted July 19, 2011 Thank you so much~ SYmek~ thanks, before your example, i didn't know i can import attribute into VOP and do a comparison.. thanks Quote Link to comment Share on other sites More sharing options...
