  1. Hi, I have a case where I have, lets say an object which comes from bulelt sim, with v and w. Based on that object, I want to drive another bullet sim, updating v and w, so the rest would be calculated by bulllet sim. In the scene I attached it works pretty much, except it flips at some point. I understand that there should be some catches on quaternions. I suppose, there should be some sort of angle check and etc, but can't make it work... update_angularv.hip
  2. L-System Pivot

    Hello, Does anyone know a way to get the pivot point of each prim from an L-System? I'd like to use this for animating bends and rotations but I'm not sure how I would go about it. Logically I need to find the nearest point on the previous gen to the 0 point of each primitive but it must also take into account the transforms of the previous gens too. I looked in to matt estela's rotation matrices but this doesn't account for the previous gen's transforms. Any help greatly appreciated. http://www.tokeru.com/cgwiki/index.php?title=HoudiniVex#Rotate_prims_around_an_edge.2C_alternate_version
