Can there be multiple conaffinity in a geom

Discussion in 'Modeling' started by Joy Chopra, Apr 2, 2018.

  1. I want to divide my model into 3 collision groups. Member of a particular group can collide with all other groups but not with a member of the same group. I know this is possible but am unable to do it. Please help with an example on how this can be achieved.

  2. I solved the problem using the Selection rules in Collision Detection section in Computation.
    Contype and conaffinity can be set in incremental way like this
    <geom name="geom1" contype="1" conaffinity="0"/>
    <geom name="geom2" contype="2" conaffinity="1"/>
    <geom name="geom3" contype="4" conaffinity="3"/>
    Earlier I did not realised the boolean and (&) in contype filtering and thought it was strictly based on equality.
