ikarus Posted May 2, 2011 Share Posted May 2, 2011 What would be the easiest way to find the average velocity of a set of geometry and reference that in a parameter? eg basing emission rate off overall speed of the source thanks Quote Link to comment Share on other sites More sharing options...
graham Posted May 2, 2011 Share Posted May 2, 2011 I'd probably compute the velocity with a Trail Sop, then use an Attribute Promote SOP set to Average to convert it to a detail attribute which can then just be read into a parameter using a detail() expression.

That sounds good to me. To add to that, if you need it per object then use a for each SOP (and connectivity/partition if they are not already in groups).
