Dopnet Default Data

[sfennell]

In all of the dop examples there are expressions such as dopfield() referencing certain dop data such as Position or Impulse, even Geometry is data that can be referenced in commands and operators. However, I can't seem to find reference to any of these default Data sets in the documentation. Is there a way to find out what default Data is attached to rbd objects?

Use the Details View pane to examine the data that gets added for each DOP node.

Yep. The tree view you get in the Details View pane for a DOP simulation an almost exact representation of the information you can extract from a DOP simulation using the dop* expressions. IT"s not that hard to write a script that prints out almost all of the exact same information you getin that tree. Geometry data is special in that it has a little bit of information available through dopfield expressions (such as the source SOP). But to get most information from Geometry data, you should use the expressions you use to extract geometry information from SOPs. Any expression which takes a SOP node (such as point, prim, etc) will accept a path to DOP Geometry data instead. So you can do stuff like:

point("/obj/dopnet1:rbd_object1/Geometry", 0, "P", 0)

of course! that makes sense. Thanks to both of you.
