how to get hou.Geometry from SIM_DopData

[rayman]

Is it possible?

I want to get gluenetwork solved geometry from relationships data.

It is possible to get this data from DOP to SOP and then to get geometry from there but I`m wondering if there is simpler/faster way?

thanks

Unfortunately it's not possible to extract geometry data as hou.Geometry from raw DOPs data.

Thank you!

Found it!

Just copy SIM_GeometryCopy data to empty object and then access this object.

def createGlueData():
	obj = hou.node('.').simulation().createObject("glueGeo",1)
	data = hou.node('.').simulation().findRelationship('glueNet').findSubData('gluenetwork/Geometry')
	obj.attachSubData(data,"Geometry")[/CODE]

[b]attachSubData[/b]

Make existing data become subdata of this data. Houdini does not create a duplicate of the data. Instead, the data’s parent(s) and this data will both refer to the same instance of subdata. You would call this method from a script solver DOP.

I`m wondering why attaching data to existing objects does not share the same geometry data (I have to attach it every frame otherwise it doesn`t update).
