Scripting – Finding the objects in different SimulationEnvironments


Here’s a script that goes through the SimulationEnvironments of a scene and find the 3d objects in each SimulationEnvironment. This snippet builds a dictionary of 3d objects, indexed by simulation environment.

from siutils import si
si = si()					# win32com.client.Dispatch('XSI.Application')
from siutils import log		# LogMessage
from siutils import disp	# win32com.client.Dispatch
from siutils import C		# win32com.client.constants

from xml.etree import ElementTree as ET

# Use a dictionary to store the 3d objects keyed by Environmen
dict = {}
for e in si.ActiveProject2.ActiveScene.SimulationEnvironments:
	stack = XSIUtils.DataRepository.GetConnectionStackInfo( e.SimulationTimeControl )
	xmlRoot = ET.fromstring( stack )
	for xmlConnections in xmlRoot.findall('connection'):
		o = xmlConnections.find( 'object' )
		dict[ si.Dictionary.GetObject( o.text ).Parent3DObject.FullName ] = e.FullName
		
log( "3DObjects and their SimulationEnvironments" )
for key, value in dict.items():
	log( "\t%s, %s" % (key,value) )

log( "" )

log( "SimulationEnvironments and 3DObjects" )
dictvals = set( dict.values() )
for env in dictvals:
	log( "\t%s" % env )
	list = [k for k, v in dict.iteritems() if v == env]
	for o in list:
		log( "\t\t%s" % o )

Here’s some sample output from the script:

# INFO : 3DObjects and their SimulationEnvironments
# INFO : 	pointcloud1, Environments.Environment
# INFO : 	Point_cloud_chaser.pointcloud2, Environments.Environment1
# INFO : 	grid, Environments.Environment
