This example shows how to load a hip file from a Python shell and inspect its contents.
This example loops through all the object in
/obj and prints out the positions of each of the points in the object.
hou.hipFile.load("file_to_load.hip") for object in hou.node("/obj").children(): print "Points in", object.path() for point in object.displayNode().geometry().points(): print point.position() print
Running outside out Houdini
You can run this example outside of Houdini or Hython (that is, in a standard Python environment) if you first add
hou to the Python path and import it (note that this will still use a Houdini license).
import sys, os # Adjust sys.path so it contains $HFS/houdini/pythonX.Xlibs. Then we can # safely import the hou module. Importing this module will bring a Houdini # session into the Python interpreter. sys.path.append( os.environ['HFS'] + "/houdini/python%d.%dlibs" % sys.version_info[:2] ) import hou
If you want to use
hou as part of a larger general Python application, and you want to take up a license for the minimum time possible, you can release the license when you're done with it using hou.releaseLicense():
# Release the Houdini Batch license. If this script accesses the hou # module again it will reacquire the license automatically. hou.releaseLicense()
