piplineViewer is PERT task viewer developed by Walt Disney Animation Studios for displaying shotgun tasks in a PERT graph view.
The pipelineViewer.py a Shotgun Action Menu item. It is being deployed on an Apache server with mod_python installed.
pipelineViewer is built in python and uses pydot to product the PERT graphic image. pydot is a python API over graphviz, so you will need graphviz as well as pyparsing python modules. You can find pydot at http://code.google.com/p/pydot/
To create the menu item, the normal Shotgun API can be used to create the action item.
For instance:
sg = shotgun(.....)
data = {
"title": "Pipeline View",
"url": "
You will need to provide your shotgun server, script and key parameters. We also use python logging services, you might need to adjust accordingly
