ICENode
v7.0
The ICENode class represents a built-in or custom effect node in the Softimage ICE graph. ICENodes can be assembled
in sub-graphs called compound nodes, which are represented as ICECompoundNode objects.
The ICENode class API is convenient for accessing the different components of an effect node such as ports,
port groups and port group instances. The node ports are organized in groups similar to the Softimage operator
Ports, where groups are logical groupings of multiple port connections. Other ICENode objects
can connect to an ICENode object via its ports represented as ICENodeInputPort and
ICENodeOutputPort.
