Using the Node View
The Node View is the heart of Shake’s graphical
compositing interface. This chapter covers all aspects of
navigating, customizing, and organizing nodes using this
powerful tool.
About Node-Based Compositing
The Node View in Shake displays all of the nodes that are used in a script. This
amalgamation of all the nodes used in a script is referred to as the node tree.
Each node in the tree performs a specific function, and is connected to other nodes by
lines referred to as noodles. The noodles that stretch between each node represent the
flow of image data from node to node.
Noodles are connected to input knots on each node. The output knot of one node is
usually attached to the input knot of the next node down in the node tree. In this way,
image data is passed top-down, from one node to the next. Thus, the image is
modified bit by bit until the final result is achieved.
