NOTE Unless otherwise specified, the term node and tool node are
interchangeable throughout this guide.
When you create a composition by importing media, the composition contains
one input node (which points to the media you imported) and one output
node. You then build the dependency graph by adding tool nodes. For more
detailed information on the different types of nodes, see
Node Overview on
page 52.
You can set the direction in which processing proceeds in the User Preferences
Creative tab. For 2D workflows, you can build the dependency graph
left-to-right or top-down direction. For 3D workflfows, you can build the
dependency graph in a left-to-right or bottom-top direction -- see
Setting User
Preferences
on page 168.
A dependency graph with left-to-right flow.
A dependency graph with a top-down flow.
NOTE Nodes do not necessarily have to be connected. For example, you can
create branches that you connect or disconnect to experiment with different
scenarios.
