Ganbar R. - NUKE 101. Professional Compositing and Visual Effects - 2011

GETTING STARTED WITH NUKE 7
Keyboard shortcuts in Nuke are location specific as well. Pressing R while hovering
in the Node Graph will produce a different result than pressing R while hovering the
mouse pointer in the Viewer.

Nodes are the building blocks of the process tree. Everything that happens to an
image in Nuke happens by using nodes.
Let’s explore the node’s graphical representation (FigUrE 1.9).
Input
FIGURE 1.9 A node’s anatomy.
Note Nuke is crossplatform,
meaning it
works on Windows,
Linux, and Mac oS X.
Windows and Linux
machines use the modifier
key called Control
(Ctrl), but on the Mac
this is called Command.
I will use the short form
for these, but will always
mention both options.
Ctrl/Cmd-S means press
Control or Command and
the S key simultaneously.
Node name
Mask input
output
A node is usually represented by a rectangular shape with the name of the node in
the middle. There’s usually an input (or more than one) at the top of the node, and a
single output at the bottom. on some nodes there is a mask input on the side of the
node, the functionality of which is discussed in more detail in Chapter 3.
creating a node
There are several ways to create nodes. Probably the best way is to choose a node
from the Nodes Toolbar. The Nodes Toolbar is split into several toolboxes, as shown
in TABLE 1.1.
