User Manual

Show Key Points, Handles, Grid, and Subdivisions
Use these four options to enable or disable the display of the grid, key points (vertices), Bézier
handles, and subdivisions in the viewers.
Reset Selected Points
This resets Selected Points (vertices) to their default positions.
Reset All Points
This resets all points (vertices) in the mesh to their default positions.
Stop Rendering
This option stops rendering, which disables all rendering of the Grid Warp node until the mode
is turned off. This is frequently useful when making a series of fine adjustments to a
complex grid.
Grid Warp Toolbar
Whenever the Grid Warp node is selected and is in Edit Grid mode, the Grid Warp toolbar is
displayed in the views. This toolbar provides a variety of options for manipulating and adjusting
the grid. The toolbar buttons in this toolbar are described in the preceding “Contextual Menu
Options” section.

controls are described in detail at the end of this chapter in “The Common Controls” section.
Lens Distort [LENS]
The Lens Distort node
Lens Distort Node Introduction
This node can be used to remove or add lens distortion in an image. The lens distortion in an
image depends on the lens, quality, number of elements, and many other factors.
One reason to remove lens distortion is to composite with an undistorted layer. For example,
compositing a 3D element over a distorted live-action layer will cause unwanted effects like
straight lines not matching up on the foreground and background. The resulting composite will
not look believable.
