User Manual

Light Angle
This sets the angle of the simulated light source.
Spread
This widens the Displacement effect and takes the edge off the Refraction map. Higher values
cause the ridges or edges to spread out.
Light Channel
Select the channel from the refraction image to use as the simulated light source. Select from
Color, Red, Green, Blue, Alpha, or Luminance channels.
NOTE: The Radial mode pushes pixels inward or outward from a center point, based
on pixel values from the Displacement map. The XY mode uses two different channels
from the map to displace pixels horizontally and vertically, allowing more precise
results. Using the XY mode, the Displace node can even accomplish simple morphing
effects. The Light controls allow directional highlighting of refracted pixels for
simulating a beveled look.
Common Controls
Settings Tab
The Settings tab in the Inspector is also duplicated in other Warp nodes. These common
controls are described in detail at the end of this chapter in “The Common Controls” section.
Drip [DRP]
The Drip node
Drip Node Introduction
The Drip node creates a ripple effect over the entire image, which has the potential to animate
outward from a central source. There are a variety of different Drip effects from which
to choose.
Inputs
The two inputs on the Drip node are used to connect a 2D image and an effect mask, which
can be used to limit the warped area.
–
Input: The orange input is used for the primary 2D image that is warped.
–
Effect Mask: The blue input is for a mask shape created by polylines, basic primitive
shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input
limits the warping to only those pixels within the mask. An effects mask is applied to
the tool after the tool is processed.
