Radial Ramp Tool
The Radial Ramp tool lets you create images with a variety of properties and
in several formats. The Radial Ramp tool has three sets of color channel value
fields that allow you to generate a multi-color image based on RGBA values.
One set of values is for generating the fill color, and two sets are for generating
start and end radially ramped colors arranged around a central axis region of
definition (ROD). The fill color is defined as those pixels residing outside the
ROD. Other controls let you to position the X and Y axes of the central ramp
at any location, stretch the ramp vertically or horizontally, and define the
falloff center point and range.
NOTE The following procedure assumes that you have a Schematic and a Player
view open.
To create a radially ramped image using the Radial Ramp tool:
1 Drag the Radial Ramp tool from the Tools tab to the dependency graph
in the Schematic view and attach it to the Output node.
