Vortex [VTX]
The Vortex node
Vortex Node Introduction
The Vortex effect appears as a swirling whirlpool in specified regions of the image. The Vortex
can be made to move and grow by animating the various controls.
Inputs
There are two inputs on the Vortex node for the primary 2D image and the effect mask.
–
Input: The orange image input is a required connection for the primary image you
wish to swirl.
–
Effect Mask: The optional blue effect mask input expects a mask shape created
by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools.
Connecting a mask to this input limits the swirling vortex to only those pixels within
the mask. An effects mask is applied to the tool after it is processed.
Basic Node Setup
Below, the Vortex is applied to text for creating motion graphics. Since the Vortex will cause the
text to swirl outside the text boundary, a Set Domain node is used to expand the text boundary,
ensuring that the text is not cropped when the Vortex is applied.
