Corner Positioner [CPN]
The Corner Positioner node
Corner Positioner Node Introduction
The Corner Positioner can be used to position the four corners of an image interactively. This
would typically be used to replace a sign or other rectangular portion of a scene. Connect all
corners to Paths or Trackers for animation purposes.
Inputs
The two inputs on the Corner Positioner 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 Corner Positioner to only those pixels within the mask. An effects mask is
applied to the tool after the tool is processed.
Basic Node Setup
Below, the Corner Positioner is used to position the rectangular corners of the MediaIn2 to fit
within a specific area of the MediaIn1 node. A Planar Tracker tracks the background, and then a
Planar Transform is used to keep the Corner Positioner in place as the background clip moves.
Once the planar tracking is completed, and the Planar Transform is created, the Planar Tracker
node is no longer needed, and you can delete it.
The Corner Positioner corner pins a clip in place and uses
a Planar Transform to match move it to the background
