Linux

Creates a texture containing a DisplacementMap in the Red and the Green channel for undistorting a camera image. This call can take quite some time to process depending on the resolution.

Inputs

	In Exec
	Lens Parameters Open CVLens Distortion Parameters Structure (by ref)	The Lens distortion parameters with which to compute the UV displacement map.
	Image Size Int Point Structure (by ref)	The size of the camera image to be undistorted in pixels. Scaled down resolution will have an impact.
	Cropping Factor Float	One means OpenCV will attempt to crop out all empty pixels resulting from the process (essentially zooming the image). Zero will keep all pixels.

Outputs

	Out Exec
	Camera View Info Open CVCamera View Info Structure	Information computed by OpenCV about the undistorted space. Can be used with SceneCapture to adjust FOV.
	Return Value Texture 2D Object Reference	Texture2D containing the distort to undistort space displacement map.
