   Perspective Distort Fx Iwa

● Overview

Allows to generate a motion parallax movement effect on the Source image, where things in

front move faster than things in the back.

The image width is stretched to the sides, to transform it into a trapezoid, but it will not

be stretched vertically.

In other words, the contraction in the vertical direction caused by depth, should be

incorporated beforehand in the image.

Also, if you want to apply this effect to a moving background, the movement of the background

must be collapsed into a SubXsheet.

● Input Port

Source : Connect the input image.

● Parameters

Vanishing Point : The center point for the deformation. In the case of perspective

projection, this is the vanishing point.

Anchor Point : Defines the vertical position that will be the basis for the deformation.

Pixels above this point will not be drawn (become transparent).

It also defines the horizon line for the deformed image, maintaining the original image width.

Precision : Since the deformation is carried out only by expansion, the resolution will

suffer. In order to minimize resolution deterioration, the original image resolution is

multiplied by this value before being deformed.

There is no point in making Precision higher than the value obtained by dividing the

"Capture resolution of the background" by the "Output resolution".
