   Perspective Distort Fx Iwa

● Overview

This effect is for generating the movement of the ground at the time of Follow (Front Moves Fast, Back Moves Slow = Motion Parallax).

Since the deformed trapezoid is stretching the picture to the left & right, there is no vertical distortion.

In other words, the contraction in the vertical direction by the depth must be incorporated in the pre-input image.

Also, if you want to apply this effect to the background to parallel move, the movement of the background must be folded into the SubXsheet.

● Input Port

Source : Connect the input image.

● Parameters

Vanishing Point : The center point at the time of deformation. Used by perspective projection which is based around the vanishing point.

Anchor Point : The point that determines the criteria of the vertical position of the deformation. Pixels above this point will not be drawn (Becomes Transparent).

In addition, a picture with a horizontal line passing through this point, does not change in size.

Precision : Since the deformation is carried out only by expansion, the resolution will fall. In order to maximize the resolution of deterioration,

deform by calculating the input image in advance by a factor of this value with a finer resolution.

There is no sense to increase the Precision more than the value obtained by dividing the "Capture Resolution of Background" by the "Output Resolution".
