● Overview
manongjohn
5d1508
This effect is for generating the movement of the ground at the time of Follow (Front Moves Fast, Back Moves Slow = Motion Parallax).
manongjohn
5d1508
Since the deformed trapezoid is stretching the picture to the left & right, there is no vertical distortion.
manongjohn
5d1508
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.

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

5d1508
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).

5d1508
In addition, a picture with a horizontal line passing through this point, does not change in size.
manongjohn
5d1508
Precision : Since the deformation is carried out only by expansion, the resolution will fall. In order to maximize the resolution of deterioration,
manongjohn
5d1508
deform by calculating the input image in advance by a factor of this value with a finer resolution.
manongjohn
5d1508
There is no sense to increase the Precision more than the value obtained by dividing the "Capture Resolution of Background" by the "Output Resolution".
