FourCorner

Transformv1coreConcat: Xform

Overview

Maps the image onto four corners — screens, signs, posters. Track the corners, pin the insert.

How to

How-to

Drag the four to corners in the viewer (or bake them from a QuadTracker); the from corners are the source rectangle.
filter picks the resample; use it for screens, signs and posters.

Parameters

Parameter	Type	Default	What it does
to1	Float2	[0.0, 0.0]	The corner's destination, in pixels. Drag it in the viewer.
to2	Float2	[1920.0, 0.0]	The corner's destination, in pixels. Drag it in the viewer.
to3	Float2	[1920.0, 1080.0]	The corner's destination, in pixels. Drag it in the viewer.
to4	Float2	[0.0, 1080.0]	The corner's destination, in pixels. Drag it in the viewer.
from1	Float2	[0.0, 0.0]	The corner's source position, in pixels. Usually the input's own corners.
from2	Float2	[1920.0, 0.0]	The corner's source position, in pixels. Usually the input's own corners.
from3	Float2	[1920.0, 1080.0]	The corner's source position, in pixels. Usually the input's own corners.
from4	Float2	[0.0, 1080.0]	The corner's source position, in pixels. Usually the input's own corners.
filter	Choice	bilinear	The resampling filter. Cubic for general work; impulse to keep hard pixels. `impulsebilinearcubicmitchelllanczos`
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
