This Matchbox shader reframes a shot with respect to perspective distortion.
The concept of this shader is to simulate a different focal length alongside a different camera orientation (while maintaining the camera position).
Optionally the resulting image can be rotated via the
The source image must be free of lens distortion for the process to function properly. Therefore this shader features a basic image rectification.
Additionally this shader provides the option of outputting (continuous) UV coordinates.
Adaptive Degradation is supported by this shader and will bypass antialiasing if enabled.
While this shader works quite well when downscaling (using antialiasing), its unsuited for upressing.
Note that this shader uses
Warning: The matte (where present) is assumed to be of the same format as the source image. Otherwise the shader will produce incorrect results.
