- LensDistortion: undistort and STMap (
examples/transform/lens_distortion.oink): LensDistortion with a barrel k1 undistorts the Golden Gate photo. A second LensDistortion writes the same warp as an STMap (uv in red/green), and the STMap node applies it: that is how distortion is handed between packages.
