Warps an image from equirectangular (spherical) format to circular fisheye format.
Equirectangular Image— The image to warp. Its aspect ratio should be 2:1.
Field of View— The output image’s angle of view, in degrees.
Roll— The amount, in degrees, to rotate the image along the X, Y, and Z axis respectively. The rotations are performed in that same order: tilt, then pan, and finally roll.
Opaque Edges— Whether to make the areas outside the circular fisheye image solid black (if true) or transparent (if false).
Edge Width— The size of the circle, in Vuo Coordinates.
Edge Sharpness— How sharp the edge of the circle is. A value of 0 means the edge is very soft; a value of 1 means the edge is sharp.
Width— The size of the output image, in pixels. The output image is a square — equal width and height. When set to
Auto, the smaller dimension (height) of the input image is used.
Fisheye Image— The resulting circular fisheye image.
