Edge Detection

Edge Detect image effect adds black edges to the image wherever color differences exceed some threshold.

If more sophisticated geometry-based edge detection is required, the Standard Assets also provide such a normals and depth-based edge detection effect.

As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.
