Draws a line where an edge is detected. It features several solvers
Several method can be used, the result of which entirely depends on what is drawn on the screen.
Checks the difference between a pixel’s normal value and their distance from the camera.
Cross Depth Normals
Works the same as the method described above, but also draws an edge vertically for greater precision.
Generally creates edges on silhouettes. Draws an edge where neighboring pixels greatly differ in their depth value. Same method as used in “Borderlands”.
Uses the image’s luminosity (grayscale image) and creates an edge where the values differ. This works great for aesthetics that make use of strong and sharp color difference.
