SIGNED DISTANCE OUTLINES
Signed Distance Fields are very versatile. In this installment of the Entagma tutorial stream, Manuel shows you how to use a SDF volume to create outlines around an arbitrary object. By remapping the values from the SDF using functions like sqrt() and sin() it’s easy to create propagating ripples.
Due to the fact that the SDF is defined in 3D space the setup can easily be animated, too, to create some fake water ripples.
