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.

    simply make a "reference copy" of the transform node instead of reference each transform, rotate;o)

    And if you really need to reference the three components of a parameter, click on its name to copy/paste all components at once :)

    Is there an easy and elegant way of converting those ripples to curves?
