Operation Soft Shape#

Inputs#

float Sdf

float Softness | default 0.1

Behaviour#

Turns the signed distance field into a mask with softly feathered edges. Outside of the sdf will be fully black inside will be white and the border transition softly between.

Properties#

ESoftShapeFunction SoftShapeFunction | default Smoothstep

With the SoftShapeFunction property one may choose which function to use in order to generate the soft shape.

• Linear: the cheapest option, provides a linear gradient over the edge
• Smoothstep: good results over all, provides a smooth gradient over the edge.
• ExpStep: a faster, yet smooth falloff than Smoothstep
• LogStep: an extremely fast falloff

The following figures are at Softness of 0.01.
