The sdAnnularShape node generates a signed distance image of an annular shape based on its input, by substracting a constant from the absolute value of the distance function (i.e. creating a ring around the shape).
The sdAnnularShape node accepts an input in signed distance function format.
The sdAnnularShape node generates a signed distance function of the annular version of the input shape.
The sdAnnularShape node accepts the following parameters:
the distance to be substracted from the absolute value of the function (i.e. half the width of the ring)
