Lidinoid Field

About this Block

What it does: Creates an unbounded Scalar Field defined by a Lidinoid Triply Periodic Minimal Surface (TPMS). The following equation defines the field:

sin(2*x) * cos(y) * sin(z) + sin(2*y) * cos(z) * sin(x) + sin(2*z) * cos(x) * sin(y) - cos(2*x) * cos(2*y) - cos(2*y) * cos(2*z) - cos(2*z) * cos(2*x) + .3 = 0

The Cell size input specifies the size of the period for a single repetition in x, y, and z. The amplitude of the distance field scales from -1 to 1 through one period of the pattern. Common uses: Scalar Field input for a Ramp block. Tips:

View the field by using the Field Viewer (hot-key f).
The values in the Lidinoid Field are unitless and do not represent an implicit body. Alternatively, the Lidinoid Body block creates a similar field with distance units and an approximate distance field.
