Box 2D SDFCopy Anchor Link

Creates a flat rectangle in the XY plane. The node ignores the Z axis, so the shape extends as an infinite slab through depth.

---

Pyramid SDFCopy Anchor Link

Creates a pyramid standing upright along the Y axis. The square base lies flat in the XZ plane, squared to the X and Z axes, and the tip points up. Its body is centered on the origin, so the base sits half the height below it and the tip half the height above.

Roundness rounds the rims inwards, so each flat end is roundness narrower than the radius given for it.

Inputs: Position, height (the full extent along Y), base radius and top radius (the radii of the cone at its two ends, measured before the rims are rounded), and roundness (how far the fillet reaches, capped at half the height).

Star 2D SDFCopy Anchor Link

Creates a flat star in the XY plane, with one point facing right along the X axis. The node ignores the Z axis, so the shape extends as an infinite prism through depth. Inner Ratio sets how deep the notches cut. Near 1, the star rounds out into a polygon, and near 0, it becomes a spiky asterisk.

Inputs: Position (usually from Pixel Position, of which the node reads only X and Y), radius (distance from the center to each outer point), inner ratio (0-1), and the number of points.
