Shapes and Segments
Shape-Z defines high-level 2D shapes that can be extruded and subdivided with segments. These are the foundational building blocks for modeling walls, floors, and curved surfaces.
Inside shapes we have two helper variables:
sdf– the raw signed distance (negative inside, positive outside).inside– convenience alias for-sdf(positive inside, zero on the surface).
Rect
A rectangular shape that spans the full domain in its plane. It supports subsegments like Floor, Ceiling, Left, Right, Back, and Front, which allow fine-grained control over geometry placement.
- Coordinate system: Cartesian
- Axes:
u,v,d(e.g., for a Floor segment,u = x,v = z,d = y) - Typical usage: Rooms, flat walls, layered architecture
Example
Disc
A circular shape with a radial layout. It does not support subsegments, but instead provides u, v, and d in polar coordinates, ideal for modeling towers, fans, and radial symmetry.
- Coordinate system: Polar
u: angle (normalized 0–1)v: radius (normalized)d: height- Typical usage: Cylindrical bases, circular panels, decorative columns
