Solid Torus

Overview

Creates a donut-shaped torus. It is the basic primitive for any ring with an opening, including finger rings, swim rings, well rims, and planetary rings.

• Coordinate system: z-up (x right, y back, z up). Sizes are in units and are converted to pixels by pixels_per_unit during rendering.

Usage tips

• Understand the two radii: major_radius controls the overall ring size, measured from the center to the center of the tube; minor_radius controls tube thickness. Move minor closer to major for a thick donut.
• The torus is generated horizontally in the xy plane. Stand it up 90 degrees with solid_transform for a vertical ring such as a hoop or frame.
• Half a torus becomes a handle or arch. Intersect it with solid_box using solid_intersect to cut it into a semicircle.

• solid_transform — stand it up or tilt it
• solid_intersect / solid_subtract — cut away part of it
• solid_render — convert it to pixel art
• solid_sphere — combine it with a sphere, for example in a jeweled ring

Examples

Use it for rings, swim rings, and well rims.
