Demo Tutorial

Rotating Cube

moon run src/demo --target native

The default demo renders a rotating cube with dotted background, Z-buffering, backface culling, flat lighting, and terminal y-scale correction.

Static Sphere

moon run src/demo --target native -- --sphere

The sphere demo uses a higher-subdivision UV sphere and remains static so the faceted lighting is easy to inspect.

Rotating Torus

just torus

The torus uses outward face winding so backface culling shows the exterior rather than the inner wall. just also forwards the detected terminal dimensions.

Hitchcock Zoom Scene

moon run src/demo --target native -- --hitchcock

This scene keeps a central cube visually stable while the camera distance and projection scale change together. A cylinder, cone, triangular pyramid, and rotated variants sit behind the cube, making the dolly zoom effect visible.

Smoke Tests

moon run src/demo --target native -- --once
moon run src/demo --target native -- --sphere --once
moon run src/demo --target native -- --hitchcock --once

Use --once when validating the renderer in scripts or CI-like local checks.

Use just record, just export-image, and just show-image for the default sequence and static-image workflows under the ignored target/ directory.
