Enum BillboardMode 

pub enum BillboardMode {
    None,
    Cylindrical,
    Spherical,
}

How a billboard instance turns to face the camera (BB.2). Set per instance via SceneRenderer::add_billboard_instance / set_billboard_mode; applied each face_billboards_to.

Variants

None

Not auto-oriented — the host drives its transform directly. Default (so a billboard record with no mode is inert).

Cylindrical

Yaw-only: the slab stays vertical (image up = world up) and rotates about the vertical axis to face the camera. The Doom/Build default — its cast shadow stays sane (a vertical card) as the camera orbits.

Spherical

Full face: the slab is always perpendicular to the camera direction (pitches with the view). Ideal head-on, but its cast shadow rotates as you orbit.
