fn orbit_camera(size: (u32, u32), azimuth: f32, elevation: f32) -> CameraExpand description
A camera orbiting ORBIT_TARGET at azimuth and elevation, in radians.
The projection comes from super::camera_looking_at, so it follows the
frame’s own aspect: the built-in pipeline compares depth with Greater and
clears to the far plane, so the projection is reverse-z infinite.
