Coordinate System

equilib uses a right-handed XYZ global coordinate system. The x-axis faces forward and the z-axis faces up.

• roll: counter-clockwise rotation about the x-axis
• pitch: counter-clockwise rotation about the y-axis
• yaw: counter-clockwise rotation about the z-axis

You can flip the coordinate system so that the z-axis faces down by passing z_down=True to any transform.

Equirectangular image

An equirectangular image is any image with a 2:1 aspect ratio that captures a 360° field of view. Common sizes:

• 2160s: 3840x1920
• 2880s: 5760x2880
