Constructor Details

#initialize(camera_type: nil, location: nil, right: [-1.33, 0.0, 0.0], up: nil, direction: nil, sky: [0.0, 0.0, 1.0], angle: nil, look_at: nil) ⇒ Camera

camera_type: perspectice, orthographic, etc. Note: default values of some setting is modified from original povray

because of left-handed coordinate system.
This library provide only on right-handed system in crystallography.
