Light can be analyzed as: rays, waves, or photons. Light is bent by a lens to produce an image. Light from an object is flipped by a lens. Used because it matches the way we see. Figure out where the ray from the object to the eye intersects the picture plane. Monocular depth clue given by objects obscuring others. Object faces are parallel to the image plane. Advantage: object can be measured with a scale. Projectors are still perpendicular to image plane, but faces are not parallel. Like a cube drawn on a 3d plane in math. One point perspective: lines perpendicular to the picture plane converge to the vanishing point. Two point perspective: lines converge to 2 vanishing points. Location, view direction, and frustum must be defined relative to the object. Model coordinate system is the right-handed 3d coordinate system.
