     * Pinhole camera. A pinhole camera is a linear mapping between 3D and 2D
     * worlds. Pinhole cameras only take into account translation, rotation and
     * camera intrinsic parameters such as focal length, aspect ratio, skewness
     * and principal point.
     * Pinhole cameras perform projective mappings between 3D and 2D worlds,
     * in other words, the farther an object is, the smaller is represented or
     * parallel lines converge into vanishing points.
     * Pinhole cameras cannot be used for orthographic projections (where
     * parallelism between lines is preserved and there are no vanishing points).
