  A wide choice of cinematic lenses enables motion-picture creators to adapt
image visual-appearance to their creative vision. Such choice does not exist in
the realm of real-time computer graphics, where only one type of perspective
projection is widely used, a linear perspective. This paper presents an
extended perspective imaging model, which can represent distortion and FoV
parameters of entire variety of film and photographic lenses (e.g., wide-angle,
fisheye, anamorphic), while preserving parametrization in an artistically
convincing manner. Self-experimentation with the model revealed that each
projection type provides accurate perception of a different aspect of depicted
space (e.g., speed, distance, shape). Presented model, enables combination of
multiple projections, each on a different axis of the image, to achieve optimal
perception for a given scenario. This new projection, named aximorphic, was
made available here, under an open license (CC BY-SA 3.0), for a wide and easy
adoption.
