| - | I propose abandoning the constraints of the conventional planar pinhole camera model by no longer requiring that rays be straight, converge, or sample space uniformly. Camera models can then be designed for specific applications and optimized dynamically for each 3-D scene or dataset to achieve adequate sampling. Another consideration in camera model design is preserving image computation efficiency in order to support interactive rendering of dynamic scenes. | + | In order to create images that better sample 3-D scenes, I propose abandoning the constraints of the conventional planar pinhole camera model by no longer requiring that rays be straight, converge, or sample space uniformly. Camera models can then be designed for specific applications and optimized dynamically for each 3-D scene or dataset so as to achieve adequate sampling. At the same time, camera models should also be designed to preserve image computation efficiency in order to support interactive rendering of dynamic scenes. |
