Photogrammetry is about geometric modeling of real world from images. By the same token, computer graphics is about geometric modeling for scene rendering. Both photogrammetry & computer graphics share the core fundamentals of geometrical modeling and they can leverage each other. Indeed, computer vision fills this need for computer graphics in terms of supplying the geometric world. On the other hand, the mind set and the tools of photogrammetry could serve a critical needs for this world in terms of accuracy and visual fidelity. In fact, the crunching machine of 3D photogrammetric mapping can be deployed to a shear amount of application in computer graphics. I'm asking this kind of questions to stimulate more ideas on how we can push photogrammetry into a new horizon of applications.
