Abstract

In film conversation shots, there are constraints that specify the players' positions as they are projected on the screen. How to project the two players on the appropriate position on the screen is the main problem focused on this thesis. Some important rules of film grammar for two players are stated in this paper and an algorithm based on camera control to achieve desired projected position on screen for players are provided. The results of the algorithm for lots of shots in two players conversation satisfy all the constraints related with camera placement for two players in film grammar. Translating film grammar into mathematic requirement for 3D graphics and building the corresponding equations are showed in this paper. And a creative and effective way to solve these equations is stated. This algorithm provides a feasible way to control the camera in graphics environment. And several cinematographic shots are implemented by this algorithm, and also a sequence of shots is applied into a film scene.
