Resumo:
With the evolution in graphics processing power and the popularizationof electronic games, new forms of entertainment, such as being a gamespectator. The requirements for positioning the camera for the spectatorsto view the games are different from those applied to players. The camerafor the players must fulfill playability requirements, while the camera forthe spectators must explore different viewing angles in order to increasethe immersion in the game environment and to explore the thrill of thescenes. The cinema has evolved a whole cinematographic language thatoptimizes the scene interpretation. Recent research has been seeking toapply cinematography to game visualization. The main challenge in theadaptation of the cinematographic language for games lies in the existence ofa dynamic environment in which the storys progress cannot be anticipated.Three modules can be identified to adopt the cinematographic language ingames: screenwriter, responsible for identifying what is happening in thescene; director/editor, responsible for defining the best takes to capture thescene; and cinematographer, responsible for positioning the camera in thedynamic environment to better comply with the director editors demands.The present work proposes the implementation of a cinematographer module.Based on camera position requirements obtained from an external module,we propose a camera model that automatically positions the camera.The positioning requirements are expressed by a set of constraints that mustbe respected by the camera model. The camera uses a physical model basedon a particle system oriented by Verlets method, and employs the relaxationmethod to obtain the systems convergence in order to comply with imposedconstraints. Computational experiments have demonstrated the capacity ofthe proposed module to comply with sophisticated camera positioning rulesbased on compositions of simple constraints. Cinematography principlessuch as framing, camera position and movement, and respecting the line ofaction are easily accomplished by the proposed module.
