Camera control in computer graphics

摘要: This course summarizes the motivations and requirements for camera control, presents an overview of state art, examines promising avenues hot topics future research. It classifies various techniques identifies representational limits commitments each. Approaches range from completely interactive based on possible mappings between a user's input parameters to automated paradigms in which moves jumps according high-level, scenario-oriented goals. Between these extremes lie approaches with more limited expressiveness that use algebraic constraint-based optimization techniques. The includes number live examples both commercial systems research prototypes, it emphasizes tough issues facing application developers, such as real-time handling visibility complex multiple targets dynamic environments (multi-object tracking).
