Camera Models and Optical Systems Used in Computer Graphics: Part I, Object-Based Techniques
نویسندگان
چکیده
Images rendered with traditional computer graphics techniques, such as scanline rendering and ray tracing, appear focused at all depths. However, there are advantages to having blur, such as adding realism to a scene or drawing attention to a particular place in a scene. In this paper we describe the optics underlying camera models that have been used in computer graphics, and present object space techniques for rendering with those models. In our companion paper [3], we survey image space techniques to simulate these models. These techniques vary in both speed and accuracy.

Camera Models and Optical Systems Used in Computer Graphics: Part II, Image-Based Techniques
In our companion paper [5], we described the optics underlying camera models that have been used in computer graphics, and presented object space techniques for rendering with those models. In this paper, we survey image space techniques to simulate these models, and address topics including linear filtering, ray distribution buffers, light fields, and simulation techniques for interactive appl...
متن کاملModeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism
In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...

متن کاملOnline multiple people tracking-by-detection in crowded scenes
Multiple people detection and tracking is a challenging task in real-world crowded scenes. In this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. We have detected objects with deformable part models and a visual background extractor. In the tracking phase we have used a combination of support vector machine (SVM) person-specific classifie...
متن کاملNapkin Sketch
This paper describes, Napkin Sketch, a novel 3D sketching interface which attempts to mimic the qualities of conventional sketching medium and tools both in terms of physical properties and interaction experience. A portable tablet PC is used as the sketching platform, and mixed reality techniques are employed to allow 3D sketches to be created on top of a physical napkin. Intuitive manipulatio...
