Virtual camera selection using a semiring constraint satisfaction approach
… worlds view renderings from the viewpoint of a virtual camera. As such, determining a good view of the scene is important to present a good game or three-dimensional world. Previous research has developed technologies to nd good positions for the virtual camera, but little work has been done to …

Probabilistic Roadmaps for Virtual Camera Pathing with Cinematographic Principles
… a system for the automatic generation of virtual camera paths for fly-throughs of a digital scene. The sample scene used in this work is an underwater setting featuring a shipwreck model with other virtual underwater elements such as rocks, bubbles and caustics. The digital shipwreck model …

Investigating the use of synthetic media and real-time virtual camera filters for supporting communication and creativity
Virtual representations of ourselves can influence the way we think, feel and behave. While this phenomenon has been explored heavily in the realm of Virtual Reality, little is known about the utility of synthetic media and real-time camera filters to reshape the perspective we have of ourselves …

Single Camera Motion Compensated Viewpoint Shift
… laptop and webcam configurations position the camera at the top of the screen, meaning that when the user looks at other people’s faces in the center of the screen, the camera captures the user looking downward, creating the impression of poor eye contact for remote participants. Solutions …

An Ecological Display for Robot Teleoperation
… by viewing range and video information from a virtual camera trailing the robot. This is rendered in 3-D by using standard hardware acceleration and 3-D graphics software. Our studies demonstrate that this interface improves performance for most people, including those that do not have much …

Perceptual Manipulations for Hiding Image Transformations in Virtual Reality
Users of a virtual reality make frequent gaze shifts and head movements to explore their surrounding environment. Saccades are rapid, ballistic, conjugate eye movements that reposition our gaze, and in doing so create large-field motion on our retina. Due to the high speed motion on the retina …

Design and analysis of a two-dimensional camera array
… the design and analysis of a two-dimensional camera array for virtual studio applications. It is possible to substitute conventional cameras and motion control devices with a real-time, light field camera array. I discuss a variety of camera architectures and describe a prototype system based …

Observational Animation: An Exploration of Improvisation, Interactivity and Spontaneity in Animated Filmmaking
… film. By utilizing real time capture for both virtual camera and actor performance, I hope to create a unique atmosphere in which both character and camera operator have the ability to influence action and actively participate in an evolving narrative.</p><p>Observational films are known for …

A projective approach to computer-aided drawing
… also has tools for intuitive navigation of a virtual camera, as well as methods for manipulating drawn primitives so that they appear to undergo three-dimensional translations and rotations. The new representation also supports automatic shading of primitives using either realistic or …

Multi-scale representations of virtual 3D city models
Virtual 3D city and landscape models are the main subject investigated in this thesis. They digitally represent urban space and have many applications in different domains, e.g., simulation, cadastral management, and city planning. Visualization is an elementary component of these applications. …

Exploring the World's Visual History
… technique to create 3D time-lapses, where the virtual camera moves continuously in time and space, creating compelling parallax effects. Next, I propose the 3D Wikipedia, a system that analyzes online text together with online photos to automatically create interactive visualizations of famous …

Surveying Underwater Shipwrecks with Probabilistic Roadmaps
… path that permits the AUV, equipped with a camera to "see" all sides of a region of interest (i.e. a shipwreck). This allows the region of interest to be completely documented. Photogrammetry can then be used to reconstruct a three-dimensional model, but a path is needed to do so. Paths are …

Intelligent Cinematic Camera Control for Real-Time Graphics Applications
… either gets to control their own freely-moving camera or they get to see the view that a specific player sees. This thesis presents a system for the generation of cinematically-pleasing views for spectating real-time graphics applications. A custom real-time engine has been built to demonstrate …
