Interaction, navigation, and visualization props in complex virtual environments using image based rendering techniques

摘要

Present an image-based technique for accelerated rendering of world-in-miniature (WIM)-based and multiple-viewpoint-based props. The WIM technique offers an intuitive and useful tool for navigation and manipulation within virtual environments. The multiple-viewpoint technique is often applied for enhancing visualization and navigation. Unfortunately, both approaches require multiple rendering of the viewed data. This can significantly deteriorate the frame rate and negatively influence the interaction. The proposed approach circumvents this drawback, while still providing the features of these tools.
