Displacement Mapped Billboard Clouds
This paper introduces displacement mapped billboard clouds (DMBBC), a new image-based rendering primitive for the fast display of geometrically complex objects at medium to far distances. The representation is based on the well-known billboard cloud (BBC) technique, which represents an object as several textured rectangles in order to dramatically reduce its geometric complexity. Our new method...
متن کاملMultimedia Science Presentations and Teaching Aids
Over the past several years the author, a paleoecologist in the Terrain Sciences Division of the Geological Survey of Canada, has participated in the creation of several multimedia CD productions. All are designed to present large science projects in a manner that is suitable for the layperson as well as useful to the specialist. To achieve this goal, they employ several software applications n...
متن کاملTree Rendering with Billboard Clouds
This paper presents a method to render complex trees on high frame rates while providing accurate occlusion and parallax effects. Based on the recognition that a planar billboard is accurate if the represented polygon is in its plane, we find a billboard for each of those groups of tree leaves that lie approximately in the same plane. The tree is thus represented by a set of billboards, called ...
متن کامل3D Video Billboard Clouds
3D video billboard clouds reconstruct and represent a dynamic three-dimensional scene using displacementmapped billboards. They consist of geometric proxy planes augmented with detailed displacement maps and combine the generality of geometry-based 3D video with the regularization properties of image-based 3D video. 3D video billboards are an image-based representation placed in the disparity s...
متن کاملSkybox as Info Billboard
In this paper we propose a new way of information mapping to the upper part of the virtual skybox. This mapping brings improvement to the existing virtual world’s projects with providing relevant information instead of a static or animated skybox. Information that is used in our approach is visualized in a chronological correspondence. We explain basic terms as well as previous similar projects...
