Raycasting: Direct Volume Rendering PDF Voxel - Scribd
WebFeb 1, 1982 · This paper presents ray casting as the methodological basis for a CAD/CAM solid modeling system. Solid objects are modeled by combining primitive solids, such as blocks and cylinders, using the set operators union, intersection, and difference. To visualize and analyze the composite solids modeled, virtual light rays are cast as probes. In its basic form, the volume ray casting algorithm comprises four steps: 1. Ray casting. For each pixel of the final image, a ray of sight is shot ("cast") through the volume. At this stage it is useful to consider the volume being touched and enclosed within a bounding primitive, a simple geometric object — usually a cuboid — that is used to intersect the ray of sight and the volume. Webray casting, introduced in 1982 by Scott Roth [9]. All of these methods rely on more or less direct evaluation of the rendering integral. Some of them strive for visual quality of the rendered image (ray casting), while others aim for speed and performance (marching cubes, texture-based approaches).
