Shide Xiao, Wen Meng, Hong Dong, A space partition based on octree ray tracing algorithm technology. Computer Applications III 2008, 3. Google Scholar. Qing Lan, GPU-based ray tracing algorithm and implementation. Computer Science and ... WebThe main idea is: each stair is a sequence of lines with similar domain of definition, and the staircase is a sequence of such elements. To avoid unnecessary computations, an octree is used to down-sample the environment point-cloud data. The resulting centroids are stored in n arrays, each containing points with equal height.
Interactive Isosurface Ray Tracing of Large Octree Volumes
WebDespite the fact that realistic images can be generated by ray-tracing and radiosity shading, these techniques are impractical for scenes of high complexity because of the extremely high time cost. Several attempts have been made to reduce image synthesis time by using parallel architectures, but they still suffer from communication problems. In this paper, we … WebJan 1, 1996 · We propose the Octree-R, an octree-variant data structure for efficient ray tracing. The algorithm for constructing the Octree-R first estimates the number of ray … songs used for different motives
How can I create an octree from a point cloud without raytracing?
WebRay-tracing methods determines all rays between the receiver and the transmitter by applying the image based technique. ... device configuration and will reflect and refract in the environment model that is defined by a Quadtree or an Octree.
