WebJan 16, 2016 · A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired by a CT, MRI, or MicroCT scanner. Usually these are acquired in a regular pattern (e.g., one slice for each millimeter of depth) and usually have a regular number of image pixels in a regular pattern. This is an example of a regula… WebRaycasting Raycasting is historically the first volume rendering technique. It has common with raytracing: • image-space method: main loop is over pixels of output image •a view rayper pixel (or per subpixel) is traced backward • samples are taken along the ray and composited to a single color Ronald Peikert SciVis 2007 - Raycasting 3-4 how is environmental variation caused
