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… WebDemo for Volume Raycasting using ModernGL. A simple Volume Raycasting demo using PyQT5 and ModernGL. The demo requires OpenGL >=4.1 and has been tested on OSX …
