Overview of volumetric rendering
Volumetric rendering is a collection of techniques used to generate a 2D view of discrete 3D data. This 3D discrete data could be a collection of images, voxel representation, or any other discrete representation of data. The main goal of volumetric rendering is to render a 2D projection of 3D data since that is what our eyes can perceive on a flat screen. This method generated such projections without any explicit conversion to a geometric representation (such as meshes). Volumetric rendering is typically used when generating surfaces is difficult or can lead to errors. It can also be used when the content (and not just the geometry and surface) of the volume is important. It is typically used for data visualization. For example, in brain scans, a visualization of the content of the interior of the brain is typically very important.
In this section, we will explore the volumetric rendering of a volume. We will get a high-level overview of volumetric...
