Image sampling explained
- [Instructor] When working with a raytrace render engine such as V-Ray, I think a basic understanding of the technology can certainly benefit the image creation work that we do. In order to collect all of the information that we need so as to create a final render from a 3D environment, such as the shape of geometric objects, the surface and volume properties of any materials that may have been applied, lighting and shadow information etc, our render engine needs to somehow probe the 3D scene in order to determine just what ought to be drawn in each of the pixels of the squares that will ultimately make up the final image. The million dollar question of course is how will this gathering of information or scene probing be accomplished? Well, this is where understanding at least a little bit regarding the basic workings of the raytrace process can come in handy. In general terms then, raytracing works like this. From the rendering camera in the scene, the render engine will shoot a…
