Ray-tracing: the newest development in practical graphics

As with most PC hardware, GPU technology continues

As with most PC {hardware}, GPU expertise continues to evolve at a breakneck tempo. A latest instance of evolving graphics expertise is “real-time ray tracing.” Ray tracing expertise permits for extra practical lighting results that extra precisely simulate the way in which gentle and reflections behave in the actual world.

As Nvidia describes it:

Ray tracing calculates the colour of pixels by tracing the trail that gentle would take if it had been to journey from the attention of the viewer via the digital 3D scene. Because it traverses the scene, the sunshine might mirror from one object to a different (inflicting reflections), be blocked by objects (inflicting shadows), or move via clear or semi-transparent objects (inflicting refractions). All of those interactions are mixed to provide the ultimate shade of a pixel that’s then displayed on the display.”
