WebSep 4, 2024 · How The Turing GPU Does Ray-tracing (Explanation For Humans) Modern GPU’s are incredible. Prior to the RTX series, video cards had to fake lighting because real lighting was required too much math. WebYou can see this by fixing the x-value, such that ax = c1, to get the equation z = c1 + by + c. Then you can combine the two constants, c and c1 into a new constant c2, to get z = by + c2. This is the equation for a line. So for every x-value you pick, you get a line and an infinite number of lines side-by-side gives you a plane.

One can think of this "ray" as a stream of photons traveling along the same path. In a perfect vacuum this ray will be a straight line (ignoring relativistic effects). Any combination of four things might happen with this light ray: absorption, reflection, refraction and fluorescence. A surface may absorb part of the light ray, resulting in a loss of intensity of the reflected and/or ref… sig figs in combined operations
