![]() We need to follow physics as much as possible. Since I can't model worth crap, I downloaded a diamond cut according to the classic "round brilliant" from here, and made this supercomplex scene:įirst, make sure you have your gamma correction enabled, diamonds, like all physical things, should be rendered linearily. We start with a ridicolously simple 3D model. It is also coupled with the fact that the " cut " of a diamond is specifically made to enhance the "fire" (dispersion) and "brilliance" (ability to reflect light back to the viewer) as much as possible.īut even before we get to the actual dispersion part of things, lets try to see what it takes to render realistic gem's without it first. These stem from the fact that Diamond is a material with very high dispersion. One of the reasons is the characteristic property of fine diamonds known in the gem business as "fire" - the nice "pretty colors".
