Raytracing
Metal Fuzziness Property Variation.
Here we see the effects of varying the material roughness in metal surfaces. On the left we have a lower fuziness with a more polished look and on the right we have a higher fuziness, more rough and blurry metal.
It looks good, let's see it animated.
Refractive Index Variation.
Here we see the effects of varying the refractive index in glassy materials. On the left the index is closer to 1.0, the air index, on the right it approximates 2.42, which is diamond.
Now animated.
Point Lights.
Raytracing render using point light sources.
We will leave you with a little extra, a focus blur animation.
