This emitter is positioned somewhere “above” the origin – to the right in the image above. Each point defines a Tracer aimed along the negative Z-axis. The sdf in this example is a single sphere at the origin.

WebNov 9, 2024 · The best way to start to explore ray tracing is to start by observing nature. In nature, rays of light are emitted from a light source. That light bounces off a surface. That bounce can be specular where it changes direction — either through a reflection or refraction — or it can be diffuse where it scatters in all directions.
