Detailed Description

Cast rays to determine if and where they intersect geometry.

The basics of raytracing entail casting a ray from an origin point in a specific direction and determining whether or not it intersects with a set of geometry. Certain functions can even determine where the intersection occured. Generally, every RayTracer will contain a set of geometry and provide functions for casting rays from an origin point in a specific direciton. Some generate an accelerated structure from geometry called a Bounding Volume Hierarchy, or BVH. A BVH can drastically decrease the time it takes to calculate ray intersections, but can be more complicated to manage compared to standard buffers of geometry.
