RayTracer class

Performs multi-bounce ray tracing against RaycastColliderComponent entities that have RaycastColliderComponent.isReflective set to true.

Each bounce reflects the ray's direction around the surface normal and multiplies the remaining distance budget by RaycastColliderComponent.reflectivity.

Example:

final tracer = RayTracer(raycastSystem: raycastSys, maxBounces: 3);
final trace = tracer.trace(Ray(origin: origin, direction: dir));
for (final seg in trace.segments) {
  drawBeam(seg.from, seg.to, hitPoint: seg.hit?.point);
}

Constructors

RayTracer({required RaycastSystem raycastSystem, int maxBounces = 3, double minReflectivity = 0.1})
