Ray-Traced Reflections is a ray tracing feature in the High Definition Render Pipeline (HDRP). It is an alternative, more accurate, ray-traced solution to Screen Space Reflection that can make use of off screen data. Screen-space reflections Ray-traced reflections

Unity real-time ray tracing for high fidelity reflections

Ray Traced Reflections is a replacement for screen space reflection that uses a ray traced reflection technique that can use off-screen data. Ray Traced Shadows replace shadow maps for Directional, Point, and Area Lights. Recursive Rendering replaces …

Adding Reflection and Refraction Writing a Basic Ray Tracer Source Code The other advantage of ray-tracing is that, by extending the idea of ray propagation, we can very easily simulate effects like reflection and refraction, both of which are handy in …

First we compute the reflection direction. For that we need two items: the normal at the point of intersection and the primary ray’s direction. Once we obtain the reflection direction, we shoot a new ray in that direction. Going back to our old example, let’s say the reflection ray hits the red sphere.

We'll call these flows “light rays.” wLight rays travel in straight lines in free space. wLight rays do not interfere with each other as they cross. wLight rays obey the laws of reflection and refraction. wLight rays travel from the light sources to the eye, but the physics is invariant under path reversal (reciprocity). 4 Eye vs. light ray tracing

graphics - glossy reflection in ray tracing - Stack Overflow

In comparison, the image below is from the mirror reflection This is my code about glossy reflection, basically, once a primary ray intersect with an object. From this intersection, it will randomly shot another 80 rays, and take the average of this 80 rays color.
