    Ray-traced shadows are shadows that HDRP generates by tracing rays of light from the following Light sources: Directional Point Spot Rectangle When you enable ray-traced shadows in your HDRP Project, they replace shadow maps …

c++ - Raytracing Shadows - Stack Overflow

    Basically, when an intersection is found, you set the shadowed flag to true, BUT you continue the cycle: this is both inefficient and incorrect. When an …

Shadow rays in Raytracing - Computer Graphics Stack Exchange

    https://computergraphics.stackexchange.com/questions/1734/shadow-rays-in-raytracing
    Try removing all the shading computation and just set the colour to intersections / 999999, so your unshadowed intersections are just white. Draw an object at the light position to make sure it's correct: in both your renders, it looks like it might be in the bottom-right of the image, between the two objects.

Fixing Ray-traced Shadow Content Issues with NVIDIA …

    In raster shadows, potentially shadow-casting objects are single-sided by default, whereas ray tracing treats them as physical objects and records both front and back face hits. This can easily be disabled by setting CVar r.RayTracing.Shadows.EnabledTwoSidedGeometry to 0. Figure 3. The Realistic Rendering sample with single-sided geometry shadows.

raytracing - Ray Tracing Shadows: The Shadow Line Artifact

    https://computergraphics.stackexchange.com/questions/4986/ray-tracing-shadows-the-shadow-line-artifact
    A nasty artifact that can happen when casting shadow rays is the Shadow Line Artifact. Since shadow rays originate from a certain position and don't usually take the normal into account, a complete face on a smooth object will either be shadowed or not, revealing the hard edges again:

A Look at Ray Tracing in AMID EVIL: Shadows, Reflections, …

    Ray-traced reflections are easily noticeable with the pillars casting them on both the floor and the ceiling (upper right section of the image). The shadows are more subtle, primarily being cast on the lamp holders as the rails block the light, resulting in strong shadows on the outer surface.

Introduction to Shading (Light and Shadows) - Scratchapixel

    If you use ray-tracing, computing shadowing can be done while the main image is being rendered (it doesn't require to precompute a special image such as a shadow map). All we need to do is cast a ray from the object visible through a particular pixel of the frame, from the point of intersection to the light source.

Engineer’s Workshop: Enabling Ray-Traced Shadows in …

    Ray tracing creates the variance in shadows you’d expect to see generated by ambient outdoor lighting. In some places, shadows disappear altogether when the directional light is occluded. In the first image, the player is standing in a shadow cast by the wall, but casts no shadow themselves.
