Ray-Traced Shadows — Blender Manual
https://docs.blender.org/manual/en/2.79/render/blender_render/lighting/shadows/raytraced_properties.html
This slider sets the maximum number of samples that both Constant QMC and Adaptive QMC will use to do their shadow calculations. The maximum value is 16: the real number of samples is actually the square of it, so setting a sample value of 3 really means 3 2 = 9 samples will be taken. Soft Size Light size for ray shadow sampling.
Ray Traced Light Area Shadows and Denoising - YouTube
https://www.youtube.com/watch?v=26YxOt-L1kQ
Why would you use ray tracing for shadows, instead of shadow meshes? What are the different kinds of denoisers used for ray tracing? Edward gives you the ans...
c++ - Raytracing Shadows - Stack Overflow
https://stackoverflow.com/questions/25942554/raytracing-shadows
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 intersection is found, there is no need to search for another. My guess is that your shadow flag is set to …
Shadow rays in Raytracing - Computer Graphics Stack Exchange
https://computergraphics.stackexchange.com/questions/1734/shadow-rays-in-raytracing
In a one-hit tracer, you can't fix that problem by simply discarding the intersection, because you still don't know whether the shadow ray would have intersected another object further along. To avoid self-intersections, you need to push the start point of the ray along its direction by epsilon:
Ray Traced Shadows - UE4 Materials 101 - Episode 42

This video covers the topic of Shadows in Unreal Engine. First we discuss a couple of weaknesses with the standard light map method for rendering shadows. T...
raytracing - Ray Tracing Shadows: The Shadow Line Artifact
https://computergraphics.stackexchange.com/questions/4986/ray-tracing-shadows-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: The shadow is, so to speak, 'correct' and the weird appearance results from the normal map interpolation 'cheat'.
Rendering soft shadows - Ray Tracer Challenge
http://raytracerchallenge.com/bonus/area-light.html
The next step is to take your intensity_at function and plug it into the rest of your ray tracer. You'll do this by updating your lighting () function so it can handle a fractional intensity instead of a boolean "is shadowed" value. Here's the test: materials.feature
A Look at Ray Tracing in AMID EVIL: Shadows, Reflections, …

Although the overall impact is still fairly limited, the shadows are much sharper with ray-tracing enabled and thin/smaller objects cast more accurate and detailed shadows (such as the pattern on the ground). Normally, shadows are somewhat softer but in this case, they are pretty sharp here due to the brute-force approach.
Introduction to Shading (Light and Shadows) - Scratchapixel

Thus, we first trace a camera or primary ray, then find an intersection point (the surface that is visible for the pixel from which the primary ray was cast) and then trace a shadow ray from that point of intersection to the light. The difference between what happens in nature, and how we compute shadows in CG is shown in figure 2.
Ray traced soft shadows in real time in Spellwrath - Imagination
https://blog.imaginationtech.com/ray-traced-soft-shadows-in-real-time-spellwrath/
After we have scored a hit in our ray tracer, the following steps are taken to trace the shadows: For each pixel hit on the screen (2D), we cast a ray from it’s actual 3D position in world space towards the light source If the pixel is occluded, we store our occlusion value If the pixel is not occluded, we store a value of 1.0 in the buffer
