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: glm::vec3 direction = normalize (ldir); glm::vec3 ...
Introduction to Ray Tracing: a Simple Method for Creating 3D …

The ray-tracing algorithm takes an image made of pixels. For each pixel in the image, it shoots a primary ray into the scene. The direction of that primary ray is obtained by tracing a line from the eye to the center of that pixel.

Ray Tracing: shading 1 • With eye ray generation and scene intersection for 0 <= iy < ny for 0 <= ix < nx { ray = camera.getRay(ix, iy); ... (shadow ray not blocked) { result += shading contribution; } } return result; } 15 • Intensity depends on view direction
c++ - Raytracing Shadows - Stack Overflow
https://stackoverflow.com/questions/25942554/raytracing-shadows
Vector intersect = r.getOrigin () + r.getDirection ()*t; When you calculate the intersection point, you use t instead of t_min. The fix consists in changing the above line to: Vector intersect = r.getOrigin () + r.getDirection ()*t_min; The correct output is the following:
What is a shadow ray? - Blender Stack Exchange
https://blender.stackexchange.com/questions/23500/what-is-a-shadow-ray
When the light path begins, it starts as a camera ray, when it's reflected it becomes a reflection ray, when it goes through glass it becomes a transmission ray and from the last point to a lamp it is a shadow ray. These are the 4 base types of rays …
Ray tracing: shadow ray path calculation question
https://www.reddit.com/r/GraphicsProgramming/comments/ib2kqu/ray_tracing_shadow_ray_path_calculation_question/
This technique first traces rays from light sources towards refractive objects, and stores the results of the refraction in a 'photon map' - typically a k-d tree built around the geometry of your scene. Then when the regular ray-tracer fires rays from the camera, it samples the photon-map to add the stored caustics energy to the ray. 1 level 1
Lecture 2: Introduction to Ray Tracing
https://inst.eecs.berkeley.edu/~cs294-13/fa09/lectures/scribe-lecture1.pdf
The shadow is computed by creating shadow rays which originates from the intersection to all lights. If the shadow ray intersects an object before it reaches the light, then that intersection point is shadowed from that particular light. 1.3 Advantage/Disadvantage The main advantage of ray tracing is its realitic rendering of re

raytracing - European Synchrotron Radiation Facility
https://www.esrf.fr/Instrumentation/software/data-analysis/OurSoftware/raytracing
A very powerful approach to predict the performance of an optical system in general, and a synchrotron radiation beamline in particular is the use of ray tracing methods. For synchrotron radiation applications, the code SHADOW has been used extensively for designing and optimizing syncrhotron radiation beamlines during the last 20 years.
