Ray tracing and shading

Smooth specular reflection/refraction (e.g. chrome, glass, glaze/varnish) - light reflected/refracted only in a single direction - colored by source color. 15. ... Basic Ray Tracing Pipeline. 39. Intersection. Shading. Ray Generation. specular object light reflects towards only one direction.
Ray Tracing (Shading)
https://www.cs.cornell.edu/courses/cs4620/2012fa/lectures/35raytracing.pdf
Ray tracing dielectrics •Like a simple mirror surface, use recursive ray tracing •But we need two rays –One reflects off the surface (same as mirror ray) –The other crosses the surface (computed using Snell’s law) •Doesn’t always exist (total internal reflection) •Splitting into two rays, recursively, creates a ray tree
Ray Tracing: shading - Cornell University

Ray Tracing: shading 1 • With eye ray generation and scene intersection for 0 <= iy < ny for 0 <= ix < nx { ray = camera.getRay(ix, iy); c = scene.trace(ray, 0, +inf); ... (shadow ray not blocked) { result += shading contribution; } } return result; } 15 • Intensity depends on view direction
Introduction to Shading (Normals, Vertex Normals and …
https://www.scratchapixel.com/lessons/3d-basic-rendering/introduction-to-shading/shading-normals
Vertex normals are used in a technique called smooth shading that you will find described at the end of this chapter. For now, we will only deal with face normals. ... Computing the viewing direction is also very simple. When ray-tracing is used, it is simply the opposite direction of the ray that intersected the surface at \(P\). In you don't ...
raytracing - Ray Tracing Shadows: The Shadow Line Artifact
https://computergraphics.stackexchange.com/questions/4986/ray-tracing-shadows-the-shadow-line-artifact
By using smooth shading (i.e. interpolation of normals), an object can have a smooth look despite low polygon count. 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 …
Smooth Shading

The donut on the right has a much higher complexity, with 11,680 faces. The two outside shapes are being rendered with flat shading, while the central one is being smoothed. In spite of the large number of polygons in the rightmost torus, it is visibly faceted (click to zoom the view). Our eyes turn out to be good at spotting edges!
Practical Tips for Implementing Subsurface Scattering in …
https://agraphicsguynotes.com/posts/practical_tips_for_implementing_subsurface_scattering_in_a_ray_tracer/
Importance sampling of BSSRDF involves two things, sampling an incoming direction and sampling a position where the incoming light enters the volume of the SSS object from the surface. Sampling a direction is no different from sampling a direction using BRDF. As a matter of fact, PBRT uses a wrapper BXDF to hide the.
3d - Ray tracing - soft shadow - Stack Overflow
https://stackoverflow.com/questions/31709332/ray-tracing-soft-shadow
Generate a set of M random, uniform shadow rays from P towards disc D. If a ray R intersects anything before hitting L, there is no energy transfer along this path. Otherwise: multiply E/M by a dot product of normal vector N at P and (normalized) R, add the result to the light transferred so far. Repeat for all M rays.
Ray tracing tutorial - section 2: diffuse shading
https://www.groovyvis.com/other/raytracing/diffuse.html
The method of ray tracing commonly used is called backward ray tracing because it follows the path of vision. ... Diffuse shading is based on the principal that more light hits the surface of an object where the angle between the surface normal and the vector from the intersection to The light is least. ... with a smooth gradient between those ...

This application note is focused on the ray-traced shading features of the renderer. Ray tracing fits into Pixar's RenderMan as an additional tool to help shader writers be more productive and create very specific special effects. ...
