Ray tracing (graphics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(graphics)
Ray tracing (graphics) Not to be confused with Ray tracing (physics). This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a ...

In a 1979 paper entitled “An Improved Illumination Model for Shaded Display”, Turner Whitted was the first to describe how to extend Appel’s ray-tracing algorithm for more advanced rendering. Whitted’s idea extended Appel’s model of shooting rays to incorporate computations for both reflection and refraction. 【扩展光线追踪 ...

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 simulating glass materials or mirror surfaces.In a 1979 paper entitled "An Improved Illumination Model for Shaded Display", Turner Whitted was the first to describe how to extend Appel's ray-tracing algorithm …

Reflections and Refractions in Ray Tracing Bram de Greve ([email protected]) November 13, 2006 Abstract When writing a ray tracer, sooner or later you’ll stumble on the problem of reflection and transmission. To visualize mirror-like objects, you need to reflect your viewing rays. To simulate a lens, you need refraction. While most ...
Reflections and Refractions in Ray Tracing
https://www.researchgate.net/publication/228959915_Reflections_and_Refractions_in_Ray_Tracing
According to Whitted [4], the Ray Tracing rendering method can simulate shadows, true reflection and refraction. The latter two were also investigated by de Greve [5] while writing a ray tracer ...

17 Shading with reflection Let I(P, d) be the intensity seen along a ray.Then: I(P, d) = I direct + I reflected where I direct is computed from the Blinn-Phong model, plus shadow attenuation I reflected = k r I (Q, R) Typically, we set k r = k s.(kr is a color …
CS 410 Assignment 04 - Ray Tracing with Reflection and …
https://www.cs.colostate.edu/~cs410/yr2013fa/more_assignments/assignment04.php
In this assignment you will implement recursive ray-tracing for both reflection and refraction. Previously, in the ray cast command ‘r’ the recursion depth value was included but not used. In this assignment you will use it for recursive ray tracing. In the previous assignment, the illumination for a point on surface was defined by the sum ...

• Combines eye ray tracing + rays to light and recursive tracing • Algorithm: 1. For each pixel, trace primary ray in direction V to the first visible surface. 2. For each intersection trace secondary rays: • Shadow in direction L to light sources • Reflected in direction R • Refracted (transmitted) in direction T 3. Calculate shading ...

Reflections and Refractions in Ray Tracing Bram de Greve ([email protected]) 10th October 2004 When you’re writing a ray tracer, soon or late you’ll stumble on the problem of re-flection and refraction. When you want to visualize mirror-like objects, you need to reflect our viewing ray. To simulate a lens, you need refraction.
