2. Path tracing - Wikipedia

   en.wikipedia.org/wiki/Path_tracing

   The central performance bottleneck in path tracing is the complex geometrical calculation of casting a ray. Importance sampling is a technique which is motivated to cast fewer rays through the scene while still converging correctly to outgoing luminance on the surface point.

3. Reflection (computer graphics) - Wikipedia

   en.wikipedia.org/wiki/Reflection_(computer_graphics)

   Ray-traced model demonstrating specular reflection. Reflection in computer graphics is used to render reflective objects like mirrors and shiny surfaces. Accurate reflections are commonly computed using ray tracing whereas approximate reflections can usually be computed faster by using simpler methods such as environment mapping.

4. Computer graphics lighting - Wikipedia

   en.wikipedia.org/wiki/Computer_graphics_lighting

   Ray tracing solves this problem by reversing the process, instead sending view rays from the observer and calculating how they interact until they reach a light source. [24] Although this way more effectively uses processing time and produces a light simulation closely imitating natural lighting, ray tracing still has high computation costs due ...

5. Ray tracing (physics) - Wikipedia

   en.wikipedia.org/wiki/Ray_tracing_(physics)

   Ray tracing of a beam of light passing through a medium with changing refractive index.The ray is advanced by a small amount, and then the direction is re-calculated. Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (), and that there exists some distance, possibly very small, over which such a ray is locally straight.

6. Unbiased rendering - Wikipedia

   en.wikipedia.org/wiki/Unbiased_rendering

   An unbiased technique, like path tracing, cannot consider all possible light paths due to their infinite number. It may not select ideal paths for a given render , as this would introduce bias. For example, path tracing struggles with caustics from a point light source because it is unlikely to randomly generate the exact path needed for ...

7. Light transport theory - Wikipedia

   en.wikipedia.org/wiki/Light_transport_theory

   While wave-based models rely on the principles of Maxwell's equations, particle models use ray optics and Monte Carlo methods to simulate light paths. Monte Carlo Ray Tracing: A stochastic method used in light transport simulations to compute global illumination. This method leverages randomness to estimate solutions to the rendering equation ...

8. Ray tracing (graphics) - Wikipedia

   en.wikipedia.org/wiki/Ray_tracing_(graphics)

   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. (c. 2008) In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.

   English: A 3D rendered image using path tracing, rendered by Blender's Cycles renderer. The smoothness of the meshes used for the cows has been increased using subdivision . The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination when comparing to versions of the ...
