2. Ray transfer matrix analysis - Wikipedia

   en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

   A light ray enters a component crossing its input plane at a distance x 1 from the optical axis, traveling in a direction that makes an angle θ 1 with the optical axis. After propagation to the output plane that ray is found at a distance x 2 from the optical axis and at an angle θ 2 with respect to it.

3. Ray tracing (graphics) - Wikipedia

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

   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 . On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...

4. Constructive solid geometry - Wikipedia

   en.wikipedia.org/wiki/Constructive_solid_geometry

   Constructive solid geometry ( CSG; formerly called computational binary solid geometry) is a technique used in solid modeling. Constructive solid geometry allows a modeler to create a complex surface or object by using Boolean operators to combine simpler objects, [1] potentially generating visually complex objects by combining a few primitive ...

5. Möller–Trumbore intersection algorithm - Wikipedia

   en.wikipedia.org/wiki/Möller–Trumbore...

   The Möller–Trumbore ray-triangle intersection algorithm, named after its inventors Tomas Möller and Ben Trumbore, is a fast method for calculating the intersection of a ray and a triangle in three dimensions without needing precomputation of the plane equation of the plane containing the triangle. [1] Among other uses, it can be used in ...

7. Rendering equation - Wikipedia

   en.wikipedia.org/wiki/Rendering_equation

   The rendering equation describes the total amount of light emitted from a point x along a particular viewing direction, given a function for incoming light and a BRDF. In computer graphics, the rendering equation is an integral equation in which the equilibrium radiance leaving a point is given as the sum of emitted plus reflected radiance ...
