  2. 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 ...

  3. Ray transfer matrix analysis - Wikipedia

    en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

    The ray tracing technique is based on two reference planes, called the input and output planes, each perpendicular to the optical axis of the system. At any point along the optical train an optical axis is defined corresponding to a central ray; that central ray is propagated to define the optical axis further in the optical train which need ...

  4. 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 ...

  5. 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 under a geometric optics approximation.

  6. Ray marching - Wikipedia

    en.wikipedia.org/wiki/Ray_marching

    Ray marching. Ray marching is a class of rendering methods for 3D computer graphics where rays are traversed iteratively, effectively dividing each ray into smaller ray segments, sampling some function at each step. For example, in volume ray casting the function would access data points from a 3D scan. In Sphere tracing, the function estimates ...

  7. Ray tracing (physics) - Wikipedia

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

    Ray tracing (physics) In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating analysis.

  8. Mathematical Applications Group - Wikipedia

    en.wikipedia.org/wiki/Mathematical_Applications...

    Mathematical Applications Group, Inc. (a.k.a. MAGi or MAGi/SynthaVision) was an early computer technology company founded in 1966 by Dr. Philip Mittelman and located in Elmsford, New York, where it was evaluating nuclear radiation exposure. By modeling structures using combinatorial geometry mathematics and applying monte carlo radiation ray ...

  9. Constructive solid geometry - Wikipedia

    en.wikipedia.org/wiki/Constructive_solid_geometry

    Ray tracing. Rendering of constructive solid geometry is particularly simple when ray tracing. Ray tracers intersect a ray with both primitives that are being operated on, apply the operator to the intersection intervals along the 1D ray, and then take the point closest to the camera along the ray as being the result. Applications
