  2. Ray tracing (graphics) - Wikipedia

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

    Scanline algorithms and other algorithms use data coherence to share computations between pixels, while ray tracing normally starts the process anew, treating each eye ray separately. However, this separation offers other advantages, such as the ability to shoot more rays as needed to perform spatial anti-aliasing and improve image quality ...

  3. Ray-tracing hardware - Wikipedia

    en.wikipedia.org/wiki/Ray-tracing_hardware

    The ray tracing algorithm is inherently suitable for scaling by parallelization of individual ray renders. [3] However, anything other than ray casting requires recursion of the ray tracing algorithm (and random access to the scene graph ) to complete their analysis, [ 4 ] since reflected, refracted, and scattered rays require that various ...

  4. Slab method - Wikipedia

    en.wikipedia.org/wiki/Slab_method

    In computer graphics, the slab method is an algorithm used to solve the ray-box intersection problem in case of an axis-aligned bounding box (AABB), i.e. to determine the intersection points between a ray and the box.

  5. Ray tracing - Wikipedia

    en.wikipedia.org/wiki/Ray_tracing

    Ray tracing is a method for calculating the path of waves or particles through a system. The method is practiced in two distinct forms: The method is practiced in two distinct forms: Ray tracing (physics) , which is used for analyzing optical and other systems

  6. 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]

  7. 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.

  8. Ray marching - Wikipedia

    en.wikipedia.org/wiki/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 a distance to ...

  9. Monte Carlo method - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method

    Path tracing, occasionally referred to as Monte Carlo ray tracing, renders a 3D scene by randomly tracing samples of possible light paths. Repeated sampling of any given pixel will eventually cause the average of the samples to converge on the correct solution of the rendering equation , making it one of the most physically accurate 3D graphics ...
