Ray Trace Parameters - Lighting Analysts

    https://docs.agi32.com/AGi32/Content/ray_tracing/Ray_Trace_Parameters.htm
    The Ray Trace Parameters dialog is used to specify the parameters used to generate Ray Trace images in AGi32. From the Control Bar select . To modify the Raytrace parameters, choose the Set Parameters option from the Raytrace secondary menu. General tab Number of Bounces This value indicates the maximum number of specular bounces for each ray.

What is Ray Tracing and How Does It Work? | Synopsys

    https://www.synopsys.com/glossary/what-is-ray-tracing.html
    Ray tracing makes it possible to determine the quality of the rendered image for image-forming systems, the distribution of light for illuminations systems, and much more. Ray tracing, combined with optimization of the optical system parameters, can automatically improve the imaging or illumination performance, to achieve desired goals.

Ray Tracing - an overview | ScienceDirect Topics

    https://www.sciencedirect.com/topics/earth-and-planetary-sciences/ray-tracing
    The basic procedure of ray tracing is as follows: fire a large number of “photon packs” toward the simulated microstructure; track the individual “photon” until it goes out of boundary or be absorbed; gather the “photon packs” in the hemisphere of simulated bicontinuous medium. The firing of “photons” can be assumed as the incident energy toward the snow surface.

Fundamentals of Ray Tracing

    At any point along a ray, we can express the ray in terms of its horizontal and vertical slownesses (Figure 2), pand = cos (z) v(z) = p v2(z) p2; (3) 1. v z Increasing range (X) p decreasing (take off angle decreasing) Figure 1: Rays in media of increasing velocity with depth. Generally X increases as p decreases.

Tracing — Ray 1.12.0

    To run using this default hook, you can run the following code sample to set up tracing and trace a simple Ray task. ray start $ ray start --head --tracing-startup-hook = ray.util.tracing.setup_local_tmp_tracing:setup_tracing $ python >>> ray.init ( address = "auto" ) >>> @ray.remote def my_function () : return 1 obj_ref = my_function.remote ()

Geometrical Optics 101: Paraxial Ray Tracing Calculations

    https://www.edmundoptics.com/knowledge-center/application-notes/optics/geometrical-optics-101-paraxial-ray-tracing-calculations/
    Paraxial ray tracing by hand is typically done with the aid of a ray-tracing sheet (Figure 1). The number of optical lens surfaces is indicated horizontally and the key lens parameters vertically. There are also sections to differentiate the marginal and chief ray. Table 1 explains the key optical lens parameters.

Ray-Tracing: Generating Camera Rays (Definition of a Ray)

    https://www.scratchapixel.com/lessons/3d-basic-rendering/ray-tracing-generating-camera-rays
    Ray-tracing is a technique used to compute the visibility between points. It is simply a technique based on the concept of ray which can be mathematically (and in a computer program) defined as a point (the origin of the ray in space) and a direction.

    c,z. c) and radius R can be represented as: (x-x. c) + (y-y. c) + (z-z. c) - R = 0 For a point pon the sphere, we can write the above in vector form: (p-c). (p-c) - R = 0 (note ‘.’ is a dot product) We can plug the point on the ray p(t) = e+ t d. (e+td-c). (e+td-c) - R = 0 and yield (d.d) t + 2d.

raytracing - How to calculate ray - Computer Graphics ...

    https://computergraphics.stackexchange.com/questions/8479/how-to-calculate-ray
    In ray-tracing technique critical point is to calculate rays which came out from eye E to target T through pixel P i j on viewport. The "viewport" is represented as rectangle divided to square pixels - this rectangle is perpendicular to line which go through points E, C (viewport center) and T.

Ray transfer matrix analysis - Wikipedia

    https://en.wikipedia.org/wiki/Ray_transfer_matrix_analysis
    Ray transfer matrix analysis (also known as ABCD matrix analysis) is a mathematical form for performing ray tracing calculations in sufficiently simple problems which can be solved considering only paraxial rays.
