1 Introduction. Brick maps were introduced in PRMan 12.0 as a 3D data structure for textures on surfaces and in volumes. PRMan 13.0 extended the use of brick maps to also allow their use as a geometric primitive (on equal footing with the other geometric primitives such as quadrics, polygon meshes, NURBS patches, and subdivision surfaces).
Up against the wall: creating realistic brick patterns in POV-Ray
http://shipbrook.net/jeff/raytrace/bricks.html
#declare P_RedBrickC = pigment { P_RedBrickB warp { repeat y*3 offset <60,0,0> } } In this instance, the pattern is repeated every three units along the Y axis (the default brick height), and the offset is a multiple of the brick's width (in this case, the default of 8) plus half the brick's width.I chose to offset it by the width of seven and one-half bricks, for a total offset of 60.
Ray tracing (graphics) - Wikipedia
https://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 from ray casting, recursive ray tracing, distribution ray tracing, photon mapping to ...

Ray tracing propagation model - MATLAB
https://www.mathworks.com/help/comm/ref/rfprop.raytracing.html
Ray tracing models: Are valid from 100 MHz to 100 GHz. Compute multiple propagation paths. Other propagation models compute only single propagation paths. Support 3-D outdoor and indoor environments. Determine the path loss and phase shift of each ray using electromagnetic analysis, including tracing the horizontal and vertical polarizations of ...
Ray Tracing for Windows | Minecraft
https://www.minecraft.net/en-us/updates/ray-tracing
Enabled by Minecraft’s Render Dragon graphics engine, ray tracing brings realistic lighting capabilities, such as global illumination and per pixel lighting, plus support for advanced textures to your world. Ray tracing is available for DirectX capable devices, such as GeForce RTX GPU and select AMD GPUs.
Geometrical Optics 101: Paraxial Ray Tracing Calculations
https://www.edmundoptics.com/knowledge-center/application-notes/optics/geometrical-optics-101-paraxial-ray-tracing-calculations/
Step 1: Enter Known Values. To begin, enter the known dimensional values of #49-849 into the ray-tracing sheet (Figure 2). Surface 0 is the object plane, Surface 1 is the convex surface of the lens, Surface 2 is the plano surface of the lens, and Surface 3 is the image plane (Figure 3). Remember that the curvature (C) ( C) is equivalent to 1 ...
Ray Tracing Depth Maps Using Precomputed Edge Tables

sections within a perspective depth map. The novel property of an edge table mask is that, given a planar light source perpendicular to the depth map’s axis of projection, the z-distances stored in the edge table mask can be used for any pixel in the depth map (due to the z-distances being unaffected by shearing in thexy plane of the depth map).
raytracing - How to map an image_map to a height_map …
https://stackoverflow.com/questions/55414851/how-to-map-an-image-map-to-a-height-map-in-pov-ray
After looking at this documentation, I concluded that I only needed to have something like. height_map { png "frame_height.png" // animation stuff redacted for brevity smooth texture { pigment { image_map { png "frame_texture.png" } } } } However, this doesn't map the pixels correctly. example: What I would like to happen, is for the blue ...
