Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces." [1] Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games.
Vantablack [ 1][ 2] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% [ 4] in the visible spectrum. The name is a portmanteau of the acronym VANTA ( vertically aligned nanotube arrays ...
The idea of deferred shading was originally introduced by Michael Deeringand his colleagues in a paper[3]published in 1988 titled The triangle processor and normal vector shader: a VLSI system for high performance graphics. Although the paper never uses the word "deferred", a key concept is introduced; each pixel is shaded only once after depth ...
The partial transparency and reflection of the water in the foreground are added by a shader applied finally to the entire scene. The High-Level Shader Language [1] or High-Level Shading Language [2] ( HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to ...
Money market funds’ net assets reached $6.4 trillion in 2023, with investors pouring a record $1.2 trillion into the funds during the year, according to the U.S. Treasury Department’s Office ...
A farmer in Wales had a field that just made life too difficult. He was continually hitting slate and stone. It turns out, there was a good reason for all the struggle: a buried Roman fort. Mark ...
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 ...
Patients with type 2 diabetes taking GLP-1 treatments, which include Ozempic, have a lower chance of developing 10 types of obesity-related cancers than those taking insulin and other diabetes ...
