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." Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games. Shadows are created by testing whether a pixel is visible from the light source, by comparing the pixel to a z-buffer or depth image of the light source's view, stored in the form of a texture.

  • Shadow map ou Mapeamento de sombra é uma técnica para criar sombras adicionada em imagens 3D produzidas por computação gráfica. Esse conceito foi introduzido por Lance Williams em 1978, em um paper com o título "Casting curved shadows on curved surfaces". Desde então vem sendo usada em cenas pré-renderizadas ou tempo-real em diversos consoles ou jogos de PC.As Sombras são criadas testando quando um pixel está visível a partir fonte de luz comparando isso com o z-buffer ou com a visão de profundidade da imagem segundo a fonte de luz, guardada na form de textura.
  • 阴影贴图(Shadow mapping)是在三维计算机图形中加入阴影的过程。阴影贴图的概念最初是由 于 1978年在“在曲面上投射阴影”这篇论文中提出的。从那时开始,这种方法就已经用于场景预渲染、实时甚至是许多游戏设备以及高端电脑游戏中。在Pixar 的 RenderMan 中就使用了阴影贴图技术,同样,在 玩具总动员 这样的游戏中也使用了这项技术。 像素与以纹理形式保存的光照深度缓冲区或者深度图像比较,通过这种方式计算像素是否处于光源照射范围之内,从而生成阴影。
  • Shadow Mapping ist eine Methode der Computergrafik, um Schattenwurf darzustellen. Das Konzept wurde 1978 im Paper "casting curved shadows on curved surfaces" von Lance Williams vorgestellt. Shadow Maps werden sowohl für Offlinerendering als auch für Echtzeitanwendungen benutzt.
  • Shadow mapping o projective shadowing è un processo con il quale vengono calcolate e renderizzate le ombre nella computer grafica 3D. Il concetto è piuttosto vecchio e risale ad un articolo di del 1978 intitolato "Casting curved shadows on curved surfaces" (trad.: 'gettare ombre curve su superfici curve'). Da allora la tecnica viene utilizzata sia per i rendering pre-calcolati che per le scene realtime, soprattutto nei videogiochi. Lo shadow mapping viene utilizzato anche in produzioni cinematografiche, e fa parte dell'engine RenderMan della Pixar che lo ha utilizzato in film come Toy Story.
  • Метод теневых карт (англ. Shadow mapping) или карт теней — способ моделирования теней в трёхмерной компьютерной графике. Этот способ используется при создании как пререндеренных, так и анимируемых в реальном времени трехмерных сцен и широко применяется в киноиндустрии и компьютерных играх. Концепция теневых карт была введена американским специалистом по компьютерной графике Лэнсом Уильямсом в 1978 году в статье под названием «Отбрасывание изогнутых теней на изогнутые поверхности» (англ. «Casting curved shadows on curved surfaces»).
