犹他茶壶

用现代手段渲染的犹他茶壶,建模者是 马丁·纽维尔 (1975).
The actual Melitta teapot that Martin Newell modelled. Residing at The Computer Museum, Boston (1984–1990).
As displayed at the Computer History Museum in Mountain View, California (1990–present).

犹他茶壶英语:Utah teapot),或称纽维尔茶壶Newell teapot),是在计算机图形学界广泛采用的标准参照物体(有时也是个内行幽默)。其造型来自于生活中常见的造型简单的茶壶,被制成数学模型,外表为实心、柱状和部分曲面。

以一个茶壶作为基本物体的想法,与计算机进程设计领域里的“Hello World”进程如出一辙。目的是,方便快捷地创建一个最简单的三维场景,使其含有相对复杂的模型,以此模型为基本参考几何物体,用以辅助安排场景和设定灯光。

有许多库甚至包含专门用来绘制茶壶的函数。

这个茶壶的模型是在1975年由早期的计算机图形学研究者马丁·纽维尔(Martin Newell)制作的,他是犹他大学先锋图形项目小组的一员。

Utah teapot 犹他茶壶

A modern rendering of the Utah teapot model.
The actual Melitta teapot that Martin Newell modelled. Residing at The Computer Museum, Boston (1984–1990).
As displayed at the Computer History Museum in Mountain View, California (1990–present).

The Utah teapot, or the Newell teapot, is a 3D computer model that has become a standard reference object (and something of an in-joke) in the computer graphics community. It is a mathematical model of an ordinary teapot of fairly simple shape, that appears solid, cylindrical and partially convex. A teapot primitive is considered the equivalent of a "hello, world" program, as a way to create an easy 3D scene with a somewhat complex model acting as a basic geometry reference for scene and light setup. Many programming libraries even have functions dedicated to drawing teapots.
