和360不規則的物體就有相當的困難度,點擊成型的茶壺並不是為了實用,今天: 3d studio MAX 用茶壺是有個典故的。所以,做個茶壺(不是靠藝術,好像還舉行過作茶壺的比賽,但對於曲線。80年代底的時候,而是主要依靠程序)是有難度的。對於那個時候的程序來說,對於有中心的對稱幾何體還行,那個時候的三維工具都像鈍刀。當3d studio max 還只是 3d max 的時候茶壺是最能體現出3D處理效果的 ---以前學的時候老師這麼說的

Utah teapot The teapot shape contains a number of elements that made it ideal for the graphics experiments of the time: it is round, contains saddle points, has a genus greater than zero because of the hole in the handle, can project a shadow on itself, and looks reasonable when displayed without a complex surface texture. 程序生成,又不至於太簡單,有方向性,做各種渲染和動畫測試很好。
今天剛剛在矽谷的Computer History Museum圍觀到了這傢伙的本尊,以下照片為本人親手所拍,詳細解釋可以看展品說明
1975 A.D -Martin Newell , working at the Utah University ,develops a three-dimensional of a teapot ,the same model that we associate nowadays with the concept of Computer Graphics. For his experiments, Martin needs a simple mathematic model, but not too simple.Thus he refers to the famous tea-port.
Figure2.200 The original tea-pot which inspired him is now kept in the Computer History Museum in Mountain View, California.
