查询词典 mapping theorem

For specific object searching, the amount of redundant information, which is acquired by uniform sampling sensor, will cost much computer time. The mapping between the retina of human eye and the striate cortex can be approximated by a log-polar coordinate mapping.

Carl Ludwing explains how this technique differs from traditional texture mapping : when you want something to be in a certain area, like a grease spot, everyone else tends to do it with standard texture-mapping tools. But if I take a painted map and map it on, then I've wrapped a two-dimensional object around a three-dimensional object, and there are all sorts of positioning problems associated with that. Also, when you transition to another subpart of the character, you have to provide a whole new set of coordinates.

卡尔·路德温解释了这一技术与传统材质贴图技术的不同之处，比如说：如果想把油点一类的东西贴到某个地方，别人都会用标准的材质贴图工具来完成，但是如果我先拿来一张着色的地图，把这个油点标在上面，那就等于把一个三维物体安置在二维环境当中，随之会出现各种定位方面的问题，同样，如果你要观察目标的另一处次要部位，就必须给出新的坐标。

Surveying and mapping the value of work lies in the application of surveying and mapping results.

It is revealed that in the condensates, the different configurations of order parameters lead to different topological structures-velocity field vortex lines, Mermin-Ho vortex lines and monopoles, and these three topological structures can all be characterized by the Hopf indices and Brouwer degrees of φ-mapping, and their locations and motions also be rigorously determined by φ-mapping theory.
