术语 | projection plane |
释义 | projection plane 投影平面 In computer cartography, in general, the output of three dimensional graphic object is expressed as two dimensional graphs, i.e. projecting it on a plane and turning the view plane into image output on the output interface. This plane is called a projection plane, and specified by three parameter: view reference point, view plane normal and view plane distance. 在计算机制图技术[卡通]中,三维图形对象的输出一般是采用三维对象的二维表示进行处理的,即将三 维图形先投影在一个平面上,然后再将投影的图形转化成输出界面上的图象输出。这一平 面称为投影平面,它由视见参考点、投影平面法向和投影平面距离这三个参数规定。 |
