The coordinate system, for 2-d graphics, is shown in Figure 2.
2 - D图形的坐标系如图2所示。

Most traditional graphics languages use a "virtual" coordinate system with horizontal and vertical axes that range (for instance) from 0 to 32,767.
大多数传统的图形语言用具有范围(例如)从0到32,767的水平和垂直轴的“虚”坐标系统。

Parallel projection of the affine coordinate system has a significant impact on computer graphics recognition, object's tracking or solid model reconstruction.
