查询词典 projection method

The dissertation mainly studied the key techniques which are the mathematics modeling of cone-beam CT simulation system, and the parallel rapid simulation of the projection imaging with STL phantom models. Then a cone-beam CT simulation system platform was developed, which provided the projection simulation for compounding phantoms, non-point X-ray source and multiple X-ray spectrums.

The modelview transform is used in the same way as it is in the OpenGL viewing pipeline, to move the viewer to the origin and the projection centered along the negative z axis. In this case, viewer can be thought of a light source, and the near clipping plane of the projection as the location of the texture image, which can be thought of as printed on a transparent film.

模型/视图变换的作用和它在OpenGL 观察管道里的作用是一样的，它将观察者沿-Z方向移动到原点和投影中心，在这种情况下，观察者就好比是是光源，近裁剪平面好比是需要投影的纹理图象的所处的位置，纹理图象可以被看作一个在投影的透明胶片。
