WebPerspective - The view of the scene can be Perspective or Orthographic. In the perspective view (the default), objects which are far away are smaller than those near by. In the orthographic view, both objects appear at the same scale. Note that several of the supported external rendering programs do not support orthographic rendering. WebAn orthographic projection matrix directly maps coordinates to the 2D plane that is your screen, but in reality a direct projection produces unrealistic results since the projection doesn't take perspective into …
