Set the View Projection Mode
View projection produces realistic visual effects of a model.
The ViewCube tool supports two view projection modes (Perspective and
Orthographic) and a combination of both these modes (Perspective with Ortho
faces). Orthographic projection is also referred to as parallel projection.
Perspective projected views are calculated based on the distance from a
theoretical camera and target point. The shorter the distance between the
camera and the target point, the more distorted the perspective effect appears;
greater distances produce less distorted affects on the model. Orthographic
projected views display all the points of a model being projected parallel to
the screen.
Orthographic projection mode makes it easier to work with a model due to
all the edges of the model appearing as the same size, regardless of the distance
from the camera. Orthographic projection mode though, is not how you
commonly see objects in the real world. Objects in the real world are seen in
perspective projection. So when you want to generate a rendering or hidden
line view of a model, using perspective projection will give the model a more
realistic look.
