Drawing modes

A view can display a scene in 10 modes:
  • wire frame, parallel (or isometric) projection, backside visible
  • wire frame, perspective projection, backside visible
  • wire frame, parallel (or isometric) projection, backside not visible
  • wire frame, perspective projection, backside not visible
  • wire filled, parallel (or isometric) projection
  • wire filled, perspective projection
  • flat shaded, perspective projection
  • gouraud shaded, perspective projection
  • silhouette, perspective projection
  • UV projected
   
The difference between the isometric projection and perspective projection is explained in the following picture:
In perspective projection, the on screen size of an object is related to the distance between the view point and the object. Far objects are smaller than near objects. This is a simplify model of a camera. But, it is useful to view the object with a size not related to its distances from the view point. That the purpose of the isometric projection. Most of the time, when modelling object, the isometric projection is used.

When a view has the keyboard focus, the drawing mode can be changed with:
