   Some words about parallel and perspective projection:
   Though we have a 3D world eventually when we create an image
   of that world it is a 2D image. In order to get this image the engine
   projects the 3D world onto a projection plane. There are two main methods to do this projection
   They are called parallel projection and perspective projection.
   Perspective projection (the default ) is similar to the way the human
   eye sees things. Far away objects look smaller while closer objects look bigger.
   Parallel projection is the same as orthographic projection.
   The depth dimension is not shown on the result image.
   If you never heard of projection method simply try both method
   and see what happens. For the vast majority of applications
   you will use only perspective projection (the default)
   Parallel projection should interest you only if your application is in fields such as
   Architecture design, 3D modeling etc ...
   Parallel projection has little use in games if at all.
