point. Small distances produce severe perspective effects; large distances
produce mild effects.
The following illustration shows the same model in both a parallel projection
and perspective projection. Both are based on the same viewing direction.
Define a Perspective Projection (DVIEW)
Perspective projections require a distance between a theoretical camera and
a target point. Small distances produce severe perspective effects; large distances
produce milder effects.
A perspective view remains in effect until the perspective effect is turned off
or until a new view is defined in its place.
Define a Parallel Projection
You can define a parallel projection.
To determine the point or angle in model space, you can
Enter a coordinate or angles that represent your viewing location in 3D.
Change to a view of the XY plane of the current UCS, a saved UCS, or the
WCS.
Change the 3D view dynamically with your pointing device.
