Two pictures to show the effect of a 45 degree tilt
View from 10 5 3 to 12 20 4 with 45 degree tilt
The first picture is identical to the second, with all the lines rotated by 45 degrees clockwise (tilt of view is measured clockwise).
Red blue and cyan lines are translations of the x, y and z axes respectively to the point 12 20 4.
Viewpoint for second one is
Viewpoint
{
description "Looking towards point 12 20 4, and no tilt of view"
position 10 5 3
orientation -0.374199 0.702414 -0.605466 -2.32246
fieldOfView 0.785398
}
Viewpoint for first one is
Viewpoint
{

position 10 5 3
orientation -0.0714183 0.735562 -0.673683 -2.82961
fieldOfView 0.785398
}
N.B. If you change the sign of all the numbers in the orientation, the effect is the same, so the first one could also be shown as
