Stereopair Rotation
Previous  Top  Next

Dialog Box - called from: Rotation Menu

If you want to show a steropair which can fit onto one page, it is usually easiest to draw it automatically by turning on the stereopair mode with the Stereopairs dialog in the Input2 menu. However, you may want to set up and draw each half of the pair manually, if for example each view is to take up an entire page of output. This option rotates the structure and the illumination vector for shading by the requested angle about the z axis. If you are not using shading, ordinary rotation about z (viewer) will suffice.

The left-eye view should be rotated clockwise (positive angle): an angle of about +3 degrees is usually satisfactory, although this may depend on the perspective distance, the type of viewing device, etc. After making a hard copy of this orientation, the rotation should be negated with the Remove button. Then make a right-eye view by rotating the negative of the left-eye value; after making the hard-copy, remove the rotation again.
