NAME

ae - Sets the view orientation for the mged display by rotating the eye position about the center of the viewing cube.

SYNOPSIS

ae [-i] {azimuth} {elevation} [twist]

DESCRIPTION

Set the view orientation for the mged display by rotating the eye position about the center of the viewing cube. The eye position is determined by the supplied azimuth and elevation angles (degrees). The azimuth angle is measured in the xy plane with the positive x direction corresponding to an azimuth of 0°. Positive azimuth angles are measured counter-clockwise about the positive z axis. Elevation angles are measured from the xy plane with +90° corresponding to the positive z direction and -90 corresponding to the negative z direction. If an optional twist angle is included, the view will be rotated about the viewing direction by the specified twist angle. The -i option results in the angles supplied being interpreted as increments.

EXAMPLES

The examples show how to change views by entering azimuth and elevation angles, adding a twist angle, and having the angles supplied being treated as increments.

Example 1. Top view

mged> ae -90 90

Example 2. Right-hand side view

mged>ae 270 0

The view is from the right-hand side.

Example 3. View from a specific azimuth and elevation with a twist angle.

mged>ae 35 25 10

The view is from azimuth 35, elevation 25, with a view rotated by 10 degrees.

Example 4. The azimuth and elevation angles supplied are treated as increments.

mged>ae -i 0 0 5

Rotates the current view through 5 degrees about the viewing direction.
