NAME

eqn - Allows the user to rotate the face of an ARB shape by providing the coefficients of an equation of the desired plane for the face.

CONTENTS

SYNOPSIS

eqn {A B C} []

DESCRIPTION

Allows the user to rotate the face of an ARB shape by providing the coefficients of an equation of the desired plane for the face. The coefficients A, B, and C are from the plane equation:

Ax + By + Cz = D

The user must be editing an ARB shape and be rotating a face of the ARB for this command to have any effect. When entering such a state, the user will be asked which of the face vertices should be held constant, and from this information the D coefficient of the equation is determined.

EXAMPLES

The example shows the use of the eqn command to rotate the face of the ARB being edited to be parallel to the xy plane.

Example 1. Rotate the face of an ARB to be parallel to the xy plane.

mged> eqn 0 0 1

The face of the ARB is rotated to be parallel to the xy plane.

Example 2.
