| * This package provides components related to rotations in 3 dimensional |
| * Euclidean space. |
| * </p> |
| * |
| * <h2>Conventions</h2> |
| * <p> |
| * There are numerous conventions that must be decided when attempting to |
| * define 3-dimensional rotations. The following list contains some of the |
| * primary rotation conventions for this package. All method parameters, return |
| * values, and operations follow these conventions unless explicitly stated otherwise. |
| * |
| * <ul> |
| * <li><strong>Active</strong> -- All rotations are "active", meaning that |
| * they transform the vector or point they are applied to instead of transforming the |
| * coordinate system. An active rotation can be converted to a passive one and vice |
| * versa simply by taking the inverse. See |
| * <a href="https://en.wikipedia.org/wiki/Active_and_passive_transformation">here</a> for more details. |
| * </li> |
| * <li><strong>Right-handed</strong> -- All rotation directions follow the |
| * <a href="https://en.wikipedia.org/wiki/Right-hand_rule">right hand rule</a>. |
| * This means that the direction of rotation for a given axis and angle is the same |
| * direction that one's fingers curl if the thumb is pointed along the axis of rotation. |
| * </li> |
| * <li><strong>Radians</strong> -- All angles are in radians. |
| * </li> |
| * </ul> |
