Quaternions - how to limit axis? I get the quaternion from axis and angle<br> var angle = Math.acos( _rotateStart.dot( _rotateEnd ) / _rotateStart.length() / _rotateEnd.length() );<br>
var axis = ( new THREE.Vector3() ).cross( _rotateStart, _rotateEnd ).normalize();<br>
quaternion.setFromAxisAngle( axis, -angle );<br>
<br>
Quat angle is perpendicular to the camera's lookat and view is still rolling, when I try to set axis perpendicular to lookat alghoritm crashes.<br>
Thank's for link, now I better understand trackball concept, but still I don't know how to solve my problem with rolling. Please write more. |

Quaternions - how to limit axis? It's simply to make it when key is pressed, but problem is how to do it with mouse controller. |
