#!F-adobe-helvetica-medium-r-normal--18* #!N #!N #!Rtall17 Controlling Rotation #!N #!N #!N To rotate an object in the Image window, first click on the #!F-adobe-times-bold-r-normal--18* Mode #!EF option box (initially displaying #!F-adobe-times-bold-r-normal--18* None #!EF ) and then select #!F-adobe-times-bold-r-normal--18* Rotate #!EF from the displayed list. #!F-adobe-times-bold-r-normal--18* Rotate #!EF becomes the current mode and a set of axes appears in the lower right-hand corner of the window. You can rotate the object in two dimensions (clockwise and counterclockwise) or in three by rotating the axes. You can also cause the object to rotate "continuously" (i.e., in coordination with the axes). #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* 2-D Rotation #!EF #!I50 #!N Position the mouse cursor in the Image window and hold down the #!F-adobe-times-medium-i-normal--18* right #!EF mouse button: clockwise movement of the mouse produces clockwise rotation of the #!F-adobe-times-medium-i-normal--18* axes #!EF ; counterclockwise movement produces counterclockwise rotation. When the mouse button is released, the #!F-adobe-times-medium-i-normal--18* object #!EF rotates by the same amount as the axes have, assuming the same relative position in the window. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* 3-D Rotation #!EF #!I50 #!N Position the mouse cursor in the Image window and hold down the #!F-adobe-times-medium-i-normal--18* left #!EF mouse button: the mouse now behaves like a track ball and the axes move accordingly. When the mouse button is released, the object rotates by the same amount as the axes have, assuming the same relative position in the window. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* Continuous Rotation #!EF #!I50 #!N Once you have selected #!F-adobe-times-bold-r-normal--18* Rotate #!EF mode, you can make the object rotate along with the axes: select #!F-adobe-times-bold-r-normal--18* Execute #!EF in the menu bar and then #!F-adobe-times-bold-r-normal--18* Execute on Change #!EF in the pull-down menu ( #!F-adobe-times-bold-r-normal--18* Execute #!EF is highlighted). The image is now replaced by a dot representation of the object (see rendering options in IBM Visualization Data Explorer User's Guide). The movement of the mouse (and the axes) is reflected directly and continuously in the movement of this dot version. Note: Movement of the axes is essentially synchronous with movement of the mouse, but the "response time" of the dot version may vary, depending on the machine and configuration. #!I0 #!N #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1.
