Navigating in a Scene #!N #!EC #!N #!N You can move 
your camera within the scene in all directions using the  #!F-adobe-times-bold-r-normal--18*   
Navigate #!EF mode. As well as being able to change your 
view direction like the other modes,  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF also lets 
you move  #!F-adobe-times-medium-i-normal--18*   through #!EF an object and view it from 
the inside out. #!N #!N When you use  #!F-adobe-times-medium-i-normal--18*   Navigate #!EF 
mode, the camera is automatically changed to perspective rendering. #!N #!N 
You can also move your camera in one direction while looking 
in another direction. For instance, you can move forward past the 
left side of an object while looking to the right, enabling 
you to see the object as you move past it. #!N 
#!N Unlike the  #!F-adobe-times-bold-r-normal--18*   Roam #!EF and  #!F-adobe-times-bold-r-normal--18*   Rotate #!EF modes, 
which appear to adjust the object to change your view, or 
the  #!F-adobe-times-bold-r-normal--18*   Zoom #!EF mode, which appears to adjust the camera 
lens to change your view, the  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode appears 
to actually move your camera around the scene, while the objects 
you are viewing remain stationary. Note: Because Data Explorer does not 
support perspective rendering of volumes, you cannot navigate software-rendered volumes. #!N 
#!N To move your camera within the scene: #!N #!I0 #!N 
 #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. Select the  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF 
mode from the  #!F-adobe-times-bold-r-normal--18*   Mode #!EF option box. This adds some 
controls, illustrated in  #!Lvc357,dxall309 f Figure 57  #!EL  , to the  #!F-adobe-times-bold-r-normal--18*   View Control... #!EF 
dialog box. #!N #!I30 #!N 2. The mouse buttons control the 
navigate motion of the camera, while the setting of the  #!F-adobe-times-bold-r-normal--18*   
Look #!EF option box controls the direction the camera is pointing. 
The  #!F-adobe-times-bold-r-normal--18*   Look #!EF options are illustrated in  #!Llookopt5,dxall309 t Table 5  #!EL  . Note: 
You can also enable  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode by using the 
 #!F-adobe-times-bold-r-normal--18*   intrctnMode #!EF parameter to the Image tool (see Image in 
IBM Visualization Data Explorer User's Reference). #!N #!N With  #!F-adobe-times-bold-r-normal--18*   Look 
#!EF set to  #!F-adobe-times-bold-r-normal--18*   Forward #!EF , you have more control 
over the trajectory the camera moves along in the scene. To 
move forward, click on the left mouse button. To move backward, 
click on the right mouse button. The position of the mouse 
pointer on the image indicates the angle at which you travel; 
that is, the point where the mouse pointer is located moves 
more towards the center of the image area. #!Cbrown #!N  #!F-adobe-times-medium-r-normal--18*

TAB Align #!N #!T,0 #!N #!N #!N #!N If the camera 
is pointing forward, you can use the center mouse button to 
change your direction. Clicking on the center mouse button adjusts your 
direction (and view of the object) toward the position of the 
mouse pointer in the image area. #!N #!N With the exception 
of  #!F-adobe-times-bold-r-normal--18*   Align #!EF , all of the options in the 
 #!F-adobe-times-bold-r-normal--18*   Look #!EF option box affect only the direction the camera 
is pointing.  #!F-adobe-times-bold-r-normal--18*   Align #!EF adjusts the current navigate direction (the 
forward direction) to be the same as the current  #!F-adobe-times-bold-r-normal--18*   Look 
#!EF value. For example, if the camera is pointing 45deg to 
the right of the current navigate direction,  #!F-adobe-times-bold-r-normal--18*   Align #!EF changes 
the navigate direction to be 45deg to the right of its 
current value, thereby aligning travel direction with camera direction. #!N Note: 
Switching to another mode (such as  #!F-adobe-times-bold-r-normal--18*   Rotate #!EF ) from 
 #!F-adobe-times-bold-r-normal--18*   Navigate #!EF while the Look value is something other than 
Forward, automatically aligns the navigate direction with the camera direction. #!N 
#!N #!N If the camera is pointing in any direction but 
forward, you can still use the left and right mouse buttons 
to move forward and backward; the trajectory of your movement is 
the same as it was when you last traveled forward. In 
this case, the center mouse button has no effect. #!N #!I30 
#!N 3. The  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode uses two values to 
control its precision. These are controlled by the two sliders on 
the  #!F-adobe-times-bold-r-normal--18*   View Control... #!EF dialog box. They are: #!N #!I0 
#!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Motion #!EF #!I50 #!N Controls the 
speed of execution as you move the camera forward and backward. 
The higher the number, the faster the speed, and the faster 
your camera appears to move. In addition to using the slider, 
you can use the up- and down-arrow keys to adjust this 
value (be sure the cursor is in the Image window). #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Pivot #!EF #!I50 #!N Controls the increment of 
the turn angle when you turn using the center mouse button. 
The higher the number, the more drastic the turn. In addition 
to using the slider, you can use the left- and right-arrow 
keys to adjust this value (be sure the cursor is in 
the Image window). #!I0 #!N #!N #!N #!I0 #!N #!EF #!N
