4Navigating in a Scene #!N #!EC #!N #!N You can move
5your camera within the scene in all directions using the  #!F-adobe-times-bold-r-normal--18*
6Navigate #!EF mode. As well as being able to change your
7view direction like the other modes,  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF also lets
8you move  #!F-adobe-times-medium-i-normal--18*   through #!EF an object and view it from
9the inside out. #!N #!N When you use  #!F-adobe-times-medium-i-normal--18*   Navigate #!EF
10mode, the camera is automatically changed to perspective rendering. #!N #!N
11You can also move your camera in one direction while looking
12in another direction. For instance, you can move forward past the
13left side of an object while looking to the right, enabling
14you to see the object as you move past it. #!N
15#!N Unlike the  #!F-adobe-times-bold-r-normal--18*   Roam #!EF and  #!F-adobe-times-bold-r-normal--18*   Rotate #!EF modes,
16which appear to adjust the object to change your view, or
17the  #!F-adobe-times-bold-r-normal--18*   Zoom #!EF mode, which appears to adjust the camera
18lens to change your view, the  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode appears
19to actually move your camera around the scene, while the objects
20you are viewing remain stationary. Note: Because Data Explorer does not
21support perspective rendering of volumes, you cannot navigate software-rendered volumes. #!N
22#!N To move your camera within the scene: #!N #!I0 #!N
23 #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. Select the  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF
24mode from the  #!F-adobe-times-bold-r-normal--18*   Mode #!EF option box. This adds some
25controls, illustrated in  #!Lvc357,dxall309 f Figure 57  #!EL  , to the  #!F-adobe-times-bold-r-normal--18*   View Control... #!EF
26dialog box. #!N #!I30 #!N 2. The mouse buttons control the
27navigate motion of the camera, while the setting of the  #!F-adobe-times-bold-r-normal--18*
28Look #!EF option box controls the direction the camera is pointing.
29The  #!F-adobe-times-bold-r-normal--18*   Look #!EF options are illustrated in  #!Llookopt5,dxall309 t Table 5  #!EL  . Note:
30You can also enable  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode by using the
31 #!F-adobe-times-bold-r-normal--18*   intrctnMode #!EF parameter to the Image tool (see Image in
32IBM Visualization Data Explorer User's Reference). #!N #!N With  #!F-adobe-times-bold-r-normal--18*   Look
33#!EF set to  #!F-adobe-times-bold-r-normal--18*   Forward #!EF , you have more control
34over the trajectory the camera moves along in the scene. To
35move forward, click on the left mouse button. To move backward,
36click on the right mouse button. The position of the mouse
37pointer on the image indicates the angle at which you travel;
38that is, the point where the mouse pointer is located moves
39more towards the center of the image area. #!Cbrown #!N  #!F-adobe-times-medium-r-normal--18*

51mouse pointer in the image area. #!N #!N With the exception
52of  #!F-adobe-times-bold-r-normal--18*   Align #!EF , all of the options in the
53 #!F-adobe-times-bold-r-normal--18*   Look #!EF option box affect only the direction the camera
54is pointing.  #!F-adobe-times-bold-r-normal--18*   Align #!EF adjusts the current navigate direction (the
55forward direction) to be the same as the current  #!F-adobe-times-bold-r-normal--18*   Look
56#!EF value. For example, if the camera is pointing 45deg to
57the right of the current navigate direction,  #!F-adobe-times-bold-r-normal--18*   Align #!EF changes
58the navigate direction to be 45deg to the right of its
59current value, thereby aligning travel direction with camera direction. #!N Note:
60Switching to another mode (such as  #!F-adobe-times-bold-r-normal--18*   Rotate #!EF ) from
61 #!F-adobe-times-bold-r-normal--18*   Navigate #!EF while the Look value is something other than
62Forward, automatically aligns the navigate direction with the camera direction. #!N
63#!N #!N If the camera is pointing in any direction but
64forward, you can still use the left and right mouse buttons
65to move forward and backward; the trajectory of your movement is
66the same as it was when you last traveled forward. In
67this case, the center mouse button has no effect. #!N #!I30
68#!N 3. The  #!F-adobe-times-bold-r-normal--18*   Navigate #!EF mode uses two values to
69control its precision. These are controlled by the two sliders on
70the  #!F-adobe-times-bold-r-normal--18*   View Control... #!EF dialog box. They are: #!N #!I0
71#!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Motion #!EF #!I50 #!N Controls the
72speed of execution as you move the camera forward and backward.
73The higher the number, the faster the speed, and the faster
74your camera appears to move. In addition to using the slider,
75you can use the up- and down-arrow keys to adjust this
76value (be sure the cursor is in the Image window). #!N
77#!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Pivot #!EF #!I50 #!N Controls the increment of
78the turn angle when you turn using the center mouse button.
79The higher the number, the more drastic the turn. In addition
80to using the slider, you can use the left- and right-arrow
81keys to adjust this value (be sure the cursor is in
82the Image window). #!I0 #!N #!N #!N #!I0 #!N #!EF #!N
