#!CSeaGreen #!N  #!Rglopt Rendering Options... #!N #!EC #!N #!N You can 
choose between software and hardware rendering if you are running Data 
Explorer on a workstation with a graphics card that supports hardware 
rendering. Approximations in both types of rendering help the user to 
see the effect of rotation, roam, or navigation interactions before rendering 
and display are complete. #!N #!N To set the rendering options, 
select  #!F-adobe-times-bold-r-normal--18*   Rendering Options... #!EF in the  #!F-adobe-times-bold-r-normal--18*   Options #!EF pull-down 
menu in the Image window. This causes the  #!F-adobe-times-bold-r-normal--18*   Rendering... #!EF 
dialog box to appear, as illustrated in  #!Lrend62,dxall327 f Figure 62  #!EL  . #!Cbrown #!N

the manual. #!N Figure 62. Rendering Options Dialog Box #!EF #!N 
#!EC #!N #!N The  #!F-adobe-times-bold-r-normal--18*   Rendering... #!EF dialog box allows you 
to select the rendering mode with a toggle button. If you 
select  #!F-adobe-times-bold-r-normal--18*   hardware #!EF , this means "use hardware if available" 
at the time Data Explorer is run. If a graphics card 
which supports hardware rendering is not available, software rendering will be 
used instead. #!N #!N You can specify the approximation method that 
Data Explorer uses for each of two execution states--button-up execution and 
button-down execution. Button-down execution is applicable in execute-on-change mode and in 
navigation. #!N #!N For example, you might specify  #!F-adobe-times-bold-r-normal--18*   None #!EF 
for the approximation method for button-up execution, and  #!F-adobe-times-bold-r-normal--18*   Dots #!EF 
for the approximation method for button-down execution. When holding the mouse 
button down in  #!F-adobe-times-bold-r-normal--18*   Rotate #!EF mode (with  #!F-adobe-times-bold-r-normal--18*   Execute on 
Change #!EF enabled), these rendering methods display a dot representation of 
the object, giving you quick feedback on your camera position, until 
you release the mouse button, at which point the object is 
rendered normally. The following is a brief description of the rendering 
methods you can specify with this dialog box. For detailed information 
about the rendering options, see  #!Ldisplay,dxall807 h Display  #!EL  in IBM Visualization Data Explorer

#!I50 #!N No approximation method is specified, so a complete rendering 
of the image is done. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Wireframe  #!F-adobe-times-medium-r-normal--18*   
(available only with hardware rendering) #!EF #!EF #!I50 #!N Renders the 
object as a wireframe, at the specified density. Surfaces are rendered 
as wireframe meshes, while points and volumes are rendered as dots. 
Wireframes are produced at full or fractional density. #!N #!I0 #!N 
 #!F-adobe-times-bold-r-normal--18*   Dots #!EF #!I50 #!N For hardware rendering, this approximation renders 
all points, surfaces, and volumes as dots, at the specified density. 
Lines are rendered as wireframe. Dots are produced at full or 
fractional density. #!N #!N For software rendering, all points, surfaces, and 
volumes are rendered as dots. You cannot specify the density for 
software rendering. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Box #!EF #!I50 #!N Draws 
the bounding box of each field in the object to be 
rendered. #!I0 #!N #!N #!N #!N While the Dots or Wireframe 
hardware rendering approximation methods are specified, the integer for  #!F-adobe-times-bold-r-normal--18*   Render 
every #!EF controls the density of the rendering approximation. For the 
Dots approximation, it means that every  #!F-adobe-times-medium-i-normal--18*   n #!EF th vertex 
is rendered, where  #!F-adobe-times-medium-i-normal--18*   n #!EF is the integer specified. For 
Wireframe approximation, the rendering depends on the type of connections. For 
example, if the connections are triangles, it means that every  #!F-adobe-times-medium-i-normal--18*   
n #!EF th triangle is rendered. You can use the  #!F-adobe-times-bold-r-normal--18*   
Render every #!EF value to control the speed of your rendering; 
the higher the value, the faster an object can be rendered. 
The default value is 1 (meaning every dot and every wireframe 
is rendered). #!N #!N The  #!F-adobe-times-bold-r-normal--18*   Render every #!EF box is 
grayed out during software rendering, and during hardware rendering that is 
not Dots or Wireframe approximations. Note: Do not use the Options 
module to set hardware-rendering options if you intend to use the 
 #!F-adobe-times-bold-r-normal--18*   Rendering... #!EF dialog box: options set by the Options module 
are overridden by those set through the dialog box (see  #!Ldisplay,dxall807 h Display  #!EL
