#!F-adobe-helvetica-medium-r-normal--18* #!N #!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 #!F-adobe-times-medium-r-normal--18* #!Rrend62 #!N #!N Graphics omitted from Online Documentation. Please see 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 User's Reference. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* None #!EF #!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 in IBM Visualization Data Explorer User's Reference. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Limdep,dxall328 h Image Depth #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
