#!EC #!N #!N These tools create a displayable image from a 
renderable object or modify the visual characteristics of the object(s) being 
displayed. For example, Normals and FaceNormals could be used to add 
shading to a geometrical structure created with RubberSheet (Realization category), while 
Light and AmbientLight could be used to change its default lighting. 
#!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lambligh,dxall766 h AmbientLight  #!EL  #!EF #!I50 #!N 
Produces an ambient light. You can specify the color of the 
light. Ambient lights illuminate a surface equally, regardless of direction, so 
an object illuminated only with ambient light is not shaded. Note 
that it is not necessary to specify an ambient light, because 
a small amount of ambient light is built into the object 
model. However, explicitly specified lighting overrides the default lighting. #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!Larrange,dxall768 h Arrange  #!EL  #!EF #!I50 #!N Creates a single image from 
a collection of images. You can specify how many images to 
put in a row. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lautocam,dxall771 h AutoCamera  #!EL  #!EF #!I50 
#!N This module produces an appropriate camera as input to the 
Render or Display module. Specifying a "look-from" direction changes this default 
camera. The width of the image in model units (orthographic projection) 
or the field of view (perspective projection), or the image size 
and aspect ratio can also be changed. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
 #!Lcamera,dxall780 h Camera  #!EL  #!EF #!I50 #!N Produces a camera for input to the 
Render or Display module. You can specify the "look-to" point, the 
"look-from" point, the width of the image in units corresponding to 
those in the data, the image size, and the aspect ratio. 
Camera differs from AutoCamera in that it specifies a "look from" 
a  #!F-adobe-times-medium-i-normal--18*   point #!EF instead of a  #!F-adobe-times-medium-i-normal--18*   direction #!EF . 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lclipbox,dxall786 h ClipBox  #!EL  #!EF #!I50 #!N Clips an object 
using a box. You can specify the box explicitly, as the 
two corners defining a box, or it can be the bounding 
box of an object. The module renders only that part of 
the object inside the box. The Render, Display, or Image tool 
actually performs the clipping. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lclippla,dxall787 h ClipPlane  #!EL  #!EF #!I50 
#!N Clips an object by a plane. The user specifies the 
plane with a point and a normal. The side of the 
plane the normal projects into is the side that will be 
clipped (i.e., not displayed). The Render, Display, or Image tool performs 
the clipping. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Ldisplay,dxall807 h Display  #!EL  #!EF #!I50 #!N Renders 
and/or displays an image to the screen. If a camera is 
not provided, the Display module expects the first input to be 
an image (e.g., the output of Render or Arrange). #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!Lfacenor,dxall847 h FaceNormals  #!EL  #!EF #!I50 #!N Computes normals on a surface. 
When you use the FaceNormals module, each face of the surface 
is flat-shaded. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Limage,dxall860 h Image  #!EL  #!EF #!I50 #!N This 
tool renders and displays an image to the screen. It performs 
like the AutoCamera and Display modules combined. Using the Image tool 
to render an image enables many direct interactors that are not 
available when using AutoCamera and Display. These options are available in 
the  #!F-adobe-times-bold-r-normal--18*   View Control #!EF option of the  #!F-adobe-times-bold-r-normal--18*   Options #!EF 
pull-down menu in the Image window. For example, see  #!Lchav,dxall300 h Controlling the Image: View Control...  #!EL  in 
IBM Visualization Data Explorer User's Guide. The Image tool is available 
only in the graphical user interface. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Llight,dxall884 h Light  #!EL  
#!EF #!I50 #!N Produces a distant point light. You can specify 
the direction and color of the light. Note that it is 
not necessary to specify a light, because there is a default 
light built into the object model; however, explicitly specified lighting overrides 
the default lighting. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lnormals,dxall897 h Normals  #!EL  #!EF #!I50 #!N 
Computes point or face normals for shading a surface. For example, 
you can use this module to produce shading on rubbersheets and 
boundaries. However, shading on an isosurface is smoother if you use 
the gradient shading options built into the Isosurface module. #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!Loverlay,dxall900 h Overlay  #!EL  #!EF #!I50 #!N Overlays two images. The result 
is a new image that can be displayed using the Display 
module. The new image is a pixel-by-pixel sum of the two 
images, where 1 -  #!F-adobe-times-bold-r-normal--18*   blend #!EF attenuates the base-image pixels, 
and  #!F-adobe-times-bold-r-normal--18*   blend #!EF attenuates the overlay-image pixels, (  #!F-adobe-times-bold-r-normal--18*   blend 
#!EF is a value between 0 and 1). You can also 
perform chromakeying by specifying  #!F-adobe-times-bold-r-normal--18*   blend #!EF as an RGB color 
or as a string specifying a color. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
 #!Lrender,dxall923 h Render  #!EL  #!EF #!I50 #!N Renders an object and creates an image. 
The object can be any combination of volumes, surfaces, lines, and 
points, and you can clip the object. You need to provide 
a camera to the Render module to specify the viewing direction. 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lreorent,dxall924 h Reorient  #!EL  #!EF #!I50 #!N Rotates or inverts 
an image or a group of images. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
 #!Lrotate,dxall928 h Rotate  #!EL  #!EF #!I50 #!N Rotates an object around specified axes. The 
Render, Display, or Image tool actually performs the rotation. #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!Lscale,dxall934 h Scale  #!EL  #!EF #!I50 #!N Changes an object's dimensions along 
the  #!F-adobe-times-medium-i-normal--18*   x #!EF ,  #!F-adobe-times-medium-i-normal--18*   y #!EF , and  #!F-adobe-times-medium-i-normal--18*   
z #!EF axes. The scaling is actually performed in the Render, 
Display, or Image tool. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lscalscr,dxall935 h ScaleScreen  #!EL  #!EF #!I50 
#!N Scales all screen objects (typically captions and color bars) by 
a specified amount. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lshade,dxall942 h Shade  #!EL  #!EF #!I50 #!N 
Allows you to specify object-shading parameters such as specularity. #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*    #!Ltransfo,dxall967 h Transform  #!EL  #!EF #!I50 #!N Moves, rotates, and resizes an 
object. The Render, Display, or Image tool actually performs the translation. 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Ltransla,dxall968 h Translate  #!EL  #!EF #!I50 #!N Moves an object 
along the  #!F-adobe-times-medium-i-normal--18*   x, y #!EF , and  #!F-adobe-times-medium-i-normal--18*   z #!EF 
axes. The Render, Display, or Image tool actually performs the translation. 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lupdatca,dxall973 h UpdateCamera  #!EL  #!EF #!I50 #!N Makes specified alterations 
to the input camera. #!I0 #!N #!N #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*
