#!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.
