Screen Class #!N #!EC #!N #!N A Screen Object is an
Object that maintains a size and alignment with the screen (output
image) independent of the camera view and scaling transformations applied to
it. #!N #!N Three options are provided for the interpretation of
translations applied to a Screen Object. First, a translation applied to
the Screen Object may specify a new position for the origin
of the Screen Object in world space ( #!F-adobe-times-bold-r-normal--18* SCREEN_WORLD #!EF
). Second, a translation applied to the Screen Object may specify
a new location for the Screen Object in the image, measured
in pixels, where (0,0) refers to the lower-left corner of the
image ( #!F-adobe-times-bold-r-normal--18* SCREEN_PIXEL #!EF ). Third, a translation applied to
the Screen Object may specify a new location for the Screen
Object in the image, measured in viewport-relative coordinates, where (0,0) refers
to the lower-left corner of the image and (1,1) refers to
the upper-right corner of the image ( #!F-adobe-times-bold-r-normal--18* SCREEN_VIEWPORT #!EF ).
#!N #!N In addition, with regard to #!F-adobe-times-medium-i-normal--18* z #!EF ,
the object may be displayed either in place in the scene,
in front of all objects, or behind all objects, according to
whether the #!F-adobe-times-bold-r-normal--18* z #!EF parameter to #!F-adobe-times-bold-r-normal--18* DXNewScreen() #!EF is
0, #!F-adobe-times-medium-i-normal--18* +1 #!EF , or #!F-adobe-times-medium-i-normal--18* -1 #!EF respectively. #!CForestGreen
