    4  #!Robjfuzz Object fuzz #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Object fuzz #!EF is 
    5 a method of resolving conflicts between objects at the same distance 
    6 from the camera. For example, it may be desirable to define 
    7 a set of lines coincident with a plane. Normally it will 
    8 be unclear which object is to be displayed in front. In 
    9 addition, single-pixel lines are inherently inaccurate (i.e. they deviate from the 
   10 actual geometric line) by as much as one-half pixel; when displayed 
   11 against a sloping surface, this  #!F-adobe-times-medium-i-normal--18*   x #!EF or  #!F-adobe-times-medium-i-normal--18*   y 
   12 #!EF inaccuracy is equivalent to a  #!F-adobe-times-medium-i-normal--18*   z #!EF inaccuracy related 
   13 to the slope of the surface. The "fuzz" attribute specifies a 
   14  #!F-adobe-times-medium-i-normal--18*   z #!EF value that will be added to the object 
   15 before it is compared with other objects in the scene, thus 
   16 resolving this problem. The fuzz value is specified in pixels. For 
   17 example, a fuzz value of one pixel can compensate for the 
   18 described half-pixel inaccuracy when the line is displayed against a surface 
   19 with a slope of two. #!N #!N #!T,1,161,321,646  #!F-adobe-times-bold-r-normal--18*   #!N TAB
