Colors define the photometric characteristics of an Object; they may be 
associated with points, triangles, or lights, and may be used to 
define its reflectance or opacity. In Data Explorer, colors are floating-point 
numbers and therefore open ended, as is light intensity in the 
real world. However, real output devices can display only a limited 
range of intensities. In general, the range from 0.0 to 1.0 
is by default mapped onto the range of displayable intensities of 
the output device, so colors should normally be specified in this 
range. Data Explorer provides a routine that constructs an RGB color 
structure. #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N typedef struct rgbcolor { #!N
