NAME

shaderange − sets range of color indices used in depth-cueing

SPECIFICATION

C
shaderange(lowindex, highindex, z1, z2)
Colorindex lowindex, highindex;
Screencoord z1, z2;

FORTRAN
subroutine shader(lowindex, highindex, z1, z2)
integer*2 lowindex, highindex, z1, z2

Pascal
procedure shaderange(lowindex, highindex: longint;
z1, z2: longint);

DESCRIPTION

shaderange sets the range of color indices used in drawing depth-cued lines and points.  The range [z1, z2] is mapped linearly into the color index range.  z values less than z1 map to highindex; z values greater than z2 map to lowindex.
