shaderange() — Silicon Graphics
NAME
shaderange - sets range of color indices used when depthcueing
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: Colorindex;
z1, z2: Screencoord);
DESCRIPTION
shaderange sets the range of color indices used in drawing depthcued lines and points. Z values in the range specified by z1, z2 are mapped linearly into the range of color indices specified by lowindex, highindex. Z values less than z1 map to lowindex and z values greater than z2 map to highindex.
