patchprecision(3)  —  Silicon Graphics Beta Release

NAME

patchprecision - sets precision at which curves are drawn

SPECIFICATION

C
patchprecision(usegments, vsegments)
long usegments, vsegments;

FORTRAN
subroutine patchp(usegments, vsegments)
integer*4 usegments, vsegments

Pascal
procedure patchprecision(usegments, vsegments: long);

DESCRIPTION

patchprecision sets the precision at which curves defining a wire frame patch are drawn.  Precisions are specified independently in the u and v directions for a patch. Patch precisions are similar to curve precisions − they specify the minimum number of line segments used in drawing a patch. The actual number of line segments used in the display of a patch is an even multiple of the number of curves used in drawing the patch greater than the specified precision. This multiple is used in order to guarantee the intersection of patch curves.
