NAME

patchprecision − sets the 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: longint);

DESCRIPTION

patchprecision sets the precision at which curves defining a wire frame patch are drawn.  The u and v directions for a patch specify the precisions independently.  Patch precisions are similar to curve precisions−they specify the minimum number of line segments used to draw a patch. The actual number of line segments 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 ensures the intersection of patch curves.
