Sets the number of curves used to represent a patch.
FORTRAN (libfgl.a)
void patchcurves(Int32 ucurves, Int32 vcurves)
SUBROUTINE PATCHC(ucurves, vcurves) INTEGER*4 ucurves, vcurves
The patchcurves subroutine sets the number of u and v curves that represents a patch as a wire frame.
| ucurves | Specifies the number of curve segments to be drawn in the u direction. |
| vcurves | Specifies the number of curve segments to be drawn in the v direction. |
The example C language program patch1.c uses the patchcurves subroutine to define to the patch subroutine the number of curves to use in drawing three surface patches.
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
| /usr/include/gl/gl.h | Contains C language constant and variable type definitions for GL. |
| /usr/include/gl/fgl.h | Contains FORTRAN constant and variable type definitions for GL. |
