Draws a rational cubic spline curve.
FORTRAN (libfgl.a)
void rcrv(Coord geom[4][4])
SUBROUTINE RCRV(geom) REAL geom(4,4)
The rcrv subroutine draws a rational cubic spline curve segment using the current curve basis and precision.
The geom parameter specifies the four control points of the curve segment.
| geom | Specifies an array containing the four control points of the curve segment. |
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. |
