Draws a rational cubic spline curve.
void rcrv(Coord geom)
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.|
