patchb - sets current basis matrices

As shipped in IRIX 6.5.7. Unchanged since IRIX 6.5.

NAME
     patchb - sets current basis matrices

FORTRAN 77 SPECIFICATION
     subroutine patchb(uid, vid)
     integer*4 uid, vid

PARAMETERS
     uid   expects the basis that defines how the control points determine the
           shape of the patch in the "u" direction.

     vid   expects the basis that defines how the control points determine the
           shape of the patch in the "v" direction.

DESCRIPTION
     patchb sets the current basis matrices (defined by defbas) for the u and
     v parametric directions of a surface patch.  patch uses the current u and
     v bases when it executes.
