patchbasis(3G)

NAME
     patchbasis - sets current basis matrices

C SPECIFICATION
     void patchbasis(uid, vid)
     long 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
     patchbasis sets the current basis matrices (defined by defbasis) for the
     u and v parametric directions of a surface patch.  patch uses the current
     u and v bases when it executes.
