curvebasis(3G)

NAME
     curvebasis - selects a basis matrix used to draw curves

C SPECIFICATION
     void curvebasis(basid)
     short basid;

PARAMETERS
     basid   expects the basis identifier of the basis matrix you want to use
             when drawing a curve. (You must have previously called defbasis
             to assign a basis identifier to a basis matrix.)

DESCRIPTION
     curvebasis selects a basis matrix (by its basis identifier) as the
     current basis matrix to draw curve segments.  The basis matrix determines
     how the system uses the control points when drawing a curve.  Depending
     on the basis matrix, the system draws bezier curves, cardinal spline
     curves, b-spline curves and others. The system does not restrict you to a
     limited set of basis matrices. You can define basis matrices to match
     whatever constraints you want to place on the curve.
