curvebasis(3G)curvebasis(3G)NAMEcurvebasis - 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.)
DESCRIPTIONcurvebasis 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.
