- void curvebasis
- (short id)
Set the basis matrix for a curve to the matrix referenced by
id. The matrix and it's id are tied together with a call to defbasis.
- void curveprecision
- (short nsegs)
Define the number of line segments used to draw a
curve.
- void rcrv
- (Coord geom
[4][4])
Draw a rational curve.
- void rcrvn
- (long n,Coord geom
[][4])
Draw n - 3 rational curve segments. Note: n must be at
least 4.
- void crv
- (geom
[4][3])
Draw a curve.
- void crvn
- (long n,Coord geom
[][3])
Draw n - 3 curve segments. Note: n must be at least 4.
- void curveit
- (short n)
Draw a curve segment by iterating the top matrix in the
matrix stack as a forward difference matrix. This performs
n iterations.
