Constructor & Destructor Documentation

__init__()

corc.curve.Curve.__init__	(		self,
		float	tmin,
		float	tmax,
			nsamples = 4096 )

Member Function Documentation

_build_arclength_table()

corc.curve.Curve._build_arclength_table ( self, int nsamples )

protected

derivatives()

corc.curve.Curve.derivatives	(		self,
		float	t )

Return (p, v, a, j) as 3-vectors at parameter t.

p()

np.ndarray corc.curve.Curve.p	(		self,
		float	t )

position()

corc.curve.Curve.position	(		self,
			t )

Return [x, y, z] at parameter t; components are Jets if t is a
Jet. Subclasses implement this with jet-friendly operations.

Reimplemented in corc.curve.Lame, corc.curve.StraightLine, corc.curve.Trefoil, and corc.tests.test_curve_frame._Circle.

s_of_t()

float corc.curve.Curve.s_of_t	(		self,
		float	t )

Arc length from tmin to t (table + local Gauss correction).

speed()

float corc.curve.Curve.speed	(		self,
		float	t )

t_of_s()

float corc.curve.Curve.t_of_s	(		self,
		float	s )

Invert the arc length: Newton on s(t) - s with table start.
