ffBlendSrf

Go to: Related nodes. Attributes.

Compute a freeform surface that blends between two surface rails. Each rail may consist of one or more surface curves on one or more surfaces. The tangent direction the blended surface leaves each rail is determined by flipLeft and flipRight.

Long name (short name)	Type	Default	Flags
autoAnchor (aa)	bool	booltrue
If true and both paths are closed, automatically determine the value on the right rail so that they match
autoNormal (an)	bool	booltrue
If true, the direction of each starting tangent is computed based on given geometry.
positionTolerance (pt)	double	double0.1
The positional C(0) tolerance of the blend surface to the adjacent surfaces.
flipLeftNormal (fln)	bool	boolfalse
If true, flip the starting tangent of the left boundary.
flipRightNormal (frn)	bool	boolfalse
If true, flip the starting tangent of the right boundary.
tangentTolerance (tt)	double	double0.1
The tangent G(1) continuity tolerance of the blend surface to the adjacent surfaces.
leftAnchor (la)	double	0.0
The reference parameter on the left boundary where the blend surface starts in the case of the closed rail.
leftCurve (lc)	nurbsCurve	nullptr
The surface curves comprising the left boundary.
leftEnd (le)	double	1.0
The reference parameter on the left boundary where the blend surface ends.
leftRail (lr)	nurbsCurve	nullptr
The left rail boundary.
leftStart (ls)	double	0.0
The reference parameter on the left boundary where the blend surface starts.
multipleKnots (mk)	bool	booltrue
If true, use the new blend which produces fully multiple interior knots
outputSurface (os)	nurbsSurface	nullptr
The computed blend surface.
reverseLeft (rvl)	bool	boolfalse
If true, reverse the direction of the left boundary. autoDirection must be false for this value to be considered.
reverseRight (rvr)	bool	boolfalse
If true, reverse the direction of the right boundary. autoDirection must be false for this value to be considered.
rightAnchor (ra)	double	0.0
The reference parameter on the right boundary where the blend surface starts in the case of the closed rail.
rightCurve (rc)	nurbsCurve	nullptr
The surface curves comprising the right boundary.
rightEnd (re)	double	1.0
The reference parameter on the right boundary where the blend surface ends.
rightRail (rr)	nurbsCurve	nullptr
The right rail boundary.
rightStart (rs)	double	0.0
The reference parameter on the right boundary where the blend surface starts.
