NurbsCurveInterface

from panda3d.core import NurbsCurveInterface

class NurbsCurveInterface

Bases:

This abstract class defines the interface only for a Nurbs-style curve, with knots and coordinates in homogeneous space.

The NurbsCurve class inherits both from this and from ParametricCurve.

Inheritance diagram

appendCv(v: LVecBase3) → int

appendCv(v: LVecBase4) → int

appendCv(x: float, y: float, z: float) → int

static getClassType() → TypeHandle

getCv(n: int) → LVecBase4

getCvPoint(n: int) → LVecBase3: Returns the position of the indicated CV.

getCvWeight(n: int) → float: Returns the weight of the indicated CV.

getCvs() → list

getKnot(n: int) → float

getKnots() → list

getNumCvs() → int

getNumKnots() → int

getOrder() → int

insertCv(t: float) → bool

removeAllCvs()

removeCv(n: int) → bool

setCv(n: int, v: LVecBase4) → bool

setCvPoint(n: int, v: LVecBase3) → bool: Repositions the indicated CV. Returns true if successful, false otherwise.

setCvPoint(n: int, x: float, y: float, z: float) → bool: Repositions the indicated CV. Returns true if successful, false otherwise.

setCvWeight(n: int, w: float) → bool: Sets the weight of the indicated CV without affecting its position in 3-d space.

setKnot(n: int, t: float) → bool

setOrder(order: int)

writeCv(out: ostream, n: int)
