panda3d.core.NurbsCurveInterface¶

from panda3d.core import NurbsCurveInterface

class NurbsCurveInterface¶

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.

appendCv(v: LVecBase3) → int¶

appendCv(v: LVecBase4) → int

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

static getClassType() → TypeHandle¶

Return type: TypeHandle

getCv(n: int) → LVecBase4¶

Return type: LVecBase4

getCvPoint(n: int) → LVecBase3¶

Returns the position of the indicated CV.

Return type: LVecBase3

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¶

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) → None¶

writeCv(out: ostream, n: int) → None¶
