CurvePath class - curve_path library

Constructors

CurvePath()
CurvePath.fromJson(Map<String, dynamic> json)

Properties

arcLengthDivisions ↔ int: This value determines the amount of divisions when calculating the cumulative segment lengths of a curve via getLengths. To ensure precision when using methods like getSpacedPoints, it is recommended to increase arcLengthDivisions if the curve is very large. Default is 200.

Methods

add(Curve curve) → void
clone() → Curve: Creates a clone of this instance.
inherited
closePath() → void: Adds a lineCurve to close the path.
computeFrenetFrames(int segments, bool closed) → FrenetFrames: Generates the Frenet Frames. Requires a curve definition in 3D space. Used in geometries like TubeGeometry or ExtrudeGeometry.
inherited
copy(Curve source) → CurvePath: Copies another name object to this instance.
override
fromJson(Map<String, dynamic> json) → CurvePath: Copies the data from the given JSON object to this instance.
override
getCurveLengths() → List<double>
getLength() → double: Get total curve arc length
override
getLengths(int? divisions) → List<double>: Get list of cumulative segment lengths
inherited
getPoint(double t, [Vector? optionalTarget]) → Vector?: override
getPointAt(double u, [Vector? optionalTarget]) → Vector?: u - A position on the curve according to the arc length. Must be in the range 0, 1 .
inherited
getPoints([int divisions = 12]) → List<Vector?>: divisions -- number of pieces to divide the curve into. Default is 12.
override
getSpacedPoints([num divisions = 40, num offset = 0.0]) → List<Vector?>: divisions -- number of pieces to divide the curve into. Default is 5.
override
getTangent(double t, [Vector? optionalTarget]) → Vector: t - A position on the curve. Must be in the range 0, 1 .
inherited
getTangentAt(double u, [Vector? optionalTarget]) → Vector: u - A position on the curve according to the arc length. Must be in the range 0, 1 .
inherited
getUtoTmapping(double u, [double? distance]) → double: Given u in the range ( 0 .. 1 ), returns t also in the range ( 0 .. 1 ). u and t can then be used to give you points which are equidistant from the ends of the curve, using getPoint.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>: Returns a JSON object representation of this instance.
override
toString() → String: A string representation of this object.
inherited
updateArcLengths() → void: Update the cumulative segment distance cache. The method must be called every time curve parameters are changed. If an updated curve is part of a composed curve like CurvePath, updateArcLengths must be called on the composed curve, too.
override

Operators

operator ==(Object other) → bool: The equality operator.
