Constructors
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
-
clone(
) → Curve -
Creates a clone of this instance.
inherited
-
computeFrenetFrames(
int segments, bool closed) → FrenetFrames -
Generates the Frenet Frames. Requires a curve definition in 3D space. Used
in geometries like
TubeGeometry
orExtrudeGeometry
.inherited -
copy(
Curve source) → Curve -
Copies another
name
object to this instance.inherited -
fromJson(
Map< String, dynamic> json) → Curve -
Copies the data from the given JSON object to this instance.
inherited
-
getLength(
) → double -
Get total curve arc length
inherited
-
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 range0, 1
.inherited -
getPoints(
[int divisions = 5]) → List< Vector?> -
divisions -- number of pieces to divide the curve into. Default is
5
.inherited -
getSpacedPoints(
[int divisions = 5, int offset = 0]) → List< Vector?> -
divisions -- number of pieces to divide the curve into. Default is
5
.inherited -
getTangent(
double t, [Vector? optionalTarget]) → Vector -
t
- A position on the curve. Must be in the range0, 1
.inherited -
getTangentAt(
double u, [Vector? optionalTarget]) → Vector -
u
- A position on the curve according to the arc length. Must be in the range0, 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.
inherited
-
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.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
