Constructors
constructor
A Curve3 object is a logical object, so not a mesh, to handle curves in the 3D geometric space. A Curve3 is designed from a series of successive Vector3. Tuto : https://doc.babylonjs.com/features/featuresDeepDive/mesh/drawCurves#curve3-object
Parameters
points: Vector3[]
points which make up the curve
Returns Curve3
Methods
continueSearch playground for continue
Returns a new instance of Curve3 object : var curve = curveA.continue(curveB); This new Curve3 is built by translating and sticking the curveB at the end of the curveA. curveA and curveB keep unchanged.
Parameters
curve: DeepImmutableObject<Curve3>
the curve to continue from this curve
Returns Curve3
the newly constructed curve
get
Returns Vector3[]
the Curve3 stored array of successive Vector3
lengthSearch playground for length
Returns number
the computed length (float) of the curve.
Static Arc
Returns a Curve3 object along an arc through three vector3 points: The three points should not be colinear. When they are the Curve3 is empty.
Parameters
first: Vector3
(Vector3) the first point the arc must pass through.
second: Vector3
(Vector3) the second point the arc must pass through.
third: Vector3
(Vector3) the third point the arc must pass through.
Optional steps: number
(number) the larger the number of steps the more detailed the arc.
Optional closed: boolean
(boolean) optional with default false, when true forms the chord from the first and third point
Optional fullCircle: boolean
Circle (boolean) optional with default false, when true forms the complete circle through the three points
Returns Curve3
the created Curve3
Static Create
Returns a Curve3 object along a CatmullRom Spline curve :
Parameters
points: DeepImmutableArray<Vector3>
(array of Vector3) the points the spline must pass through. At least, four points required
nbPoints: number
(integer) the wanted number of points between each curve control points
Optional closed: boolean
(boolean) optional with default false, when true forms a closed loop from the points
Returns Curve3
the created Curve3
