      a component of the plane

    • b: number

      b component of the plane

    • c: number

      c component of the plane

    • d: number

      d component of the plane

    Returns Plane

Properties

d

Find examples in Playground
d: number

d component of the plane

normal

normal: Vector3

Normal of the plane (a,b,c)

Methods

asArray

Find examples in Playground
  • asArray(): number[]
  • Returns number[]

    the plane coordinates as a new array of 4 elements [a, b, c, d].

clone

Find examples in Playground
  • Returns Plane

    a new plane copied from the current Plane.

copyFromPoints

Find examples in Playground
  • Updates the current Plane from the plane defined by the three given points.

    Parameters

    Returns Plane

    the updated Plane.

dotCoordinate

Find examples in Playground
  • Calcualtte the dot product between the point and the plane normal

    Parameters

    Returns number

    the dot product (float) of the point coordinates and the plane normal.

getClassName

Find examples in Playground
  • getClassName(): string
  • Returns string

    the string "Plane".

getHashCode

Find examples in Playground
  • getHashCode(): number
  • Returns number

    the Plane hash code.

isFrontFacingTo

Find examples in Playground
  • Checks if the plane is facing a given direction

    Parameters

    • direction: DeepImmutable<Vector3>

      the direction to check if the plane is facing

    • epsilon: number

      value the dot product is compared against (returns true if dot <= epsilon)

    Returns boolean

    True is the vector "direction" is the same side than the plane normal.

normalize

Find examples in Playground
  • Normalize the current Plane in place.

    Returns Plane

    the updated Plane.

signedDistanceTo

Find examples in Playground
  • Calculates the distance to a point

    Parameters

    Returns number

    the signed distance (float) from the given point to the Plane.

transform

Find examples in Playground
  • Applies a transformation the plane and returns the result

    Parameters

    Returns Plane

    a new Plane as the result of the transformation of the current Plane by the given matrix.

Static FromArray

Find examples in Playground
  • Creates a plane from an array

    Parameters

    • array: DeepImmutable<ArrayLike<number>>

      the array to create a plane from

    Returns Plane

    a new Plane from the given array.

Static FromPoints

Find examples in Playground

Static FromPositionAndNormal

Find examples in Playground
  • Creates a plane from an origin point and a normal

    Parameters

    Returns Plane

    a new Plane the normal vector to this plane at the given origin point. Note : the vector "normal" is updated because normalized.

Static SignedDistanceToPlaneFromPositionAndNormal

Find examples in Playground
  • Calculates the distance from a plane and a point

    Parameters

    Returns number

    the signed distance between the plane defined by the normal vector at the "origin"" point and the given other point.
