Plane

Remarks

D is the *negated* distance from the origin along the normal, which is the form that makes DotCoordinate a single dot product and is why every clipping and culling routine stores it this way.

Fields and properties (2)

• public readonly Vector3 Normal

  The plane's normal. Unit length for the distance methods to mean anything.

• public readonly float D

  The negated distance from the origin along Normal.

Methods (17)

• public Plane(float a, float b, float c, float d)

  Builds a plane from its four coefficients.

• public Plane(Vector3 normal, float d)

  Builds a plane from a normal and a distance.

• public static Plane FromPointNormal(Vector3 point, Vector3 normal)

  The plane through facing .

• public static Plane FromPoints(Vector3 a, Vector3 b, Vector3 c)

  The plane through three points, wound counter-clockwise when seen from the front.

• public static Plane Normalize(Plane plane)

  Rescales the plane so its normal is unit length.

• public float DotCoordinate(Vector3 point)

  The signed distance from to the plane: positive in front, negative behind, zero on it. Only a distance if the normal is unit length.

• public float DotNormal(Vector3 direction)

  The dot product of the plane's normal with a direction, ignoring D.

• public PlaneIntersectionType Classify(Vector3 point)

  Which side of the plane a point is on.

• public static Plane Transform(Plane plane, in Matrix4x4 matrix)

  Moves a plane by a transform.

• public static bool NearEqual(Plane left, Plane right, float tolerance = 1E-06)

  Whether two planes agree to within a tolerance.

• public static bool operator ==(Plane left, Plane right)

  Exact equality, IEEE semantics. See NearEqual.

• public static bool operator !=(Plane left, Plane right)

  The negation of op_Equality.

• public bool Equals(Plane other)

  Indicates whether the current object is equal to another object of the same type.

• public override bool Equals(object? obj)

  Indicates whether this instance and a specified object are equal.

• public override int GetHashCode()

  Returns the hash code for this instance.

• public override string ToString()

  Returns the fully qualified type name of this instance.

• public string ToString(string? format, IFormatProvider? formatProvider)

  Formats the value of the current instance using the specified format.
