Struct collision::Plane

pub struct Plane<S> {
    pub n: Vector3<S>,
    pub d: S,
}

A 3-dimensional plane formed from the equation: A*x + B*y + C*z - D = 0.

Fields

• n: a unit vector representing the normal of the plane where:
  • n.x: corresponds to A in the plane equation
  • n.y: corresponds to B in the plane equation
  • n.z: corresponds to C in the plane equation
• d: the distance value, corresponding to D in the plane equation

Notes

The A*x + B*y + C*z - D = 0 form is preferred over the other common alternative, A*x + B*y + C*z + D = 0, because it tends to avoid superfluous negations (see Real Time Collision Detection, p. 55).

Fields

n: Vector3<S>

Plane normal

d: S

Plane distance value

Methods
