Trait implemented by point types usable by ncollide.

Associated Types

type Vector: Vector + Add<Self::Vector> + Sub<Self::Vector> + Mul<Self::Real> + Div<Self::Real> + Neg + AddAssign<Self::Vector> + SubAssign<Self::Vector> + MulAssign<Self::Real> + DivAssign<Self::Real>

The underlying vector type used to express points coordinates.

Required Methods

fn axpy(&mut self, a: Self::Real, rhs: &Self, b: Self::Real)

Computes self = a * rhs + b * self.

fn ccw_face_normal(pts: &[&Self]) -> Option<Unit<Self::Vector>>

Computes the outward normal of a 2D or 3D face.

In 2D, returns a unit vector orthogonal to the oriented segment formed by { pts[0], pts[1] }. This vector points toward the half-space "on the right" of this segment. In 3D, returns the unit normal of the triangle formed by { pts[0], pts[1], pts[2] } and oriented counter-clock-wise.
