Struct bevy::math::prelude::InfinitePlane3d

pub struct InfinitePlane3d {
    pub normal: Dir3,
}

pub fn new<T>(normal: T) -> InfinitePlane3d

where T: TryInto<Dir3>, <T as TryInto<Dir3>>::Error: Debug,

Create a new InfinitePlane3d from a normal

Panics

pub fn from_points(a: Vec3, b: Vec3, c: Vec3) -> (InfinitePlane3d, Vec3)

Create a new InfinitePlane3d based on three points and compute the geometric center of those points.

The direction of the plane normal is determined by the winding order of the triangular shape formed by the points.

Panics

Panics if a valid normal can not be computed, for example when the points are collinear and lie on the same line.
