Struct NormalCone 

pub struct NormalCone { /* private fields */ }

A direction and an angular reach about it.

The axis is stored normalised, so the stored value does not depend on the length the caller passed.

Implementations

impl NormalCone

pub fn new(axis: Vec3, half_angle: f64) -> Result<Self, FaceSelectionError>

A cone about axis reaching half_angle radians.

Errors

FaceSelectionError::InvalidAxis when axis is not finite or has no direction; FaceSelectionError::InvalidHalfAngle when half_angle is not finite or outside [0, pi].

pub fn axis(self) -> Vec3

The unit axis.

pub fn half_angle(self) -> f64

The half-angle in radians.
