Enum FaceSide

pub enum FaceSide {
    Front,
    Back,
    Coplanar,
}

Which side of a triangle the ray arrived from.

Determined by the certified orientation of the ray origin against the triangle plane, not by the sign of a floating-point dot product, so a grazing ray does not flip sides on rounding.

Variants

Front

The origin lies on the positive side of the triangle’s winding normal.

Back

The origin lies on the negative side of the triangle’s winding normal.

Coplanar

The origin lies exactly in the triangle’s plane.

Trait Implementations

impl Clone for FaceSide

fn clone(&self) -> FaceSide

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FaceSide

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FaceSide

fn eq(&self, other: &FaceSide) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
