Enum SurfaceFacing

pub enum SurfaceFacing {
    AgainstNormal,
    WithNormal,
}

Orientation of a surface crossing relative to the field’s local z axis.

This is a geometric fact about winding, not a claim that a facet is a floor, a ceiling, or anything walkable. NOT-A-VERDICT

Variants

AgainstNormal

The triangle normal opposes the sampling direction (an entering crossing).

WithNormal

The triangle normal agrees with the sampling direction (an exiting crossing).

Trait Implementations

impl Clone for SurfaceFacing

fn clone(&self) -> SurfaceFacing

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SurfaceFacing

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

Formats the value using the given formatter.

impl Hash for SurfaceFacing

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SurfaceFacing

fn cmp(&self, other: &SurfaceFacing) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SurfaceFacing

fn eq(&self, other: &SurfaceFacing) -> 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.

impl PartialOrd for SurfaceFacing

fn partial_cmp(&self, other: &SurfaceFacing) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
