Struct TangentSpace 

pub struct TangentSpace { /* private fields */ }

Wraps the relevant results generated when calculating the tangent space for a particular vertex on a particular face.

Typically, you will call tangent to retrieve the tangent value.

Implementations

impl TangentSpace

pub const fn tangent(&self) -> [f32; 3]

Returns the normalized tangent as an [x, y, z] array.

pub const fn bi_tangent(&self) -> [f32; 3]

Returns the normalized bi-tangent as an [x, y, z] array.

pub const fn tangent_magnitude(&self) -> f32

Returns the magnitude of the tangent.

pub const fn bi_tangent_magnitude(&self) -> f32

Returns the magnitude of the bi-tangent.

pub const fn is_orientation_preserving(&self) -> bool

Indicates if this generated tangent preserves the original orientation of the face.

pub const fn tangent_encoded(&self) -> [f32; 4]

Returns an encoded summary of the tangent and bi-tangent as an [x, y, z, w] array.

Trait Implementations

impl Clone for TangentSpace

fn clone(&self) -> TangentSpace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for TangentSpace

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TangentSpace

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