Struct SurfSample

pub struct SurfSample {
    pub position: [f32; 3],
    pub normal: [f32; 3],
    pub face_index: usize,
}

Surface sample returned from surface distributions

Fields

position: [f32; 3]

Generated point on the model surface

normal: [f32; 3]

Normalized normal vector of the triangle the point resides in.

OBS: The normal will be pointing out of the positively oriented side of the triangle. As an example, the triangle defined by the verticies [a, b, c] where a = [0.0, 0.0, 0.0], b = [1.0, 0.0, 0.0] and c = [0.0, 1.0, 0.0] has the normal [0.0, 0.0, 1.0]``. While a triangle defined by [b, a, c]has the normal[0.0, 0.0, -1.0]`.

face_index: usize

Index of the triangle the point resides in, in the face slice used for initialization

Trait Implementations

impl Clone for SurfSample

fn clone(&self) -> SurfSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurfSample

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

Formats the value using the given formatter.

impl Distribution<SurfSample> for MeshSurface

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> SurfSample

Samples the model surface uniformly, returning an instance of the SurfSample struct

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl PartialEq for SurfSample

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

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

const 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 SurfSample

fn partial_cmp(&self, other: &SurfSample) -> 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.
