Struct rustracer::ray::Ray

pub struct Ray {
    pub origin: Point,
    pub dir: Vector,
    pub tmin: f32,
    pub tmax: f32,
    pub depth: u32,
}

Light Ray struct.

Fields

origin: Point

Origin Point of the light ray.

dir: Vector

Vector propagation direction.

tmin: f32

Minimum time of propagation.

tmax: f32

Maximum time of propagation.

depth: u32

Counts the number of reflection occurred.
If a ray is produced by a reflection, its depth is increased by 1 with respect to the original ray.

Implementations

impl Ray

pub fn at(self, t: f32) -> Point

Return the position of the Ray at time t. The time is measured in units of dir vector’s length.

Trait Implementations

impl Clone for Ray

fn clone(&self) -> Ray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ray

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

Formats the value using the given formatter.

impl Default for Ray

fn default() -> Self

Return as default ray a Ray with:

• the origin of axis as origin
• an x-axis oriented unit vector as dir
• tmin = 1e-5
• tmax = f32::INFINITY
• depth = 0

impl IsClose for Ray

fn is_close(&self, other: Self) -> bool

Return true if all the members of two Ray are close

impl Mul<Ray> for Transformation

type Output = Ray

The resulting type after applying the * operator.

fn mul(self, ray: Ray) -> Self::Output

Performs the * operation.
