Struct PathState 

pub struct PathState {
    pub ray: Ray,
    pub throughput: [f64; 3],
    pub radiance: [f64; 3],
    pub depth: u32,
    pub max_depth: u32,
}

Path tracer state for a single sample path.

Fields

ray: Ray

Current ray.

throughput: [f64; 3]

Accumulated throughput (product of BRDFs).

radiance: [f64; 3]

Accumulated radiance.

depth: u32

Current bounce depth.

max_depth: u32

Maximum bounce depth.

Implementations

impl PathState

pub fn new(ray: Ray, max_depth: u32) -> Self

Create a new path state.

pub fn should_continue(&self) -> bool

Returns true if path tracing should continue.

pub fn russian_roulette(&mut self, survival_prob: f64) -> bool

Apply Russian roulette termination. Returns false if path is terminated.
