Struct PathTracerBuffer 

pub struct PathTracerBuffer {
    pub width: usize,
    pub height: usize,
    pub accumulator: Vec<[f32; 3]>,
    pub sample_count: Vec<u32>,
}

A pixel accumulation buffer for progressive rendering.

Fields

width: usize

Buffer width in pixels.

height: usize

Buffer height in pixels.

accumulator: Vec<[f32; 3]>

Accumulated colour per pixel (RGB, floating point).

sample_count: Vec<u32>

Number of samples accumulated per pixel.

Implementations

impl PathTracerBuffer

pub fn new(width: usize, height: usize) -> Self

Create a new buffer of width × height pixels, all zeroed.

pub fn add_sample(&mut self, x: usize, y: usize, color: [f32; 3])

Add a colour sample to pixel (x, y).

pub fn get_pixel(&self, x: usize, y: usize) -> [f32; 3]

Get the averaged colour at pixel (x, y).

pub fn to_rgb8(&self) -> Vec<u8>

Return a gamma-corrected (gamma=2) u8 RGB image row-major.

pub fn clear(&mut self)

Reset all accumulated samples.

pub fn total_samples(&self) -> u64

Total number of samples accumulated across all pixels.
