Struct PcgRng 

pub struct PcgRng { /* private fields */ }

PCG-XSH-RR random number generator (O’Neill, 2014)

Provides deterministic, high-quality random numbers with minimal state.

Implementations

impl PcgRng

pub fn new(seed: u64) -> Self

Create new RNG with seed

pub fn next_u32(&mut self) -> u32

Generate next 32-bit random value

pub fn next_f32(&mut self) -> f32

Generate random float in [0, 1)

pub fn hash_pixel(seed: u32, index: u32, frame: u32) -> u32

Generate hash for pixel index (pure function for GPU)

pub fn should_fill(seed: u32, index: u32, frame: u32, probability: f32) -> bool

Check if pixel should be filled based on probability
