Function stratified_sample 

pub fn stratified_sample(
    t_near: f32,
    t_far: f32,
    n_samples: usize,
    rng: &mut LcgRng,
) -> NerfResult<Vec<f32>>

Sample n_samples positions along a ray between t_near and t_far using stratified (jittered) sampling.

t_i = t_near + (i + U(0,1)) / n_samples * (t_far - t_near) for i = 0..n_samples

Errors

Returns InvalidBounds if t_far <= t_near, InvalidSampleCount if n_samples == 0.
