Expand description
Instant-NGP multi-resolution hash grid encoding.
L levels, T buckets per level, F features per entry.
Resolution at level l: N_l = floor(N_min * b^l) where b = exp(ln(N_max/N_min)/(L-1)).
Hash: h(x1,x2,x3) = (x1 XOR x2*pi2 XOR x3*pi3) % T
with pi1=1, pi2=2654435761, pi3=805459861.
