Module volume_render 

Volume rendering equations for NeRF.

Standard NeRF volume rendering:

• alpha_i = 1 - exp(-max(0, sigma_i) * delta_i)
• T_i = exp(-sum_{j<i} sigma_j * delta_j) = prod_{j<i}(1 - alpha_j)
• C(r) = sum_i T_i * alpha_i * c_i
• D(r) = sum_i T_i * alpha_i * t_i
• O(r) = sum_i T_i * alpha_i = 1 - T_N
