The so called “Maximum Intensity Projektion” determines for each viewing ray the maximum of the occuring emissions (not observable in reality).

Using Ray-Casting:

Sampling the volume along each viewing ray r(s) parametrized by the viewing distance s.
For each sampling step: $I'=max(V(r(s)),I)$.

Using View Aligned Slices:

Simulate the MIP by rendering each slice with maximum blend function:
$RGB_{frame}' = max(RGB_{fragment},RGB_{frame})$

Note: MIP is order independent.
