Emission Plus Absorption

For the optical model of emission and absorption we use alpha-blending instead of the maximum blend function. Here the emission is the RGB part of the fragment colors and the absorption is equivalent to the opacity A of the fragment colors.

Emission alone (order independent):
DVR1

Absorption alone (order independent):
DVR2

Emission plus absorption (order dependent):
DVR3

Compared to MIP (order independent):
DVR4
