Optical model of a self-emitting gas:

• Gas emits light of a distinct color (neon light)
• Emitted light gets absorbed partly (clouds of smoke)
• Additional ambient background brightness

The scalar value of the volume is interpreted as density of the gas.

Linear relationship between scalar value $s$, density $\rho$ and absorption resp. emission:

• the higher the scalar value, the higher the density
• the higher the density, the higher the absorption
• the higher the density, the higher the emission
• in vacuum emission and absorption is zero
