Volume Density to Opacity VOP node

Computes the opacity of a uniform volume given a density.

This VOP converts volume density to opacity by evaluating Beer’s law.

Tip

You should connect dPdz in the surface context to the distance parameter.

Parameters

Signature

Controls whether to evaluate monochrome or rgb opacity.

Density
