Description
My latest project... continuing my seemingly never ending quest to fully comprehend the volumetric effects and settings.

I decided that I wanted to have a visual representation of the Scattering vs. Absorption settings so that I could easily compare and comprehend the interactions of the two.

The Scattering and Absorption were broken down to 10% increment values.

This is the same scene, rendered repeatedly, with just the Scattering and Absorption numbers changed. The scene is Stonemason's "The Ministry Prop" which I chose for the simple black and white textures. A single Reality light is positioned up, outside of the prop, shining down at an approximate 45 degree angle. Camera is positioned inside the prop, not within the volumetric cube.

To remain consistent, the lighting was left at "Auto Linear" in Luxrender.

Each scene was then rendered to a consistent 5k sample level.

Not all of the scenes have been rendered yet. I still have about 60 left to go. And, unfortunately, alphabetical order resulted in the most complicated (and least useful) scenes to be rendered first.

However, it did produce enough results to test as a proof of concept. Plus it is making me consider doing a second version of this narrowed down to just the upper left hand corner. It seems like that 25% of the scale would show the most dramatic difference.
