Not sure what you are asking. DAZ is an asset and rendering program. Genesis 8 is one of the model versions available for it. DAZ is a free program, but most of the assets must be purchased. You then load your asset models, add any clothing, skins, poses, background, and render this to get an image.
Most of the assets you see here are loaded to the base Genesis 8 models to change the looks, and you can then adjust further with sliders and morphs to get what you are looking for.
I don't think it is like VaM though it might be basically similar.
