Please spend more time gathering and sharing lossless 3D measurements so people can learn statistics, models and visualization

You mostly ignored “how to capture real volumetric 3D flows at nanometer scale”. There are 3D capture methods that can “see” at cm scale, at mm scale, at microMeter scale. I traced groups who work at femtometer scale and smaller. If the raw data from these groups is shared in lossless form, then there is “captured reality” in digital form for people (an AIs) to try their hand at painting with simple brushes.

Making pretty pictures is a skill. My sister is an artist and I have watched her paint. It teaches me nothing, except she has patience and has honed her skill over many decades. You are not teaching people how to create visualizations, unless they already know mathematics and computing. You are not teaching how to use tools that can make “canned” visualizations for certain 3D volumetric problems, so not likely they can afford the tools you use, nor your methods that depend on your skills, not the skills of the computer. Yes, you give lots of examples and lessons from what you observed playing with your visualization tools.

You miss an essential point. Where does the raw data for what actually happens in fluids comes from? NOT from “big” fluid simulators. But from measurements on real fluids. Now your tools are like paints and brushes to an artist. You are probably too young to remember polka dot paint from cartoons. With real data, you can get as much as you can, as fine detail as you can, look for patterns, try to “paint” those with your visualization tools, match them mathematically to “calibrate” your submodels, then see if you can combine many fine detailed models of special events into a statistically valid whole region visualization. The wavelets started out that way. The orthogonal representations started that way. The multipole and Fourier methods stated out that way. But soon each of those “painters” forgot they learned from reality, then we are just watching someone else paint. Someone else transcribe reality with what tools we can afford.

What you are doing it not wrong. But it has no goal, other than “you too can make pretty pictures if you spend time learning things I learned and work for years perfecting your skill.
