Heavy stuff, will attempt to read when I'm not so tired.
Radiator hose went on the S-10 today, brought be back to reality in a hurry.

The topic these people are exploring is very interesting.

It looks like those guys are having fun.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model the flow of air around the object by having a computer solve a complex set of equations—a procedure that usually takes hours, or even an entire day. Nobuyuki Umetani from Autodesk research (now at the University of Tokyo) and Bernd Bickel from the Institute of Science and Technology Austria (IST Austria) have now significantly sped up this process, making streamlines and parameters available in real time. Their method, which is the first to use machine learning to model flow around continuously editable 3-D objects, will be presented at this year's prestigious SIGGRAPH conference in Vancouver, where IST Austria researchers are involved in a total of five presentations.....................
The researchers also proved in their study that the machine learning method achieves an impressive accuracy, a prerequisite for engineering. Nobuyuki Umetani explains: "When simulations are made in the classical way, the results for each tested shape are eventually thrown away after the computation. This means that every new computation starts from scratch. With machine learning, we make use of the data from previous calculations, and if we repeat a calculation, the accuracy increases."

That is cool. And the AI does this without killing all the humans with poisonous gasses. Even better.

Let the battle of the generative adversarial AIs begin!
They should be using OpenVDB for their 'wind tunnel'.
Quote:
OpenVDB is an open source C++ software library comprising a novel hierarchical data structure and a large suite of tools for the efficient storage and manipulation of sparse volumetric data discretized on three-dimensional grids. It is developed and maintained by DreamWorks Animation for use in volumetric applications typically encountered in feature film production. The library was primarily developed by Ken Museth, Peter Cucka, Mihai Aldén and David Hill.
....
It has Python support.
Adopted by Houdini, RenderMan, Arnold, RealFlow, Maxwell Render, Modo, V-Ray, Octane Render, and 3Delight.

This aligns with my dream of being able to find a 50/50 morph between the Volkhart-Saggita V2 and a Corvette Stingray.
