I remember going to a planetarium at the local university while in school some 15 years ago. They told us how they use Stellarium to create the skies and Celestia (https://celestiaproject.space/) to create scripted tours for their exhibits. Both were compatible with the hemispherical projector they used.

As soon as I went home I downloaded them both and spent hours visiting stars in Celestia and exploring the sky in Stellarium. It’s great to see they are still quite active.


I have also tried one and I had a similar experience but only in some scenarios. It might be a different effect to what you had but I’ll try to explain.

In my experience I got a good 3D effect for objects that were right in the center but the moment things got close to the edge the illusion broke. At times it did look a bit like 3D content on a 2D screen.

Objects near the edge of the retroreflective area disappear when you would normally expect them to appear ‘above’ the mat. They somewhat get around this by presenting most information below the surface. Apps like board games were the worst for it because they typically use the whole mat and they typically appear on or above the surface. Anything above the surface just gets cut off around the edge. The larger board that can be tilted up at the back helped but only from one angle.


They did, the README was updated 4 days ago with a banner explaining the situation.


Typically the AI to detect the AI is exactly what they use to train networks like Deep Fake in the first place. GANs are effectively just a local arms race between two machine learning networks.


It is certainly a little bold of Bridenstine to comment on other space companies being behind schedule given NASA’s own delays.


Elon Musk said 5% of SpaceX was working on Starship and that the hardware for crew would be ready this year (in interview to CNN after the QA he said October for in flight abort and November for DM-2).


I think that 5% claim is dubious.

Almost certainly the top minds at spacex are focussed on starship, and the 5% number might only be kinda-true because starship is being built with a lot of contractors.


Well when you tell a customer you will have all hands on deck and then are out back playing with your go-kart then expect your billion dollar customer will say something.


I imagine all the necessary hands are already on deck for Crew Dragon.

Starship wasn’t built by the Falcon or Crew Dragon manufacturing teams, and the vast majority of the design and engineering currently happening for Starship has long been completed for Crew Dragon.

Let’s also remember that NASA is hardly the only company that pays SpaceX, they have other income sources and what they do with that income is ultimately their choice. Unless they are using NASA money to build Starship there should be no problem.


From this[1] article:

"Musk said in 2018 that SpaceX was “all hands on deck for Crew Dragon,” and it would be making trips to the ISS by December 2018.

After that, he said, “most of our engineering resources will be dedicated to BFR, and I think that will make things go quite quickly,” he said. BFR was the earlier name for Starship."

"All hands on deck" is not some subjective term, it is naval and means get everyone on deck now to repel boarders.

Except there is nothing they can do now. There are a ton of safety reviews which depend on NASA, and only a small amount of people at SpaceX are required to keep the NASA team more than filled with work.

Elon responded saying he would do whatever it took to go faster, but there was nothing he could do.


He said, today, that 5% of SpaceX was working on Starship.


Both statements can be true, depending on which portion of space x is engineers and how Elon uses the word resources here


This is missing the particularly annoying 'halts for 5 seconds then catches up' option.


Not parent commenter but they may mean this: Bula (Fijian greeting) [1] The same article also mentions Aloha being trademarked followed by cease and desists being sent restaurants in Hawaii using the word.

There are plenty of others but these are some that have stood out to me.

SIGGRAPH has a VR Theatre where they show short VR films [1].

EyeJack is a platform for AR art, though you may need to visit an exhibit to see the actual art. [2]

The renders aren't that bad, but that is a terrible choice for the cutout image given the lighting angle with thin shadows.


Good question, and you are probably correct, not worth the effort. There was one launch where they broadcast the drone ship landing from a nearby support ship (or helicopter, I don't remember exactly) which was cool to see but I haven't seem them do it since.
