Did we watch the same movie? They got bunch of physics stuff right, like the water planet, the relative aging due to being near the massive black hole etc. Only thing that wasn't "correct" was the wormhole and especially the tesseract, but that was some creative writing which allowed for a nice twist. I enjoyed it, a nice scifi.

It was completely uneven. Cooper sobbing as he listened to years of messages from his family? I wish I could've written that. The twist where Mann activated his beacon because he didn't want to die alone? Solid. We need the gravity equation to get off Earth because the crops are dying? Love can escape a black hole through the tesseract? This is just patent technobabble nonsense. Where _Interstellar_ fails is in expos…

Plus it helps that Fifth Element has that scene... where the General "would like to take a few pictures... for the archives"!

It is a pity they didn't spend comparable effort on the story. I thought it was a really disappointing film, especially after they banged on so much about how good the physics in it was (apart from the black hole rendering, it wasn't).

Incredible soundtrack, though.

Also the robots were cool.

Implemented using semi-realistic Einstein equations. They do talk about implementing a fully realistic version in the paper, but the director deemed it visually too confusing for the audience, so you only get to see a dumbed-down version in the movie.

Is there a visualization of the fully realistic version available somewhere?

Yes, there is

I worked on this movie, I was at DNEG at the time. One of the standout things that I remember is that this particular simulation was toxic to the fileserver that it was being stored on. From what I recall, I don't think that it was running on that many machines at once. Mainly because it required the high memory nodes that were expensive. I think it was only running on ~10 possibly 50 machines concurrently. But I cou…

The paper mentions that the accretion disc was rendered in Houdini.

It also mentions that ‘several hundred’ of their 1633 10-core, 156GB (weird number?) blade servers were used, but didn’t seem to go into details on data storage.

Is it possible you were working at the compositing phase, which would have been very heavy on random read and writes, resulting in more wear on the disks?

Interstellar blackhole VFX implemented in 40k lines of C++ Would be a better title

It's clickbait, but I'm amused since it implies the blackhole is the main star of the movie.

Is it not? Would you say the Sun was the main star then?

It can still make some sense, if you think that the future life forms expressed their inherited love to fix things way back in time.

100% agree, like you I was hyped after the pre-release teaser PR stuff came out about the realistic black hole rendering etc, was hoping for an actually decent sci-fi and then just a lame story culminating in "space ghosts" for me, arguably most disappointing movie ever

Don't watch 'Ad Astra' then. That's also incredibly disappointing (IMHO).

Their starship was bullshit. On earth they needed a big Saturn 5 like rocket to bring it into space and later they fly into orbit like it's nothing. If the planets they visited had much lower gravity then earth this may be possible, but this wasn't noticeable or talked about. And even on Mars you need much more fuel to get into orbit than could be stored in their tiny ship.

Well, if you look for this, many if not most movies will have some inaccuracy or holes in explanation like this. In the end, I watch movies for entertainment. If I'm looking for scientific precision, I see a documentary instead.

We're talking about a movie in which a space agency builds an enormous rocket entirely in secret and without any suppliers; then enrolls the astronaut at the head of the mission on the same day of the departure; and finally launches the rocket from inside its office halls. ¯\_(ツ)_/¯ https://www.youtube.com/watch?v=x9xFRch7N5o

Well, if the launch fails, they won't need the office anymore. If the launch succeeds, same.
