Yep, unreal is surprisingly efficient on the graphics side of things, but it also wants 70-something GB just to install and that's before it starts setting up the graphics cache which adds another 40 GB iirc.

1TB SSDs are $90.

HN is rich and detached from reality in other parts of the world. People still have to manage their savings to buy storage in non rich world.

VR capable computers are quite cheap. Cheaper than a low spec apple macbook pro running m1. For 2-3k you can get a beast of a machine running everything on real high settings.

Considring a brand new top of the line Nvidia GPU will currently cost you almost 2k, your prices feel a little ~4-5 years ago.

In my experience you can almost always do much better buying a full computer on a good sale than buying components and building it yourself.

No, AI will generate the 3d scene just by looking at the 2d footage. It can fill in the blanks (i.e. provide textures for areas that are invisible in the film).

It will make a chuffing good effort but fail hilariously in >99% of cases but then people will parade the fraction that make sense.

It's getting better all the time, check https://www.youtube.com/watch?v=_Y1-KlTEmwk

I think it will be commonplace to virtually walk around in movie scenes turned into 3d scenery by AI by the end of next year. I can see this turning into a real industry. Who wouldn't like to wander, fly and swim around Pandora, the world of Avatar? It will also lead to questions about the copyright of the resulting models, probably somewhat dependant on how automated this process is.

The Trek community created a pretty detailed model of the Enterprise-D, but took it down due to copyright concerns. It's still floating around if you know where to look but it's a real shame that development on it had to stop out of legal fears, well founded or not.

How much is the rest of a VR setup?

I think it's worth taking a step back and just marveling at what's now possible to do with an off-the-shelf software. Yeah, it's "just" 50 fps, but ... would you just look at it! 4 years ago there was an equally fascinating "Paris apartment" VR demo, but the movement was limited and the amount of work that went into appears to have been orders of magnitude more - https://www.benoitdereau.com/ Go back 10 years and see…

Off the shelf yes, but wow…. The requirements for Unreal are unreal. Recent versions handle real-time global illumination (Lumen) and dynamically render geometry to insane levels of detail (nanite). Both of these are groundbreaking achievements. But having had to install this in a bunch of university computers I can tell you that it comes at a cost. Interestingly, the most significant issue is the space these install…

> The requirements for Unreal are unreal.

This has been true since 1998.

Wait, disk space was the limiting factor, not GPUs?

Yep. The install size of unreal is a known issue: https://m.youtube.com/watch?v=n7vwGnKSbmE&feature=youtu.be

Our lab computors have 500gb of space. Each time a new profile is activated by a student, that eats up around 5 to 10 gig. In addition… Video editing eats up storage space like there is no tomorrow (the Cache requirements of Resolve are another issue). Nanite supports scene with very dance meshes (downloaded directly from Unreals online store). These add up quickly in terms of file size, especially as each comes in several versions, with multiple levels of detail.

Ideally we would have liked to install more than one version of Unreal. Unreal updates regularly and files created with each version cannot be guaranteed to be opened by subsequent versions. However, this was one saving we made.

There are sample files which are actually very instructive but which we did not install.

All of these issues compounded and towards the end of sem we were having a tough time.
