How practical would it be to include LIDAR in the initial real-world environmental scan to get (or at least seed/constrain with real data samples) an even better collision mesh?

XGrid Portal camera has Lidar, and this scan is made with it as I remember

This tech reminds me of that Source Code(2011) movie for some reason.

some game mode in Cyberpunk 2077 too

Oh yea.. I remember that now...

Mission "The Information" based on a tech named "Braindance".. Thanks for reminding me of this.. was a crazy experience the first time I played.

This also now reminds me of Total Recall(2012) movie, especially that "Rekall" scene.

Plays decently smooth on my M4 Max. It's probably still a long way from being a production-ready replacement for meshed environments, but I could imagine a hybrid mode where certain elements like grass and shrubbery are drawn with gaussians, perhaps with support for basic procedural animation. Great work with the playable demo!

It runs kinda well on the best computer in the world, yeah? :) I have another data point: my ten year old ThinkPad. I get about 10 FPS. Lowering the quality doesn't seem to increase performance. But I am amazed by what I am seeing, and amazed it runs at all! I think it won't be long before the whole world is mapped, and "playable".

> I think it won't be long before the whole world is mapped, and "playable".

People already don't want to use VR, why would they get into/allow scanning with even less immediate value?

I agree with the sprit though, I just think rendering the world is gonna happen from a few generations of iteration on world modeling tech like World Labs/Marble.

Earlier quoted context omitted.

Doesn't give much information about how they were generated

The example they gave of 4d splats used a room with dozens of cameras, and it only talked about the software used for 3d, not 4d.

For the outdoors examples on that site I can only assume they used dozens of drones?

"Back in the day" people were afraid that pupils would create CS (beta 6.5) maps of their schools. Gaussian Splatting would have been very convenient for that :-)

you would need a professional artist, several days and professional expensive equipment. It's not an easy task.

Wouldn't be the first time that having nothing better to do (being in school) and dedication lead to amazing results.

Playing in brave on my Moto g power 2024 was low fps, but as soon as i pressed the shoot button my whole screen went purple pixel distortion lines and I had to restart my phone.

lowest settings? i just approached mobile devices, it's a lot of data and running in a browser .. it's a miracle it works there in the current state (on my 6-years old iPhone it allows me to walk and shoot at least). Streaming LOD is tweakable tbh, it may need to lower settings for mobiles.

yeah, in 2020 when Cyberpunk was out, it was a sci-fi concept!
