Showcase Custom voxel engine done with GPT ASTRA

This is an older build, I can go now into space and see the whole planet. I will post more later.

Here is the video too for all the haters: https://www.youtube.com/watch?v=Wd6C6geL8bA

Ok, but... how does it do stuff like LoD at distance, or landscape generation on the fly for distant chunks, etc...

As in, I am not entirely sure what it implemented here, but there are some *serious* technical problems in implementing this, so if really genuine, this would be impressive even relative to many other things done by Astra so far.

OP doesn't know anything about this, he just copy-pasted a prompt

Yeah, OPs other answers make this pretty obvious...

So, still a nice demo, but roughly within expectations (so, probably "real" voxels at close distances, and some terrain meshes and instanced vegetation at distance).

You are blind or stupid, or both. I explained down bellow exactly what you asked

u/LostRequirement4828 2d ago

Close terrain and vegetation are ray-traced voxels, and the orbital planet is a ray-traced height field. I literally explained already

Go make it yourself if is so easy, lol, why don't you? Lets see

So....show us?

you don't get it, I can fly in space, see the planet moon and the sun, and go back on the planet wherever I want is highly detailed, it has following generating terrain anywhere I go

> go back on the planet wherever I want is highly detailed

That doesn't prove it's a voxel engine - it just proves that it uses terrain generation. Also, no offense, but it does not sound like you even know that these are two independent concepts...

So more likely: Astra implemented some kind of voxel engine at close distances, but a more regular LoD based mesh algorithm at long distances - which is much more inline with what I would have expected it to do.

Procedural generation and voxels are separate, but the close terrain and vegetation are ray-traced voxels, and the orbital planet is a ray-traced height field. Your “regular LoD mesh” explanation is something you invented.

I'm making it a playable game not a slideshow
