ARRUBIU: The Red Giant - Protohistoric Exploration Game

First person game : Explore one of the greatest protohistoric megalithic monuments in the Western Europe, Sardinia (Italy)

Highly accurate 3D reconstruction based on integrated techniques: terrestrial and UAV photogrammetry, laser scanning and archaeological consulting.
- Survey area: 8 hectares
- Topographic GPS survey (Georeferencing): 20 points.
- Laserscanner survey: 100 scans
- Photogrammetric survey: 6000 digital shots
- Model reconstruction: 30.600 Stones



Standard rendering pipeline project.

Looks great. What technique did you use to align the laserscans with photogrammetry?

 

Hey Kreshi,
We took the coordinates of some points spread over the whole relief area with a topographic GPS and then used to georeference laser scans and photogrammetry.

 

So you used ground control points to align both point clouds, merged them together and then reconstructed them as one right? Did you use metashape or reality capture? May i also ask how long the project took from capturing to the final visualization?

 

Yes, more or less this is as you described.
After that we got an high detailed mesh used to overlap the "new" more game friendly stones to the old ones and then replace them all.
Actually there is no direct derivation from surveys in the Unity project.
We added 30.600 stones to cove all reconstruction (internal and external)
1 year project. (2 days survey on site)

Edit:
Yes, Metashape to perform photogrammetry

Photogrammetric model for mobile visualization.

 

I see. So you are creating game ready models out of your data. In case you don't sell the models but sell the visualizations as custom apps, I highly recommend you check out ocean maps. We can stream high resolution reconstruction at ocean maps and do support metashape tiled models out of the box. The laserscan data could be imported into metashape, merged with the photogrammetry dataset and be reconstructed as a tiled model. This approach has pros and cons. The pros are basically automated workflows, you could finalize such visualization apps in under a month. The cons are your apps are big because of the huge amount of (texture) data. While it's not Nanite, it's the closest you can get on Unity for photogrammetry/laserscan datasets at the moment . Anyway, you did a super great job there, so if you release the optimized models on the asset store instead, let me know .

 

I'll check it out for sure...thanks!

 

Looks very cool.
Is bakery better than the build-in system?

 

Hey, thanks!
In my test Bakery is the best. Faster and more advanced than unity GPU lightmapper.

 

mmm i see...

 

Looks really really great. Graphics are awesome. What render pipeline are you using and what's the specs of the PC used? Adding some text next to the video explaining the progress would be great as well I guess . Keep up the good work, you are doing a great job here.

 

Hey Kreshi,
thank you. I appreciate it.

Some specs:
- Unity 2020.3
- Standard Rendering pipeline
- Unity Post Processing except for AO (Horizon Based Ambient Occlusion by Michaël Jimenez ... my favorite)
- Unity Occlusion culling
- Light-map: Bakery by Mr F
- Environment models/textures: Dynamic nature by NatureManufacture
- Fog: Atmospheric Height Fog by BOXOPHOBIC
- Special Materials (tri-planar) for the whole structure: Better Lit by JasonBooth.

Interactive installation specs (4k 60fps):
- CPU: I7-11700K
- RTX3060TI
- 32Gb ram
- 65" 4K Ultra HD Monitor TV

 

Are you using Enviro for the godrays?
That's insane graphics and performance you are getting out of the build-in render pipeline! The build-in pipeline is definitely underrated given the great results you have achieved here .

 

It wasn't easy to optimize the whole scene to get a solid frame rate, but one of the first things was to use a static skybox.
I captured the dynamic skybox (old uSky asset ), far terrain and mountains from a separated scene.
So the fog does a good job of hiding the transition between the static skybox and the nearby ground.
All this allows me to keep the far clipping plane of the camera as low as possible(in my case 700).
Goodrays come from SC Post Effects Pack from Staggart Creations... very performant and integrated with post processing v2.
You're right ... the standard pipeline can still give so much because of thousands of excellent assets from the store.
