[Fist Person Exploration] Virtual Archaeology : Ancient Megalithic Walls

Web player ... be patient about 460mb. (remember no Chrome )

Hi there,
I would like to show our new work presented recently also at Museums & Heritage Show in London.
The project consist of a 3d reconstruction of an archaeological site named "Sa Mandra Manna" - Sardinia ITALY.

All the site (except the vegetation) has been modeled by a photogrammetric processing of digital images taken by helicopter, drone and on the ground (about 9000 digital shots).

We have developed a standalone version with classic controls (keyboard and mouse/gamepad) and a touch version to be exposed by a Multi-touch Table on site.
For mobile platform, we have developed a smartphone/tablet version and a VR Cardboard version.

Feel free to leave any comment or feedback

Cheers
Max

Hi.
What image effect have you used? It looks really nice

 

Beautiful !

 

Thanks NatureManufacture,
the post process camera effects used are :
- SMAA
- SSAO pro
- Scion
- Sun shafts

Hedgehog Team ...Thanks Nicolas!

 

This is very beautiful. Excellent visuals, minus one exception. The text on the mustard yellow UI panel is difficult to read.

 

Ridiculously nice looking.

Thak you ... yes you are right but i didn't find a good solution for that.I'll try to improve the reading comfort.

Thanks.

 

Has anyone tested the webplayer.?... yes I know it is so heavy ( you need to wait much) but i would like to see some gameplay feedbacks.

Added in the first post.

 

Gorgeous views.

 

Thank you raven!

 

I noticed a issue in Speedtree and in general all the leaves shaders which are abnormally lit when observed against the light.
Unity 5.3.4p6 deferred + linear.
Anyone have some tips to fix or some version (unity 5.3.5?) which fix the issue?
Some similar issuetracker reports this an this.

Edit:
Seems that a fix is on the way . Here the post

Edit2:
Solved Here

 

Some new captures!

 

That's really well done and atmospheric. However, as someone else pointed out in the scion thread, some additional insects and pollen particle effects might help bring the scene to life a bit more. The other thing I noticed is that the rocks look very flat in a close-up view, which is too bad because they're the main points of interest in the scene. Isn't there a way to get the heightmap from the photogrammetry data or pseudo-bake it from the photos? With it you could either use a tesselation shader or tesselate and displace the mesh for the rocks in your 3D app. I think that this could improve the visuals in this scene even more.

 

Hi christoph_r,
thanks for your feedback.



The site is big for a photogrammetry process (2 Hectar explorable) and the project had as target device a multi-touch table kiosk which as you know usually do not have a game ready hardware. I did a compromise between technical and aesthetic with in mind the hardware limits.


Some numbers:

Walls meshes:
- 2M tris original photoscanned model
- 200k tris optimized/decimated model (normal map, AO map from 2M model)
- Full unwrapped by tre UV texture spaces and textured by tre 8k diffuse, bump and AO maps.

Nature meshes:
- Grass 300k tris
- Trees 400k tris

Background Areas:
- 1 km2 near terrain with areal photo plus trees and grass
- 150 km2 far terrain with areal photo



The photogrammetric process from digital photos don't give a perfect representation of the small geometry especially if you have a big area to be scanned.
I Did not find a fine way to extract the height map of this complex organic mesh to make some test with tassellation. i'm open to any tips.

WOOOW awesome.
Fa piacere ogni tanto vedere qualche altro italiano qui.
Magnifico lavoro comunque.

 

Thank you Nove0
Grazie!

 

That's why they looked like nuraghes, they are nuraghes! Great work!

 

New Video and screenshots without vegetation rendering issues (LUX Deferred)

 

Veramente bello Bravi!

 

Fantastic work!!! Can you give any more details on the photogrammetry, and how large the team was.

 

@Magic73 : Thanks/grazie.

@pixelsteam: I'm glad you like it.

The team was very compact.
Just me (as project manager, photogrammetry expert, 3D modeller and unity developer) and my company partner (as 2D graphic designer, and ground photographer) plus an external partner with expertise on low altitude photography for helicopter and drone photos.
The photogrammetry process was done with Agisoft Photoscan and the mesh and texture optimization (decimation, polygons issues , normal and AO baking) on Blender before going to Unity.
Please let me know if you need more info.

Amazing work man! As always.

 

this is amazing. i love visiting old ruins when traveling and this gave me a nice sense of being there. museums could take exhibits to a whole new level with this instead of boring still pictures. this could be fun to walk around with a VR device like a Samsung Gear VR or something too

feedback
it's nice to hear the birds as you walk around and it adds to the natural feel of the scene. In the area shown in the attached pic, as i was reading the sign, i realized the one bird wouldn't stop singing. ever. over and over. While it ensures the visitor will hear the bird after you exit the tunnel, adding a bit of randomness (maybe after being triggered once?) , rather than just a loop, could add to the already serene natural feel. nature isn't perfect

 

Hi monkeybrainz, thank you for your words and feedback...very appreciated.
Yes, boring birds have been reduced from the final version.
The funny It that is a try to make something more natural with the adding some nest sound on a few trees but the first clip is very boring and repetitive as you said.

 

Looks extremely nice! I am just dreaming of this kind of realistic look and quality.

If possible I would like to know what are the vegetation assets used in the scene (trees, bushes, grass)?

 

Thank you mk1978!
For the vegetation i used:
- Some trees of Speedtree Desktop pack with edited textures to match the real trees in the area.
- some nice textures and mesh from Nature Pack by Manufactura K4 and Advanced Foliage Shader by Frost as shaders.

I need to create something very similar - but for buildings and floor plans.

Are you able to advise on how you created this? I need exactly the same functionality.

Cheers

David

 

Hi David,
in the first post i did some description of the developing process.
The hardest part, in my workflow, is outside unity and consist of the survey of real world data which is very expensive and need a big optimization process to fit inside unity.
In this special case the photogrammetric process gives not only the 3d information but also a full texture mapping.
Buildings and floor plans are less complex if you have the CAD projects but needs a lot of work of modelling, optimizing and texturing to obtain a good photorealisic visuals.
After that Unity give a boost to interaction and visualization and if you are more artist than programmer you can bui a lot of nice tools in teh AssetStore to speedup your work.
Cheers
Max

Edit: I see now your direct email.

 

Heh just an idea, but imagine something like this in a museum, a sort of 3d interactive archaeology thing. People would love it. Also I wanted to say it looks very good and I'm happy to be more success come from Unity
