 So, okay. Hi. Or good morning for most of us. I'm Martin Koshtel and I'm here to talk you something about the archaeology and 3D models and how it works and what I do. So there is some main topics that will be discussed. It's about my department, 3D atelier where I work and study also archaeology, something about virtual archaeology, how it works, what's going on here, what type of data sets are available for 3D and 3D modeling, rendering and so on. And as a final, there will be something about the project archaeo models that I start. So you can hear, there you can see the location of Bernal, that's the second biggest city in Czech Republic and in this city is really cool university called Masaryk University. This university at Faculty of Arts, there is a department of archaeology and museology and there is, we've got the 3D atelier where I work. Our specialization is in the spatial documentation, 3D modeling, archaeology co-visualization and main workflow is in photogrammetry or image-based modeling as maybe you know and spatial analysis and 3D modeling. Here's some photos from the sites when we're doing documentation. So if we are doing virtual archaeology or archaeological visualizations, we must work with archaeological data sets and use them as a reference but we are more scientist than 3D models so we must use a huge bunch of softwares to do it easily and quickly because we haven't got time to do everything in blender. So what we do inside in blender? We are doing modeling, also retopology of the 3D scans, we are doing sculpting, optimize everything for, roads for scanning, analyzing, rendering and animation. So that's all, that's a joke. Here is some 3D scans, we are doing 3D scans of artifacts like pottery or iron things or scans on site so it's documentation for archaeological analysis and creation. Also we are doing reconstructions of the artifacts to popularize archaeology for people, even more reconstructions and not only the artifacts, we are doing reconstructions of the whole sites and even castles. So what's the virtual archaeology? This is the term that used power Rayleigh in 1990 and it's the usage of computer-based simulations of archaeological excavations. It's mean just classical visualization as we know but in archaeology there is two main ways, there is photorealistic renders that's only for popularization of archaeology for the public and also there is scientific renders that show the, how to say it, the validation of the data that create the visualization. Basically in archaeology visualization there is three basic LODs in the modeling, there is classic shape reconstruction, there is second is virtual visualization, that's mean we've got the basic, it's almost the same like architectural visualization because you've got the basic construction, it probably work that construction but you cannot use the construction or 3D model as a plan to rebuild or whole building in the real world and it's the same with the materials and virtual reconstruction basically it's the reconstruction of the whole thing and you can take the 3D model and build it in real world. So we always use virtual visualization because we always do huge arreals and there is lots of models and in two people it's really hard to recreate everything to the detail. So I've got here some case studies that I done. First is Rockstein Castle, you are looking to do LiDAR data, Rockstein is castle and castle in the valley, it's a specialization, it is here and I done the reconstruction of the state from the 13th century for my bachelor thesis, I use Blender as a main modeling tool, Unreal for rendering because that's a huge area and substance painter for texturing. So this is the look like, how it looks today, if you look to the plan the black spots are the remains that was been archeologically found in 13th century, no from the 13th century and this is the input data that I start, basic input data that I start with, sorry, this is the data that is in the start of my modeling. So to recreate it perfectly I choose to create a landscape not only for LiDAR data but create a smaller piece that will be much more precise so I choose photogrammetry for this but when you are working with photogrammetry you know it, sometimes you don't catch everything and you've got holes in the data and that's not good. So I decide to just fly around the castle, create really basic model to know where is vegetation, where are buildings and so on and this basic, I start planning my route. So the first thing to have got good photogrammetry result is a good overlap of the photos and second is ground sample distance, do you notice ground sample distance, no? That's how many pixels are for one centimeter at the photo, that basically means the resolution. If you take a photo of the texture and you take a close-up you will be really high details and so on but if you take a photo of the doors that's only black hole and nothing, no details. So that's the ground sample distance and if you are doing this type of scanning you really need the consistency in ground sample distance. So I wrote this, write this really basic script, take a NURBS, place a camera on that, take the parameters of this camera because the GSD depends on the parameters of camera which you use for photogrammetry and then I play animation when the camera project the black and white squares to the model and that's visualize me the ground sample distance. This is the basic visualization and that's mean in the center there is really small squares and as I said at the end of the picture there is really big squares and not so detailed at that. So I create this road for every part of the castle, every tower and wall and that helps me to reconstruct these 3D models and 3D reconstruction and create documentation of the buildings and also of the terrarium because I can filter that out. Here is some other scan of the some environment from the location as you can see I use a blender for retopology and baking normals and here is a red textured model in Substance Painter. But if I want to put my data into blender I mean GIS data, you know what is GIS, Geographic Information Systems, yeah yeah perfect. So if I want to put this data into blender I must use GIS add-on, that's a perfect add-on I absolutely recommend it, it helps you to import also LiDAR data but the shape files and so on from all of your data from the GIS GIS. So there is LiDAR around and this detail model is taken from photogrammetry, I place it in blender together this. Then I use shape files from the documentation from the parts of the 13th century that's the red points and then I can start doing reconstruction exactly on the side. And looking for some nuances doing analyzing this thing and so on. So here are some examples as I work, I must build a bridge that was detected archeologically, there is some visualization how it can work and it's based on the archeological data from the rich land, so that's research from 1980 I think and they found a whole bridge under the surface, yeah that's the word. Okay there is another thing like buildings and towers and constructions and about everything the archeology can tell us how it looks. So we've got really huge collections of the ground planes, in Germany's Grundris I think. Also there's found of real constructions from the 13th century or 14th century in Czech Republic that's fantastic and this basic I can start building and doing reconstructions. Here is some examples how it looks in Unreal Engine and now let me jump to the Unreal Engine I will show you the final data because I must import data from Blender to Unreal and it's me in the Terrarium 2 and so on. So if I look quickly you will see that's the really huge LiDAR data, the texture is not so good from this area but I do some close-ups. Basically I used the Unreal Engine because it has got LODs and I can use lots of agitation and in 13th century in highlands in Czech Republic there are lots of agitation so I choose Unreal Engine for this and this is the landscape how it looks like on the place and there are some nuances and how it can look. I will slow the camera a little bit. Okay there is the complete structure how it can look and if I filter the buildings you will see only the landscape. So if I want to import my LiDAR data into Unreal Engine I must use the hate map and recalculate it and it's not really good I must discuss with the Unreal guy that was here and it's really complicated to get exactly LiDAR data into your scene. In this point I just used my photogrammetry model, place it here and just scaling the hate map to match my photogrammetry model of the landscape. So this is about the Rockstein castle and next is virtual arc project that's an international project for valorize archeological locations and show them because classical archeological location is just a field because everything is underground. So we create a virtual guide for the mining center from 13th century to use Lumion as the rendering engine because the scientists from the department of archeological of Czech Academy of Science use it so I must prepare everything for Lumion in Blender and also we have Sketchup for quick sketches to discuss it with scientists because it's much more and they understand it better I don't know why they like the Sketchup models but they like it and there is some quick video it's the application for the mobile you just came to the location hit the point where are you and just you can look around to you and read some descriptions on it that's the educational part of the application and there is a storyline for the small kids because kids are real like games unfortunately and it's the story itself is not so big but it's classically if you know game books that works same so there is some you for this from this and we can continue to reconstruct views also next you know data like dendrology that's tell us something about vegetation geological profiles to tell something about the vegetation also we use geomagnetical measurement so we are able to reconstruct buildings exactly on the place they are they was without digging and also we will slide our data and some analogy to start building this is some example model how buildings looks like it's a motto and it's something like low cost medieval castle in the medieval it's just the building on the bike with some the vengeance around it and there is wife rhyme we really use basic geometry but combine it with some scans and normal maps and it allows us to create really nice-looking but still is it result second is to know this on this picture you can see the workflow of sketch up and blender and the left side there is the sketch up reconstruction quick how the or mill can look like the mechanism and on the second there is 3d reconstruction of that model inside the blender this is rendered in blender in cycles I think or I'm not sure now and of course there is samples processing on it next picture the charge from the location next visualization that we created for this with the grass fault that's cool add on and also we must create humans so we have got some concept art that we must use as a basic shapes and we just again we use the optimized topology sculpt or the face and there is final model and and has got the problem he cannot upload the animation so it's just this so-called sculptures there is some references for landscape such as later that a clondike or highlands without woods and when we build the of course there is some later visualization and this is the site how it looks in a real life I'm sorry also we use illuminations for to see how it works in a past and then we can start to construct the actual landscape we was particularly LiDAR and it's the ends we use only hate map from the Google Maps Google art so we start building some ways placing the buildings placing the other vegetation and this is the final results I've got a quick video for you so this is the mining site from the 13th century in highlands in Czech Republic as you can see there is lots of buildings and this is the ends of the mines that bikes there is some 3d characters rendered in Lumion it's not I don't actually like Lumion the characters not cool in that but they want to use it so I'll do the best to recreate it but for landscape Lumion is really cool it's really fast rendering and for scientists I think that's the way for the scientists so that's the end of the showcase from this project so why is important to use exerdata as a 3d modular because time travelers that's mean if you are modeling something and saying that's a little bit something like historical thing or medieval you can't you cannot take things from the 11th century and place it sorry you can take things from the 17th century and place it to the 11th century because for lots of people it's like that guy from the 1880 year 1980 years in 1930s it's the same if you you cannot take Lamborghini place it into the 1930s and say this is the reconstruction of the past or this is the 1930 render because everyone tell you hey man Lamborghinis are not in 1930s so what kind of data sets is fine for 3d modeling it's really it's depend what period period really doing is if you are doing prehistory or you are doing medieval things but these data sets are fine across all periods the first three are really cool for the landscape that can tell you something about landscape how it looks like in the past second is experimental archaeology archaeology sorry and the quantization of artifacts that's cool for tools or buildings and the last one are Borneo archaeology and anthropology I really don't go in the deep in the last part here so I will quickly describe it here Borneo archaeology can tell you something about the social structures and social position of the human in the past and anthropology can tell you lots of about the hate and weight and how they looks like but this is more archaeology anthropological things and I will not discuss this here but I will tell you something about the landscape archaeology because it's cool landscape archaeology basically can be LiDAR data UF or UAV photos or classic photos historical maps dendrology and if you look to this picture there you can see the site probably from the analytic period and there is lots of buildings and so on and in it can looks like this part that can tell you this is the vegetation vegetation science that mean where is building the vegetation grow different next are photos from the 19th century that's called archaeology of modernity also and and these photos you can see how the city or villages works and you can see all these small roads and every part of the past life and you can really analyze it next one I LiDAR data I'm not sure do you know what is LiDAR data someone knows someone not LiDAR data is the basically is the scan of the terrarium and it works how you can see it here the plane has got the sensor sent lasers point down then register it and because the plane and sensor know its location and rotation it's available to measure the terrarium and it's cool because if you've got this type of woods you can say okay it's only woods and it's not interesting but if you look it in LiDAR you will see okay there is some structures and if you will read something more about the location you will see okay it is the prehistoric files in the England wow it's interesting and it can tell you how the landscape look at that area and you can recreate it in your visualization it's good resource next is that mining area that I say show you and you can continue yes historical maps there is lots of historical maps especially from the 18th century or occurs maybe for the half of the Europe and they tell you about the usage landscape usage so our fields where our grass where trees and woods and so on so it's really good if you want to do something in medieval age it's almost the same because this type of parcels are in the medieval too and how to get these sources there some links there you can find them don't be scared that this until that point see that it's checked sites but in English also and perfect thing for the for the what not for reconstruction for if you use it the data as a reference yes for the referencing is server academia point edu where you just type that thing that you are interested in and this server find you scientist scientific scientific articles about that and you can imagine how it works and then you can recreate it and also I've got the dendrology in the landscape archaeology because that's tell you the everything about this piece she is that of the trees and quickly there is a geology and settlement archaeology that tells you everything about settlement how it works how it looks and something about the ground planes of the buildings and you can start doing reconstruction like this because it's a little bit tricky because settlement archaeology can tell you lots of things about the distribution but you must do lots of researching and expert look to the experimental archaeology how look that things that are about the ground about the ground for this I just picked these two big projects that you can just search and look at them there is lots of settlements and so on and you can read about it and use it maybe as the reference and the last thing is documentation of artifacts the condition of artifacts can tell you the generation of not generation but how artifacts are created and how they are about something about their their types and rotation you can use this classical drawings and so on but it's it's not good so our department has got a huge library of 3d scans of vessels and so on I can show you on sketchfab here so basically it's something about one or more hundred scans that you can use as a reference just type it actually it's in check but we are working to recreate it for recreated translate it to English and it's in sketch fob so you can rotate look at how it's created and use it as 3d reference that is not modelled that is scannet okay and the last thing that is really cool for artifacts are illuminations I've got another type for you that's this site that's full of illuminations with the notation and illumination can tell you lots of about the characters landscape as you saw and so on and here only on this picture you can see the style of the dresses weapons how look armor how look under dresses clothes and so on it's really cool if you just starting analyzing it I will show this again in this manuscript is you just type search choose your location where are you from and maybe for this need runs just type search and then it shows you tons of and tons of illuminations with the station and if you click it you can go to the original file to the libraries and have got the all data that is that you can have got for the illumination okay so I'm almost in the finish so there is experimental archaeology how in experimental archaeology can tell you how I said the things how that looks about the ground and so quickly about project are co-models I started this project as my master studies thesis and it's based in creating of 3d high quality 3d scan or models that will be described from which period they are and you can after that you can download it so there are some examples of this is kind of armor from the medieval it is a 3d scan retopologized optimized and there is also this kind of boots our shoes sorry yeah and that's the main idea what we will what I will do here is some art if another artifacts or even sports will be here so thank you for your attention have a nice day use your power as a 3d artist to popularize everything from the science
