It is very difficult to find dragons in Paris. Loving the Guimet Museum so much for his works, I took the initiative of going to search for a work that resembles a dragon. This work was the one that was the best enlightened, I captured because the amount of detail on a stone is fascinating especially when you know its date of creation.
Had to give this 500 year old wooden sculpture a try, even tho its like 8 meters tall, standing in a dark church. It is truly epic irl.
_ Saint George and the Dragon _ is a late medieval wooden sculpture depicting the legend of Saint George and the Dragon, located in Storkyrkan in Stockholm, Sweden. It is attributed to Bernt Notke and was commissioned by the Swedish regent Sten Sture the Elder. It was inaugurated in 1489.
Hello everyone,
Like SDRN, I’m from Paris. I decided to look for dragons at the Musée du Louvre. There are only a handful of those creatures over there, and most of them aren’t suitable for photogrammetry : they are either made of glass or very poorlly lit. I ended up choosing this statue by Paul-Ambroise Slodtz, created in 1732. It used to be on a building in Paris and was later moved to the Louvre.
Shooting this dragon was not as easy as I hoped : it is hanged on a wall (red circle) which means that when you’re facing it, you are well below it. Using a tripod or monopod is forbidden at the Louvre.
In order to get different point of views and to reconstruct the whole dragon, I decided to shoot from three different levels (red arrows). I used a Sony A7RII and two lenses : a 28-70mm and a 70-200mm. The 70-200 was very helpful to get some very different point of views.
Another issue was the lighting : this was a windy & partly cloudy day, which meant that the light was changing between pictures. I decided not to use fixed settings and just to try to expose each picture correctly. I know this can be risky, but RealityCapture usually does a pretty good job at blending pictures.
In the end, I’m quite happy with the result. RealityCapture created a 42 millions triangles 3D model ; this was too heavy for my GPU to display, so I used the Simplify Tool to lower the triangle count a little bit, then I created the texture and captured the video.
The theme of St George killing the dragon has been a popular motif since medieval times, symbolizing the struggle between good and evil.
This particular portrayal of the saint was produced by Austrian sculptor Anton Fernkorn. The original made its way to a noblemans palace in Vienna in 1853, although a zinc cast was brought to Zagreb. This bronze copy was placed at its current location in 1908, since when the virtuous knight has been on display killing the dragon for just over a century. (source: http://www.infozagreb.hr).

The bronze riding statue of St. George, stabbing the dragon with a spear, situated in the third courtyard of the Prague Castle, in the Czech republic. The statue stands on a high pedestal in the middle of a modern round, shallow fountain at a level created by J. Plečnik in place of a Baroque fountain which stood there originally and was taken down and moved to George Square in the 1990’s. The original statue is stored in the collections of the National Gallery, the actual statue is a copy from 1967. The statue of Saint George is regarded as one of the most outstanding Gothic sculptures in the Czech Republic. The dragon is just receiving the deadly stub right into its mouth, while its tail is rolled up on one of the legs of the horse.
Capturing:
Canon EOS 700D + 18-55 mm IS STM - 415 images taken handheld and used tripod (two focal lengths of the lens were used)
The statue is located high (about 3 m) and there were many tourists moving around. The flag is rotating in the wind.
Raw model 36M polygons and simplify to 2,5M polygons.
I grabbed the opportunity and by the apropos of this contest I reached the Museum of Marcali, in Hungary to ask for permission by capturing my favorite and most admired dragon related sculpture in my country, the Hikman Dragon.
Lucky me I got the permission and the support of the museum to accomplish the scanning.
The sculture it self was made in 1930 as the sign of Master Hikman’s locksmith workshop. The dragon sign is a man-sized iron sculpture
Béla Hikman (1887-1958) was a locksmith, but a true artist was hiding behind the craftsman profession.
His works were greatly influanced by the flow of secession, that he was able to observe closely till his years of studies in Budapest. After his studies in Budapest he moved to Marcali, where he built up his imposing workshop, the Hikman Villa, that still can be seen in Marcali with it’s several masterpiece smithworks, that all holds the signs of secession and shows true talent of it’s maker.
The Hikman Dragon belongs to Béla Hikman’s grandchildren and can be visited and seen in the Museum of Marcali.
I hope you like it!
I used 701 images
the mesh that was constructed under normal setup was 15 mill tris
I decimated it down inside RC with simplify tool to 450K to optimaze it for sketchfab.
Just realityCapture was used, I did not toched the mesh with any external DCC tool - what you see, thats how RC solved it (I used just some filtering here and there inside RC)
There’s not much dragons left in Czech republic, because saint George killed them almost all, so I had to travel like 200km to find one surviving :).
Dragon is located in Ronov nad Sázavou an it is a made-up image of a dragon that often appears in Czech fairy tales and legends. The statue is about 5m tall but it was scanned completely from the ground, without using a drone.
The name on the stone he’s holding (Apoly) is actually name of the company nearby, so his purpose is probably just to hold this ad banner. A little sad for such a majestic animal :).
Technical data about scanning process:
Number of photos: 602
Used equipment: Sony A7R + tripod (but some of photos was captured by hand)
Approx. scanning time: 1h 30m
Processing time: 12h 08m (processed on notebook)
Nr. of polys in raw mesh: 195M (processed in normal detail, would not make it in time on high)
As our friend here, Libor Telupil said, it seems there are not many dragons left, but this challenge led me to discover many and so I made a journey to pay them a visit!
During this challenge I started to see the dragons everywhere
First, I made a Google search for sculptures and heraldry symbols to find places of interest. I’ve ended up with this map and went for an incredible journey, met lot of amazing people who helped.
First model I’d like to share with you is from Lindwurmgasse - Dračí ulička - Dragon street in the Czech city Trutnov. Sculpture was created by the artist Paulina Skavova, spodní část připomínající pahorek kameník Petr Beneš
Legend has it that in 1006, the founder of Trutnov, Albrecht from Trautenberg and his crew slayed the dragon which than became a symbol used in the heraldry of this city. The city does even have it’s own museum of dragons.
This was the most easy shooting of them all, as the sculpture is publicly available, weather was almost perfect and the only challenge was to wait for a little boy to leave. He found the dragon very interesting when he saw me taking the pictures of it and started to jump all around it :).
This model is my favourite, when I only saw pictures of this dragon and red articles about the controversies surrounding location selections, protests from local citizens and members of the art community, I was not convinced. But after I’ve seen the dragon on my own eyes, I started to really love it.
Located in the small square of the Czech city Jicin, the iron sculpture was created by the artist Jiří Kmošek as his graduation work from the High School of Applied Arts in Trutnov, the aforementioned city embracing dragons. Wow, he is a talented and driven young guy!
Recently I went to Netherlands, as I was already on the hunt for the dragons, my friend from Belgium recommended me to make I trip to Ghent and scan their famous the gilded copper Dragon constructed in 1377-1378, which is now exhibited inside of the Belfry of Ghent tower, while the top of the tower is decorated with a replica.
The shooting was difficult, as there was no light inside of the tower. Fortunately, I had a chance to use the tripod, but I made the photo shooting last lot longer.
I attach to this post my entry for #RCdragons competition.
The entry I submit is a 3D model of a dragon that can be found in Ljubljana on the Dragon Bridge.
At the moment I took the photos of the dragon I was at the very beginning moment went I discovered photogrammetry. I didn’t know exactly how to do it properly so I did a lot of mistakes. I took 492 photos in a big hurry, 24 minutes, but I have only selected 424 out of them for the model but still a couple of them are not clear enough due to f-stop and exposure time. The weather changed a lot in this short amount of time from cloudy to sunny and then quite dark for sunset.
I estimate the height of the dragon to be around 5-6 meters which made is quite difficult to shoot photos of it. I handheld the camera on the tripod to take upper part photos so multiple photos I took were blurry. The model has a couple of problems regarding the wings which can be seen in the attached photos. I did clear a bit the bad parts with the lasso tool which can be seen in the attached photos.
A video made in RealityCapture can be found on Youtube:
Here in Finland there’s hardly any outdoor dragon statues. That’s why I asked help from my Vietnamese friend. He brought me a small 20 cm tall wooden dragon statue. He said the statue was bought years ago in some random Vietnamese tourist gift shop.
The wood was very reflective so I decided to use 3d scan spray. This is first time I used 3d scan spray (some of my fingerprints visible :D). In fact this is my first proper small scale scan. At my work I’m scanning buildings with drone for BIM modeling.
I also bought a cheap light tent and led panels to get the best possible result.

Another scan from my trip to Netherlands, located in 's Hertogenbosch also know as Den Bosch
small city close to Utrecht, this dragon is a part of their famous Drakenfontein, which of course means Dragon fountain. It is the famous monument of the city, erected in 1903 as a drinking fountain, but never served this function. The statue was built in memory of the twin daughters of a local esquire who both died tragically in 1881 at the age of only 17.
This shooting was the most hilarious one. When I did the research online, the pictures I found had the fountain empty, without water. Sure enough, when I arrived to Den Bosch with a tight schedule to do the shooting and return back, the fountain was full of water. I started the shooting while thinking how to get inside the fountain. First I thought i will just get in bare feet, but it was still very cold. In the end , I’ve asked for ladder in the local cafe, fortunatelly they’ve borrowed me one and I used it to move close to the dragon by doing little hops on the ladder. That day, it was the day of annual carnival and people were already in an upbeat mood, up for some pranks. One guy tried to grab and steal my ladder so I could not leave the fountain, fortunately, I’ve defended the ladder and his shoes got wet :D.
Seems we scanned the same dragon! I hope my submission is not duplicate since we compete in a different category and my post is still eligible.
Zmajski most, the Dragon bridge is a remarkable Art Noveau architecture piece inaugurated in 1901. The four dragon sculptures decorating it, were designed by Giorgio Zaninovich.
As I had so many dragones to process, to reconstruct the set captured in Ljubljana I decided to try Google Cloud Platform Compute Engine. After some trials and errors, I managed to start the virtual machine, log in with the remote desktop and install the RC. I acquired additional Steam licence to be able to process two datasets in parallel.

Dragons are around us. They are in legends, museum, art galleries…some of them are on the streets. But not only as sculptures. On the streets of Szczecin (Poland) we can meet dragons on the historical street pumps. They were built in the XIXth century. Until today people can use them to provide water (not suitable for drinking!). Why these dragons? Because they are historical, beautiful and…quite difficult to model with close range photogrammetry - they are glossy. Of course in RC everything is possible
You can find simplified model on my Sketchfab account*: https://skfb.ly/6IFOO
*I had a lot of problem with upload directly from RC. Only Sketchfab API token helped.
As there are not many dragons in Europe left and I managed to capture only five of them, I tried to think outside the box and come up with the solution for the challenge. I decided to get a box of LEGO.
With by girlfriend, we both agreed that the set we like most is the limited edition for the Chinese New year, titled Dragon Dance with the code number 80102.
When I played with the LEGO set, it always felt for me like I am inside of my creations. Now with the photogrammetry and VR, I can transcend the scales and teleport myself next to that plastic dragon and be as small as the LEGO figure.
I have a touching memories of LEGO, it shaped my technical skills so much. I wish I could say thanks again tomy mother and my grand father for all the effort and risks they take to get my my favourite toy. As a kid I never understood, why we had to hide the sets while crossing the borders back to the communist Czechoslovakia. But now I understand, how risky it was for my grandfather, who was a former political prisoner.

Hi everyone! Here’s my last minute entry to the competition.
You can find this statue in Dundee, Scotland, guarding the east of high street. It is the work of Alistair Smart and Tony Morror, and was erected in the 1990s.
This statue is based on the local Dundee legend of the Nine Maidens or The Strathmartine Dragon. Dragons are also present on Dundee’s coat of arms.
According the legend, an old farmer had sent one of his nine daughters to take water from the well. As she didn’t return, he sent his other daughters, one by one, but none of them came back. When he went to look for them, he found them dead, at the feet of a dragon. The old farmer couldn’t fight the beast, and went to the town to look for help. Martin, the lover of one of the maidens, would be the one to slay the dragon while the townfolk shouted “Strike, Martin”. According to the legend this was the origin of the name of Strathmartine , a village near Dundee.
This legend is also thought to be related to Balluderon stone (also known as Martin’s Stone), a Pictish symbol stone which depicts a dragon-like creature.
I have used a Nikon D610 camera with a Nikkor 35mm. ISO-200, f/3.5, 1/160.
*I have uploaded the model directly to Sketchfab. I hope it’s okay. I have been trying to upload it through Reality Capture, but haven’t been able to due to some sort of error (script error).

The dragon is a symbol of the Klagenfurt city and can be found in the new square, right in the middle. Legend has it that a water dragon who ravaged the neighborhood and killed the local people was killed by the Duke of Carinthia and in his honor the city of Klagenfurt was founded (it can also be translated as “lamentation from the ford”;
