The sketch also highlights some data bottlenecks. These bottlenecks are steps through which all the data necessarily goes at some point, and so they are privileged entry points for our extraction exercise. All of that being noticed, it is a bit trickier to get than a nice "Right Click, Save As".

But for a 3D model, there are so many different aspects to play with than each player has its own way of storing data. Its own private file format, if you will. If we want to interpret correctly the raw data, we must know how it is used by the player.

In a way, the code of the viewer is part of the model. There have been efforts to standardize this a bit, with the GLTF format , now in version 2. This is the format used to embed 3D objects in Facebook posts for instance yes, you can do that.

It is a great file format, that handles many usages of 3D models, but viewers playing with bleeding-edge rendering tricks will always need some extra options. If you are used to offline 3D models formats, you can see the GLTF as an interchange format, similar in usage to Alembic of FBX, but specific softwares will always need their own.

Before heading to Google Maps, we will study a much easier case, namely Marmoset Viewer. Its source code is much lighter than others and more self-explanatory. This will help us to understand what data we are looking for and which challenges we will face, as well as introduce some useful tools.

Troughout this section, I'll be inspecting Marmoset Viewer's homepage. We will try to get the model of this nice fox:. So, what is a 3D model actually? There are theoretically many different ways to represent a 3D model, but when talking to the GPU, they must all boil down to two pieces of information:.

So our goal is to find these two buffers of data, and export them in a format that a 3D software like Blender can handle. The web browser is an interesting environment. It must be very transparent, and allow for precise debugging, because website developers must ensure that everything works well, and troubleshoot efficiently when they run into problems.

So all the major browsers feature a good page inspector , often accessed by pressing F Among the numerous tools provided, the first one that will help us is the Network Monitor.

It displays all the network queries that the inspected website triggers and their responses. If the client's computer gets some data, it must be displayed here.

And there is no way for website to cheat on this, since all queries fired from a web page are actually asked by the page and effectively performed by the browser, so the browser knows it all. When loading Marmoset's home page, there are queries emitted. How are we going to find which one contains the data we need? A very good hint is the file size. Another one is simply the file format. All the fonts, style sheets and images are not useful to us we'll get to textures later on, and anyway Marmoset does not load them through regular image files.

When sorting queries by descending size, one of them clearly stands out: vivfox. A file of 4. And it is the only file with a weird extension. This must be our data. Yet we need to understand it, because for now it just looks like a large binary file. To this extent, we'll have a look at the marmoset. Since the copyright notice allows it, I shared the file in a gist.

This looks horrible, but just because all useless blank spaces have been removed for a more compact file. The good news is that it has not been completely obfuscated, so function names still make sense, although some variables have been replaced with only a , b , c , d , etc. This will help us understand what we need. And fortunately, since this is very common with JavaScript sources, the browser's inspector provides a code prettifier , in the Debugger tab:. The best to do after running the prettifier is to copy paste the code in a more comfortable text editor of your choice, because the source is more than 6k lines long.

NB: I cannot share with you the pretty version of the code, as it would violate its copyright notice, but I invite you to reproduce these steps because I will refer to the line numbers of the pretty version. If you have some time ahead of you, I recommend you to read this code.

It is clear enough and implements many features of a modern physically based 3D viewer. You can check out the shaders at the very end. But you certainly don't have such time.

So let's jump to the essential. We need to find where the data is interpreted into 3D vertex attributes. Our best entry point is to look for network queries. The mview data file is loaded by the viewer, so there must be somewhere a call to the JavaScript function that does that: XMLHttpRequest.

Since the marmoset viewer is a standalone script, it does not hide this in any complex third party library, so we can use the search function of our text editor. Four of them are in the functions GUIRegion. We don't care about these. The other one are more interesting: they are in generic functions fetchText , fetchBinary line and fetchBinaryIncremental.

The first one is of little interest to us, but the binary related functions are very promising. The function fetchBinary is called at the end of WebViewer. A quick look at the content of fetchBinary suggests that its arguments are callbacks , and in particular that its second argument is a function called when the file is fully loaded, so we will focus on this. In this callback, we can see line that the data is passed to scene.

This suggests to look at the class Archive , and at the load method of the Scene class. The Archive class is defined at line , and it looks a bit like a zip decoder. It reads a succession of concatenated files, decompress them if they are compressed, and store them by name in its files attribute. At this point, it is time we download the mview file and have a look at its raw content. You can get the address of the file vivfox. If your browser does not let you download the file, here's a trick.

What can we do with a binary file we know nothing about? We can naively start to read it as if it were a text file. If you don't want to open a 3 Mo file that may actually not contain readable characters in a text editor, you can also simply display its first characters using the head comand in a bash terminal:.

Obviously, the mview file is not a text file, so most characters are unreadable. But we can already notice the thumbnail. Let me introduce another critical tool for binary inspection: xxd. You can pipe the output of head to it, like so:. This prints the same data in two different format. On the right-hand side is the file interpreted as text, or a dot if the character is not recognized. On the 8 middle columns is the very same information, but displayed as hexadecimal numbers.

There is exactly 16 bytes of data per line, and the left-hand column shows the position in the file, in bytes, formatted in hexadecimal. We can thus notice that there is a null character between "thumbnail. Everything matches! More interesting, we can interpret the bytes following the strings. The next lines of the Archive code read 3 unsigned integers, laconically named c , d and e.

The few next lines show that d is the number of bytes to read from the archive, c is a boolean specifying whether the file is compressed, and e is sent to the decompress function. The latter is actually the decompressed size of the file. This is great, because even if for now we cannot decode the archive, we can already list its content!

For a quick test, I like to use Python and its handy struct module. For instance, struct. This is how the beginning of the output looks full version :. The files can be viewed on Daydream View or Google Cardboard.

Using the downloadable objects, you are allowed to create animated GIFs directly on the website. Visit: Google Poly. Also known as a 3D model database, the website contains nearly 4. Bear in mind that 3dMdb is not a repository, but only a search engine that links to several dozens of 3D model shops and libraries.
