As reported on google+, stl-thumb hangs forever on my laptop.

Drivers are up-to-date and normal OpenGL support works.

Hello , i have unistalled the software but thumbnail still here ?

virusotal detects trojan TrojanDownloader.Script.iam . Can the author explain this?

Hi there,

It'd be great if there was a command line option for Windows to point this at a directory and create png/jpg/etc files for each STL.

See if we can get Rust to compile using an earlier version (whatever is shipped with Win 7). Otherwise include the redistributable in the Windows installer.

Not sure why. It works the next time if you uninstall/reinstall. Otherwise you can also clear the thumbnail cache using the Disk Cleanup utility.

I have tried to install version 3.0, 3.1 and 4.0 but none of them show me the stl thumbnails.

I have linux mint.

what does that mean, "memory allocation of 48 bytes failed" preview does not work for me

Is the source for the installer available somewhere? I am interested in creating an installer for another image thumbnail previewer. Thank you.

Hej and thanks for stl-thumb!

I'm having this puzzling issue but I'm not sure if it's a stl-thumb issue or a rustc issue.

When I build stl-thumb in debug mode it works fine, e.g.:

$ cargo run test_data/3DBenchy.stl 3DBenchy.png

But when I build in release mode, I get a segfault 🤔

$ cargo run --release test_data/3DBenchy.stl 3DBenchy.png  
[1]    1122892 segmentation fault (core dumped)  cargo run --release test_data/3DBenchy.stl 3DBenchy.png

This is on Fedora 34, with Rust stable (rustc 1.52.1).

There is a downloader trojan in the app. I checked it on a test Windows, not only does the application not work so it installed Marlin3DprinterTools, you never know what malware can be installed without your knowledge. The author, clarify the situation and not deleting posts, or should I ask this question in a video on Youtube?

Hi, I am interested in having a thumbnail plugin for our own 3D file format implemented. The file format is very simple to load, and we have C++ code that can load it into memory. I was wondering if you would be available to work on this, later this year?

The plugin works fine, just installed on Ubuntu 20.10
libosmesa6-dev libosmesa6 are required, but not installed by the .deb
Thank you.

I tried to build from source on my Synology NAS but I'm running into linker errors and it looks like it's just not going to fly (at least with my skill level with build systems, gcc, and rust).

Would it be possible for you to roll an x86_64 GNU/Linux version and add it to the packages?

Failing that do you know of a place where I can diagnose: "error: linker cc not found"
gcc is installed and available, but when I symlink cc to gcc the cargo build step fails differently. I suspect there's just some essential build tools that aren't available on the NAS

Greatly appreciate your help. This tool was great and I bought a NAS specifically to make use of it, and then realized too late it was the x86 version and not the ARM version (facepalm)

KDE/Dolphin has it's own ThumbCreator API :(
https://bbs.archlinux.org/viewtopic.php?pid=1556175#p1556175
https://api.kde.org/frameworks/kio/html/classThumbCreator.html

Why don't you offer this? Would be pretty useful to many. Thanks!

It possible for stream stl as standart input, not as file?

I tried to build from source on my Synology NAS but I'm running into linker errors and it looks like it's just not going to fly (at least with my skill level with build systems, gcc, and rust).

Would it be possible for you to roll an x86_64 GNU/Linux version and add it to the packages?

Failing that do you know of a place where I can diagnose: "error: linker cc not found"
gcc is installed and available, but when I symlink cc to gcc the cargo build step fails differently. I suspect there's just some essential build tools that aren't available on the NAS

Greatly appreciate your help. This tool was great and I bought a NAS specifically to make use of it, and then realized too late it was the x86 version and not the ARM version (facepalm)

I was very excited to find this project as I'm in need of an STL thumbnailer. I'm running gentoo on x86_64 hardware so I had to compile and install manually. However, the compile binary refuses to work. Based on searches it sounds like it's an issue with winit and my version of Rust (1.51.0). I tried using various versions of winit but I hit the same issue with all of them. Here's the stacktrace:

I would think if it's a compatibility issue with Rust then everyone running a recent version of Rust would be having this issue.

I would like to know, how can I delete the stl-thumb from my Windows safely?

Running 0.4.0 on Ubuntu 20.04.

Many STL files do not generate thumbnails. When I try to generate a thumbnail on the command line, I get:

$ stl-thumb retainer_thick_112414.stl foo.png
ERROR - Application error: failed to fill whole buffer

Example STL file attached:

retainer_thick_112414.stl.zip

I am currently working on a 3d file management software and am looking for an performant way to create thumbnails for 3d files, as doing this with C# is not feasible.
Are you able to estimate the effort it would take to expand the project to support thumbnail generation by command line? I don't need anything fancy, just a object path and a thumbnail path as parameter and it should generate the thumbnail at the given location.

Of course I am willing to learn Rust (never done it before) to implement the feature myself and credit your project in case this is feasible.

Hi!

I've installed this through the AUR and it only kind of works, the generated thumbnails are always white unless the "-x" option is passed to stl-thumb (this happens in both the command line and through my file manager, pcmanfm).
Not a huge deal but a bit annoying :)

dpkg-deb: error: 'v0.4.0-stl-thumb_0.4.0_amd64.deb' is not a Debian format archive.

Currently, if you run stl-thumb on a fully headless server, so no X11/Wayland installed, only accessible through ssh, I get the following error:

⟩ stl-thumb 32mm.stl 32mm.png
thread 'main' panicked at 'Failed to initialize any backend! Wayland status: NoCompositorListening X11 status: XOpenDisplayFailed', /home/user/.cargo/registry/src/github.com-1ecc6299db9ec823/winit-0.26.1/src/platform_impl/linux/mod.rs:619:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The app can be run by using xvfb-run:

xvfb-run stl-thumb 32mm.stl 32mm.png

Which generates a thumbnail correctly. This is on Arch linux.
Figured it might be of interest to anyone passing by trying to run this on a server for example.

Also, amazing tool, there are surprisingly few ways to quickly generate a png from an stl.

Hi, i try use this project for generate thumbnails on win10 VPS
Have next problem

Seem so they have OpenGL 1.1.0 version
Shaders in src have 120 version

It possible make support for 110 version of OpenGL?

Hi, awesome app, nice feature will be if it will also preview a "*.3mf" files

Hi
Can you give an example to how change stl color preview to gray in windows 10?
thanks
yoav

After installing this on a 64-bit Ubuntu 16.04 with the MATE 1.12.1 desktop environment and the Nemo 3.6.5 file browser set as default, the thumbnails show up as text document icons instead of graphical representations of the STL files. In Nemo's settings, I Preview File Size is set to 'under 5mb', but I also tried raising that to 'under 10mb'.

This is the error durring installation, and all i can do from there is cancel and exit out, no thumbnails work.

I can't get stl-thumb to generate any thumbnail on the Win 10 (1909 18363 and 20H2 19042), I tried it on two notebooks.
The error message I get is the same on both, namely

I'm not exactly sure what causes the problem, but here seems to be the corresponding line that throws the exception
https://github.com/rust-windowing/glutin/blob/v0.18.0/src/api/egl/mod.rs#L546

It seems to be something related to OpenGL... one of the notebooks has an Intel HD 520 and AMD Radeon R7 M360, the other one a GTX 1060 grapics chip.

Hi,
This looks great and I am trying it out on Ubuntu 16.04.4 with xfce. I installed your deb and the command line program works fine. The file manager says the stl files are type model/stl but I am not getting any thumbnails. I restarted Thunar. Any idea what I can check next?

Thanks.

hi,
would it be possible to provide centos support ?
i got a script that shows STL files in the browser , but i need this plugin to show thumbnails of the STL files

Thank you
Greets from PowerChaos

I've installed and reinstalled several times and also repeatedly reset the thumbnail cache, all to no avail. I'm still just seeing the icon for prusaslicer that I have set as the default app. I also don't notice any thumbs.db showing up in my folders. I had my son install it on his computer as a test and it worked fine, so it must be something with my Windows setup or some other add-on I have installed. Would actually be nice to see this work.

I recently installed 'stl-thumb' as a thumbnailer plugin to the file managers, but I notice that it isn't converting all files with the .stl extension. Upon closer inspection using the shell 'file --mime, the files that are "working" are binary encoded STL files but the ones that are not are ascii encoded STL files. Testing the script from the command line, however, shows that it works on both types of files.

Building a wrapper around the stl-thumb binary script archive so I can drop a log, I can see that it is not even attempting to do anything with the ascii encoded files. So I'm assuming it's something at the OS/file-manager level seeing those files as different.

The modified thumbnailer definition file is currently (stlthumbnailer is my wrapper script that simple logs the command being called then grabs any errors - no log entries show up for the ascii encoded stl files):

[Thumbnailer Entry]
TryExec=stlthumbnailer
Exec=stlthumbnailer -f png -s %s %i %o 
MimeType=model/stl;model/x.stl-ascii;model/x.stl-binary;application/sla;

When I pull up properties for both types of files in the file-manager, the mime types listed for both show up as:

Unknown (model/x.stl-binary)

Checking from the command line with file however shows:

$ file --mime *.stl
binary_test.stl:   application/octet-stream; charset=binary
ascii_test.stl: text/plain; charset=us-ascii

$ file -b --mime *.stl
application/octet-stream; charset=binary
text/plain; charset=us-ascii

Again, the thumbnailer script runs on teh binary encoded file, but doesn't appear to be run at all on the ascii encoded one. So I'm assuming it has either something to do with the mime types or the difference in content. Running the script manually on the ascii encoded file does work fine.

I'm not sure what to tweak to get it working properly.

Like the title says, an error message says the software is already installed.

Here is what I did, because i had a slicer generating stl thumbnails too I uninstalled STL-Thumb and the slicer.

Now when i want to install STL-Thumb i get this error message.
I'am not able to find anything in the registry either.

Icons are generated fine in the normal windows explorer pane. But when clicked on there is no preview or large image in the preview pane.

Hi, I can't see the previews in Xyplorer, an alternative file manager at Windows 10 Explorer. I added the clsid of STL-thumb to Xyplorer, as I did for other types of extension, but without success. The previews are only loaded if you create first with Explorer.exe.
Windows 10 x64
Xyplorer 21.90 X32 (not available at 64bit).

This plugin works great for me in Nautilus in Gnome in Arch for thumbnails, but I mostly look at my files in list view and hit space to open the Sushi preview. Unless I misconfigured something (entirely possible), stl-thumb images are currently not showing in that preview window.

Hey! How do I change the color of the model?

AVG worries about the installer, then says things are OK, then worries about a new EXE that the installer spawns, then says things are OK, and then the installation fails. I could find no way to add a comment to the thread about this under 3D printing. Google Plus remains unfathomable to me.

Why not? I am really in a horrible situation where I need to support that as well and there's no option. You would do lots of good by offering a path to that.

Hello,
Love the program. Switched from using a botched together openSCAD script to this and it is much faster for producing images from STLs.

I was wondering if it might be possible to specify the angle the image is taken from. I am looking to do some thing in a more traditional isometric.

I've been spending some time trying to get this to work with Nautilus on Fedora 32, and I've been having some difficulty. I copied the stl-thumb-mime.xml and stl-thumb.thumbnailer files into the proper directories, and it seems that the thumbnails are failing. I check ~/.cache/thumbnails and it confirms that stl-thumb is indeed failing.
I tried to run the program directly using the same arguments found in stl-thumb.thumbnailer, and it was a success.
Moving on from there I turned on debug logging in nautilus and enabled the full rust backtrace and I get the following:

Because library libOSMesa.so that this thing uses is not there, libosmesa6-dev should be added as a dependency.

Just tried new version, it says:

ERROR - 0:1(10): error: GLSL 1.20 is not supported. Supported versions are: 

thread 'main' panicked at 'Compiling shaders', src/lib.rs:110:13

I'm not sure who's fault this is, but just in case:
I'm using Nvidia GTX 960 with 390.116 driver on Xorg 1.19.6
I do have some Intel integrated GPU, but it is diabled.

Would be nice to have an option to generate thumbnails of different color without recompiling this nice thing.
