Horos 3D module Export functions are not working properly

[David Wang]

4.0.1 ver. Horos running on MacOs Sonoma 14.2. The movie capture by Fly Through and Movie Export also JPEG still image are only left lower corner and with a weird wide screen like scale. 

This is the working window looks like:

And this is the export result (either still image or movie export, or fly through are the same):

Is it the setting's problem or some bug?

[James Chen]

I've experienced the same problem as the person who posted this email. It's been 2 years since the first posting. Are someone in Horos Group thinking of solve the problem? 

thanks.

I've had trouble with horos, and I'm trying to get past the learning curve for 3dSlicer, which seems to be really powerful, and very actively developed.

The volume rendering feature of horos relies on an old version of a library called VTK. This version of VTK uses openGL as its graphics API.
As you know, openGL has been deprecated, and it is now recommended to use metal as the graphics API for Mac applications.

As this is the current situation, it is not easy to maintain the 3D volume rendering function.

Using the new Metal-enabled version of the 3D slicer is a good alternative to horos.

A better option would be to call the volume rendering functions written in Metal directly from Mac's apps.

We've created a test app and made it public, so please use it as a reference.

Interesting interesting but not available

 

It's strange because I'm using this version ( Sequoia version 15.4 ) which is supposed to be compatible

Sorry, our phorlix lite  is only compatible with Apple Silicon.

It is possible that Horlix might work on an Intel Mac, but since it has not been notarized by Apple, you may have trouble installing it.

Ok I will do a test as soon as possible

 

Do you happen to know of a lite version of a viewer compatible with Mac as was the case with Weasis?

 

I mean a viewer that can be burned onto a CD, for example, and which can be used to view studies.

 

Regards

 

Marco

i don't know.

Phorlix lite uses a library called dcmtk to analyze dicom tags.
The reason why Phorlix lite only works on Apple Silicon is because the dcmtk was only built  for Apple Silicon.
It will probably work on Intel Mac if you build dcmtk for Intel architecture.

Traffic seems to have stopped... :-/

I think the build system of the horos project is a bit too complicated for beginners including me.

For example, it uses shell scripts to get the libraries like:

>path="$( cd "$(dirname "${ZSH_SOURCE[0]}")" && pwd )/$(basename "${ZSH_SOURCE[0]}")"

>cd "$TARGET_NAME"; pwd

>

>env=$(env|sort|grep -v 'LLBUILD_BUILD_ID=\|LLBUILD_LANE_ID=\|LLBUILD_TASK_ID=\|Apple_PubSub_Socket_Render=\|DISPLAY=\|SHLVL=\|SSH_AUTH_SOCK=\|SECURITYSESSIONID=')

>hash="$(git describe --always --tags --dirty) $(md5 -q "$path")-$(md5 -qs "$env")" 

(in Horos->Scripts->DCMTK->CMake.sh)

For those without skills about shell script, this may be hard to understand.

However, the great open-source libraries that make up horos can be built independently.

Of course, dcmtk can also be built independently using CMake.
See: https://github.com/DCMTK/dcmtk/blob/master/INSTALL ,dcmtk_cmake.png, ...

All you have to do is specify the parameters according to your environment and purpose and build it.

Sorry, I posted by mistake...

But this is a good opportunity to explain. 

libdcmtk.a in the project's lib folder is the dcmtk built for MacOS. 

Once you can build dcmtk, it's not difficult to call dcmtk functions on xcode.

>    dataset = dcmfmt.getDataset();

>    

>    const char *string = NULL;

>    //Patients Name

>    if (dataset->findAndGetString(DCM_PatientName, string, OFFalse).good() && string != NULL)

>    {   printf("Input File: %s\n", ifname);

>        printf("Patient Name: %s\n", string);

>    }

If you build the project, you'll see that it's a simple command line tool that simply extracts a patient name
from a specified file.
