Can't open E57 point clouds despite plugin installed

[subo3]

I have built and installed CloudCompare with the PLUGIN_IO_QE57 - plugin. Still CloudCompare does not open E57-point clouds.

Are there other dependencies apart from the plugin in order to open E57 files? The build worked fine with XercesC v3.2.3

Thanks for any advice!

Hi subo3,

If you have pano images in your E57, my suggestion would be to export WITHOUT images. I'm not sure if this is specifically the problem with Cloud Compare in your case, but I have seen incompatibility with pano imagery in other applications.

I understand you might want the images, the purpose is to eliminate them as the source of the problem.

Hey, thanks for your answer. Unfortunately my problem is, that somehow the plugin is not "activated" or i don't know. It's not like CC crashes when trying to load an E57 file, it simply doesn't offer the option to do so:

It does not show the plugin in the plugin manager, but the other plugins work fine:

But there were no error messages when building in cmake. After building, i installed via
cmake --build . --config Release --target install

I'm using the Windows .EXE, its appears that E57 is not the only format that is missing from your list.

In the Console of CloudCompare (F8), do you seen some error messages about CC failing to load some plugins maybe?

Depending on how you compiled the plugin, it may have dependencies to DLL files. These DLL files needs to be found via the system PATH variable, or they have to be copied next to CloudCompare's executable.

Thanks, actually there is an error message: "QE57_IO_PLUGIN.dll does not seem to be a valid plugin (Cannot load library C:\Program Files (x86)\CloudCompareProjects\CloudCompare\plugins\QE57_IO_PLUGIN.dll)"

I copied QE57_IO_PLUGIN.dll from "/plugins" next to the executable, but still the same error message pops up. Is there anythings else i can do or have to do?

Thanks a lot

No, the plugin DLL should stay in the 'plugins' directory.

It's the dependencies that should go next to the executable file. You can use the 'Dependency Walker' tool (https://www.dependencywalker.com/) to check what your DLL is expecting. Probably the Xerces DLL and maybe some others.

Thank you, it works now. Only the xercesc-DLL was necessary.

Hi, I am completely new to Clod Compare, I am trying to open an E57 file and I am getting this message, can you maybe help me to understand what should I do in order to open the file properly? Thanks :)

Can you share the cloud with us maybe? (to admin[at]cloudcompare.org)
