Saving to E57 from RANSAC plugin

[OogieBoogie]

I'v tried this with CC 2.8 and 2.7 on 64bit windows. What I did:

I used the RANSAC plugin to find a bunch of planes from a point cloud, this worked fine. After that I wanted to save these clouds to one or more E57 files. I managed to save them as ascii files (CC automatically named the fiels with xxxx_000000.txt and so on), but trying the same procedure, but setting output format to E57 yields an error (console: [10:08:28] [E57] LibE57 has thrown an exception: namespace prefix already defined (E57_ERROR_DUPLICATE_NAMESPACE_PREFIX) ). I can save the individual planes by selecting each child tree in turn, but te amount of them makes this a bad solution.

So, how can I circumvent this issue?

Can you save the exact same selection you are trying to save as E57 but as a BIN file and send it to me? (cloudcompare [at] danielgm.net). I'll try to reproduce the issue on my side (it's probably a bug).

[OogieBoogie]

Sure enough, saving as a single .bin worked. I'll try with some other cloud that's not work related and if I can replicate it, I'll send that bin.

This was indeed a bug. You can download the online 2.8 beta version. It's fixed.

Thanks for the feedback.

Okay, now the (7z version) beta version wont run for me anymore. Popup error message:

"
...(path)...\CloudCompare_c2.8.0.beta_bin_x64\CloudCompare.exe
The application failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

Ah yes, I forgot to remove the 'CloudCompare.exe.manifest' file (next to CloudCompare.exe).

[OogieBoogie]

Ok, that was he glitch.

Managed to open the bin I sent and save it as E57. Although I had to change the path as it contained spaces and non-latin characters. Bin saving did not mind that though.

Anyway, now exporting is working, thanks.

[daniel]

Yes, libE57 (the library that handles the E57 file creation) doesn't support special characters. While BIN files are saved by CC itself (with Qt, that does support special characters).

[OogieBoogie]

Hmm.. so how come before this fix I could export e57 to the same directory that now throws an exception?

Also I can no longer open files from it, previously there was no problem whether it was from file->open or drag&drop.

Is this a trade-off situation, you can export or open but not both =)

[daniel]

No it's because there was no protection against special characters before (it's a recent addition).

What error do you get when opening files now?
