CloudCompare forum

Hello Daniel,
I have several (~500Mb) files that will not open with either 2.6.2 or 2.63 beta - they crash CC during the opening process. They can still be opened with 2.6.1

It's difficult to tell why, the files contain multiple clouds, primitives, meshes etc. so I cant really tell what is causing the problem.

Regards

Hum that's weird. There was an issue in the 2.6.2 version with clouds bigger than 300 M. points but it should be fixed with the 2.6.3 version).

Can you send me one of the files maybe?

Hi Daniel, I've emailed one of the smaller ones to your gmail account..... let me know if you don't get it & I'll try something else.

Regards

Okay I found the bug. I changed the internal way of coding cylinder primitives without thinking about backward compatibility. Therefore when reading the file CC would find an unknown object type... and would eventually crash because this case was badly taken into account :D

Everything's fixed. I updated the online 2.6.3.beta version. You should be able to load the files again now.

Sorry for the disturbance...

Yup,

That's squished the bug alright.... all my files now open.

Thanks Daniel, that's amazing.

The above happens when I try to import a .PLY file. Basic functions such a primitive create work OK

Happening on versions 2.6.0 2.6.1 2.6.2 32 Bits Windows 7 Home Premium with all patches current.

Can you generate a 32 Bit Beta version for me to try?

Does it happen with any PLY file or a specific one? If it's a specific one can you send it to me?

Otherwise, if it"s happening with any PLY file, have you tried with another file type (OBJ, etc.)?

And last but not least I believe ig4icd.dll is an Intel's graphic card driver. Have you tried to update the driver?

Thank you for the prompt reply.! The crash occurs with any .PLY file and the point cloud briefly displays on the screen before the crash. So it looks like the problematic Intel graphics driver is the culprit. I will try reducing the resolution as well as seeing if there is a newer driver. I had similar issues with Repetier Host and had to reduce the graphic resolution in the Repetier Host APP itself to work around the issue.

FIXED !

Under display options, I unchecked

" Try to load clouds on GPU faster display" option and voila, ply point clouds and stl files load fine now.

Thank you Daniel for pointing me in the correct direction.

Yes, Intel graphic cards are really bad when it comes to OpenGL specifications compatibility... But newer drivers tend to be better with time ;)
