failed to cumpute octree on cloud

[Lucien]

I have a cloud of 28 million points. When I did the segmentation, it's paused and said not enough memory. Is the cloud too heavy for CC?
I can't neither subsample to reduce the volume of cloud.
What's the cause?

[daniel]

That's weird. CC (and the octree) can work with clouds up to several hundred millions (the known record is 1.1 billion).

Maybe the error is with the parameters? Or is it with the standard (scissors) tool?

[Lucien]

I tested with open source CC(2.6.3.1 32bits) and the installer version(2.6.2 64bits). I find the problem occurs just in the opensource version.

[daniel]

You mean the version you compiled yourself?

[Lucien]

Yes, I compiled CC 2.6.3.1 32bits. Is there a lot of difference with 64bits?

[daniel]

The 32 bits version is much more limited in terms of memory. Moreover it's not officially supported anymore ;)

I tried to compile CC2.7 with Visual studio 2015 cummunity (release 64bits).But I had a lot of errors.

[daniel]

There's at least two separate problems:

• there's a mismatch between the compiler and some dependencies (probably Qt). Make sure that Qt is compiled with Visual 2015 64 bits, and that you chose the same compiler in CMake.
  [*) there's a known issue with Visual 2015 (see http://www.danielgm.net/cc/forum/viewtopic.php?t=1835)

[Lucien]

Thanks.
It works well with VS2013
