Re: Point Clouds Comparison

Indeed, if you are only interested in rotation and/or translation, it will be faster (and much robust to noise) to directly use the planes equations. Otherwise, if there's non-rigid transformation at stake, the cloud-plane distances will be more valuable. Of course, you can do both (at least to asse...

Re: Signed Cloud/Cloud distance using Normals

Ah, have you met Dimitri recently?! No, it's a joke, but Dimitri Lague (from Rennes University) has made several attempts of convincing me to add such an option to CloudCompare in the past. We had a lot of discussions about this (but I realized now that it was mostly by email, and not on the forum)....

Re: Point Clouds Comparison

I won't go so far as to say that it's "the best method" for your problem: I don't know your problem ;) It all depends on what you really want to determine: [*] if you want to evaluate a bending or any similar global deformation, then yes [*] if you want to evaluate a global translation and...

Re: Point Clouds Comparison

Indeed, the extent of the plane must be larger than the cloud's one. In this comparison mode, CloudCompare only considers the triangles that compose the "plane" (the plane here is a triangular mesh, as any other CloudCompare meh). Then it computes the distance from every point to the neare...

Re: Point Clouds Comparison

The main difference here is scale. In the cloud-to-cloud distance with local modeling, small LS planes are computed locally around each point (in a very small neighborhood, which size is controlled by a hidden parameter). Therefore, they are much more prone to local noise and their orientations may ...

Re: On accessibility of CC by plugins, and other questions

Hello Luca, 1. For standard plugins, there's a 'uiModificationFlags' as output variable (second parameter of 'doAction'). You can set the 'CC_PLUGIN_REFRESH_ENTITY_BROWSER' bit flag to make CC do what you want on plugin completion. uiModificationFlags |= CC_PLUGIN_REFRESH_ENTITY_BROWSER; Look to qPo...

Re: Linking errors when building in Debug

No you're right! By starting from a clean version freshly downloaded from the SVN server, I reproduced the error (with an older version of Qt). I don't know yet how I managed to get a working version until know, but for the moment I remove the 'Multi-thread' support in debug mode (it works fine in r...

Re: PCL library and binary format

Great work! As soon as you tell me, I'll add the plugin to the main trunk (or even better, I'll let yourself push it in with a personalized account - so you'll be able to do some maintenance ;). It will be also easier for me to do minor corrections (if necessary). For CMake, let's wait a little bit ...

Re: CloudCompare standalone viewer

Indeed, this is still in the "TODO" list. It shouldn't be very hard to do, the only thing that will need some time is to define precisely what should be handled by this new format (clouds and/or meshes? options such as points size, even maybe the camera settings? etc.). There will be two v...
