CloudCompare forum

It wasn't a radius problem. I was using a value very close to the default value in the program's dialog. The problem with the octree levels was due to a bug in my reading of the cloud.

Sorry about that!

Sorry, I missed the build line I copied my code into the previous post. I do it right before the geometric analysis but it doesn't seem to have any effect.

Yes, I was running in Debug and it looks like I wasn't being patient enough :)

Now it works but, even in Release , I think its slower than it should be. Calculating the same feature in the CloudCompare program is faster and the 'Octree level', 'Cells' and 'Max population' values are much lower ...

Hi everyone,

I'm having trouble using the GeometricalAnalysisTools inside my own class.

In the code below, mCloud is a succesfully read ccPointCloud, but when the program enters the ComputeCharactersitic function it never leaves it.


void CCGeometricAnalizer::compute()
{
//create SF
int idx ...

Hello,

That was it! At one point I started passing the position as an absolute value and not as a relative one.

Thanks for all the answers and thanks also for this great software and code!!

Have a nice week!

The setDisplayedIn2D(true) method didn't make any change.

With a derived class to access the protected members, I have also tried setting the m_showFullBody boolean to true and using the drawMeOnly2D() method, but I always get the same result.

Hello Daniel! Thanks for your reply.

I'm not using my algorithms directly on the cloud so I think I don't know the point index, just the position.

However, I have made a workaround where we have two clouds: one with the points we analyze and one auxiliary just to display labels.

My function look ...

Hi everyone!

I want to use CCLib to display labels at certain points on my cloud. I want to achieve something similar to what happens when you use the Point picking tool.

As far as I know, the functions related to display labels are connected to the point picking process but I ...

comp_example is a ccHObject instance (a 'group' object). You cannot convert it to a point cloud directly.

You have to look for its children (normally there should only be one if you load an ASCII file) and this child should be a point cloud. Pay attention that ccHObjectCaster::ToPointCloud may ...

Hello everyone!

I'm trying to implement the "Compute cloud/cloud distance" in a Qt project. I have been able to run the ccViewer in Qt. and, also, I'm capable of visualize clouds dropped on the viewer window or from a file read in the code.

My main problem is that, when I compute the distances, I ...
