Thanks. Out of interest, how are you going to be using this?

[Remi-C]

In postgres data server (SGBD), you can create function written in python (using CREATE LANGAGE PLPYTHONU).
This kind of server can be hacked into a Point Cloud server using PostGis and an extension called pointcloud.
The work is here and here

It give a talk in September to present how to use this :

• basics
  • load billions of points
  • fast retrieval
  • fast filtering
• processing
  • convert points to image (raster)
    • in base image processing for detection in pointcloud (sidewalk, buildings)
  • in base point cloud processing for
    • plane detection (using pcl)
    • structural vector detection (using scilearn and ICA)
    • automatic clustering (pcl+scilearn).
• visualization
  • interactive exploration of massiv point cloud in browser.
  • Interactive pointcloud algorithm control in browser.

I like this python-pcl, I hope more cool stuff will be added to it !

For the clustering I use the DBScan algorithm, and it would give better result with normals

It is not compiling,
damn!

Please tell me you didn't submit a pull request without even checking it
compiled.

I don't understand I just redid the stuff I had did on the branch, which was compiling...
something about the "at" operator.
pcl/_pcl.pyx:321:33: Object of type 'PointNormalCloud_t' has no attribute 'at'
Trying to understand, I'm no dev, and my firtst python module was 2 days ago..

[Remi-C]

Ok I found it :
200dae6
In this commit,
the at operator was removed.
I don't understand why , so I don't know what to do?
Cheers,

Ok,
Fresh new pull request here
changed everything so now it can compile.
You'll have to test it, for the moment pcl is no more working on my computer.

Cheers,
