Point cloud (3d scan)

Hi all,

I am a beginner with processing and programming in general, so patience:)

I come from an architecture background. At the moment I am doing a project that involves 3d scanning. So, in some future what I would like to achieve with processing is to load a scan, render out point clouds and manipulate it interactively.

Right now, I am trying to work out the first step, to load my scan into Processing. Originally scanned with Faro scanner, further manipulated in Pointools. So, my output files could be .psi .pst .pod .xyz a few others. Are the libraries that would allow me to load this data and how would I then go about rendering it?

I know those are very generalised questions and I am doing a lot digging around the net, but at the moment struggle to get on the right path, so any help would be appreciated!

Hi, are you still trying to get Faro data into processing?

if you can get your file into an .obj file then you can use this:

unfortunately I was not able to find a utility to convert the files you listed, however, if you can get your file to one of the files in the list below, then you can use the accompanying 3d converter.

Thanks for the input Benj, I have now found a way to get the point clouds in xyz arrays as a text file into processing by looking at the Radiohead House of Cards code by Aaron Koblin here https://code.google.com/p/radiohead/downloads/list

Looks promising so far. I think conversion to obj might be problematic as normally Lidar scan datasets are in the 10's of millions of points range, which might be too mch for obj to deal with, especially as each point can have a unique rgb value also.
