This thread is basically asking the same thing as me.

I'm using Cinder/OF with MS Kinect to develop an Application for performance art purposes and the data is in point cloud.

I've never worked with Houdini before but worked with programs like Maya, Unity, etc.

How do I import this point cloud data into Houdini to manipulate the pixels/point cloud?

I read the above thread but I'm not sure how to save a Cinder project as a .ply or PC format.

Any tutorials/information on how to accomplish this would be greatly appreciated.

Thanks!

Loop through all your points and write out to the file IN the .ply ASCII format. Here's a description of the format:

I've also attached an example .ply point cloud file that you can use as a template. (I had to zip it up for it to attach)

Thanks. I took a look at the file and was successfully able to import it into it by making a video and then turning it into an obj sequence and importing that.

Anyways,

This lady in this video is doing a fabulous job and is using Houdini.

Since I'm new to Houdini I'd like to be able to manipulate pixels of the kinect like she did. Anyone know how she's doing this?

How to start on this? I'm currently exploring myself but If I can get an answer it would be great.

Also although she's using Houdini, she seems to be using another program that I can't currently make out. Anyone know what it is?

I've imported my OBJ sequence but it's not in point cloud it's in a more of mesh form.

Thanks!

You can just delete all the primitives by appending an Add SOP and toggle on Delete Geometry but Keep Points.
