After reading many interesting articles on the web about Kinect and how people play with 3D depth sensing we discovered that we can get similar 3D effects by using VDMX and a Quartz Composer plug-in.
First of all you need to download VDMX. http://www.vidvox.net/
And have already Quartz Composer, which is a groundbreaking graphics development environment that you find in your developing tools in the CD that comes with your Mac.
The demo version is free but you will not be able to save your projects.
Quartz Composer shaping to sound and other generative experiments
I am now creating tutorials to guide you to this point, so you need to be a little patient.
In case you are not patient, there are plenty tutorials on the web and you can also take some time reading the references links at the bottom of this post.
Now that you have VDMX and Quartz Composer, you need to meet Mr. Bill Etra our guru ( thank you Mr. Etra ! )
and download a plug in called Rutt Etra here: http://v002.info/?page_id=19
ah, do not forget to donate !!
You then will obtain the same 3D effects that you will have by using a Kinect camera with some work and reading.
