Hi there,

i have a question. i'm working with the kinect!

and i use shifmans detection mode called center of mass, but i it detects more than one user and i want that the kinect only works with one user, even if there a more of them in the room.

1. ////////// KINECT CENTER OF MASS /////////////
2.   image(kinect.depthImage(), 0, 0, 320, 240);
3.   kinect.update();
4.   IntVector userList = new IntVector();
5.   kinect.getUsers(userList);
6.   for (int i=0; i<userList.size(); i++) {
7.     int userId = userList.get(i);
8.     PVector position = new PVector();
9.     kinect.getCoM(userId, position);
10.     kinect.convertRealWorldToProjective(position, position);
11.  
12.   }
13. //////////////////////////////////

but if there is a better method than center of mass, please let me know :)

thank you a lot

Hello,

does somebody know if it is possible to modify the surface of a ellipsoid object from the shape 3d library - like an extrude nurb in cinema 4d?

thank you in advance!

markus

i have a problem! my sketch works fine, but if the kinect gets no data (NaN) the object will not appear / redrawn again - i think it has something to do with the userIds.
 
So how can i change that the kinect just to recognize 1 User and if hes gone she will keep the image  anyway

i hope you understand my bad english :/

thank you very much

1.  IntVector userList = new IntVector();
2.   kinect.getUsers(userList);
3.   for (int i=0; i<userList.size(); i++) {
4.     int userId = userList.get(i);
5.     PVector position = new PVector();
6.     kinect.getCoM(userId, position);
7.     kinect.convertRealWorldToProjective(position, position);
8.     fill(255, 0, 0);

Hi there,

Does someone have an idea? thank you
