Launch the .app then listen to the port 32000.
When a blob is tracked, an OSC message is sent on /blob, with the following data structure :
| position | datatype | description |
|---|---|---|
| 0 | int |
blob.ID |
| 1 | String |
blob.color_name |
| 2 | int |
blob.polygon.npoints |
3 to npoints |
float |
blob.polygon.xpoints[] |
npoints + 4 to npoints * 2 + 4 |
float |
blob.polygon.ypoints[] |
When a blob is lost, an OSC message is sent on /remove with the following data structure :
| position | datatype | description |
|---|---|---|
| 0 | int |
blob.ID |
In order to consolidate serv/client syncing, an OSC message is sent every X millis (see class_oscWrapper:26) on /consolidate with the following data structure :
| position | datatype | description |
|---|---|---|
| 0 | int |
blobs.length |
1 to blobs.length |
int |
blobs_id[] |
