This example shows how to visualize 3D point clouds with with yarp.js using the Three.js library (a wrapper for WebGL). (Demo suggested by Pattacini in issue #3).
To set up the demo, follow the setup instructions in here.
The application opens a port /yarpjs/3Dpoints:i where 3D points can be sent and visualized in the browser. You can write to this port by running the command
$> yarp write ... /yarpjs/3Dpoints:i
on a shell. You can then add new points to the scene visualized in the browser by sending a bottle with format
>> (x y z R G B size)
where x y z are the cartesian coordinates of the point, the R G B colour defaults to black, namely (0 0 0) and the point size defaults to 5 pixels.
You can send multiple points at the same time by concatenating bottles (e.g. (b1) (b2) ... (bn)). Try it out!
Run the shell command $> node examples/point_cloud/send_point_cloud.js from the directory where you cloned yarp.js. (Thanks to Seanfa for the point cloud data).
