Hi,
I wanted to ask if they are any examples of how to make up an animation moving based on incoming orientation data that is sent via Bluetooth from a wearable sensor?
I tried to use pygame but it did not work? I checked scene but it looks like it is not the right one.
@ProgrammingGo, what kind of an animation are you planning? Some kind of s pointer? 2D or 3D?
Hi thank you for your feedback,
I want to depict a cube that is moving based on the incoming data from the wearable sensor. Maybe I could use Euler angles and Quaternions. I think it should be 3d. An example of something similar to that I want to do is this video: link text
@ProgrammingGo Is your problem only a problem of animation or also the incoming of the data in BT?
I know how to get the data, the problem is how to do the animation. Or what do you mean by problem with the data?
@ProgrammingGo ok, just to be sure that you know how to get the data in BT because, for this, I can't help you.
In a few hours, I'll send something to test...
Okay thank you soo much! Could I display human body as well?
@ProgrammingGo wooo,wooo, one thing at a time. If you want to display a body, do you have a lot of IMU sensors, for instance one for each finger? 😀
@ProgrammingGo, check this thread and the linked github repo for a SceneKit wrapper with lots of samples.
Mr @pulbrich can surely help you get going with it.
@ProgrammingGo sorry, not a lot free time now, please, try this

Hi guys, thank you soo much for your support. I need some time to go through the code, because I want to understand it. Thank you soo much and don't worry @cvp it is perfectly okay.

@cvp Hi cvp thank you soo much. I will give a look on that. Thank you for your time. If I will have questions I will write here. I am thinking that it would be better to use quaternions instead of euler angler to avoid gimbal lock. I think there should be a lib for that, right?
@ProgrammingGo said:
I think there should be a lib for that
I suppose but I really don't know anything about that.
okay, I will give a trial. What for me is unclear is how I can map the sensor values to the graphic. I mean I know that I have a referential coordinate system and based on that my sensor is moving, but it is not clear how to do it.
@ProgrammingGo Euler angles are orientation data of your object (here a cube) versus the 3 axes, thus SceneKit geometry node is easy to orientate.
@cvp you don’t need a separate thread with all the overhead to update the scene objects. There is the scene renderer delegate (can be the same class instance as your main), which has an 'update' method to take care of exactly these type of tasks.
@pulbrich Thanks, the thread was for the Bluetooth listening, here simulated
@ProgrammingGo if you ever need to penetrate the domain of various coordinate system representations (angles included) I recommend you look at Pyrr
What would be cool would be to have two Pythonista scripts.
1. The iPhone script would get the pitch, yaw, and roll of the iPhone and transmit that over Bluetooth.
2. The iPad script could use those Bluetooth signals to change the angel of the airplane on the iPad screen.
@ccc getting the data is easy.
But I don't know anything about the Bluetooth part transmit/receive
http://omz-software.com/pythonista/docs/ios/cb.html
@ccc yes, I know and understand but I don't have any experience with it
@ccc, would suggest multipeer for that. Uses bluetooth without the need to think about it.

Pitch, yaw and roll of iDevice + AirPlane, but not Bluetooth, nor WiFi
You can turn the device and pinch/rotate the image
Dirty (more than usual, believe me) and (not so) quick, but for the fun

LOL... I read @mikael ‘s impressive multipeer this morning and then wrote the iPhone piece of the two iOS device idea that I mentioned above. If you add multipeer to your code above, the angle (but perhaps not the angel) of the plane ✈️ on the iPad will react to iPhone movements.
https://github.com/cclauss/Ten-lines-or-less/blob/master/attitude_to_multipeer.py
@ccc Did you try my script on only one iDevice , it reacts to its movements.
I always only work on my iPad because my iPhone is very old and slow (iPhone 5s) but if you want, I could spend some time tomorrow to try what you say.
@ccc Done, thanks to marvelous multipeer of @mikael.
I use your attitude_to_multipeer.py on my iPhone and my script modified to get infos from iPhone on my iPad, source here
It’s great how community supports Pythonista live.
@cvp, @ccc, ah, this begs for a dogfight game — two controller iPhones and an iPad mirrored to Apple TV.
@mikael wooow, a full game is a too long work for me but I would be available to help with little parts
@adomanim, ”easy” might be a relative term here, but if you have a skeleton model, moving arms and legs could be accomplished with SceneKit and Inverse Kinematics constraints (and again, @pulbrich’s SceneKit wrapper).
