kandi X-RAY | dead-reckoning Summary
Here we implement a simple navigation algorithm using yaw attitude data obtained from a smartphone. We compare our estimated trajectory with GPS. Requires numpy and imageio.

QUESTION
Let's say I had a wireframe, 3D object such as https://free3d.com/3d-model/freerealsichand-85561.html
Let's say I wanted to fix the wrist of said object to be the readout of an accelerometer wrist watch (e.g., get position via dead-reckoning).
How can I plot a 3-D image like this in rgl
?
How can I rotate / translate said image based on changes to accelerometer data?
Bonus for: how can I play an animation
of this activity. (e.g., library animation
)
The accelerometer is 3-DOF: x-acc, y-acc, z-acc without any other data.
...ANSWER
Answered 2017-Oct-08 at 11:29That link includes the hand in several formats, but rgl
can't currently read them. It comes closest with the .OBJ format, but can't read the normals or textures that are recorded in that file, so it fails. You might want to try updating readOBJ
to support more of the OBJ format; alternatively, you can remove that information like this:

Install dead-reckoning
You can use dead-reckoning like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
