Export rotations, and world position of joints to CSV files respectively.

ValueError: Changing the dtype to a subarray type is only supported if the total itemsize is unchanged

line 59, in get_hierarchy_data
offsets = rec_array[['offsetx', 'offsety', 'offsetz']].copy().view((float, 3))

The conversion is walking the BVH tree for each frame. But the file already has all the rotation values and it just needs to be filtered.

Maybe the values still need conversion because of rotation order or something else. Should check.
There's definitely much room for performance impovement.

write() raise Error while it write _get_hierarchy_string(). The error is
IndexError: key CHANNELS not found
The error occur when it try to access the child with End Site, which should have no CHANNELS property.

How to actually use the bvh2csv (and csv2bvh) script? Trying to launch it, but getting the error of no module named 'numpy' Numpy installed, actually.

Should I install the bvh-toolbox first somehow? Also, getting error running setup.py - error in bvhtoolbox setup command: ('Duplicate entry point', 'console_scripts', 'bvh2egg')

I got some Position and rotation data from Azure Kinect. I have converted Azure Kinect Quaternion data to Euler angles and I have set up my hierarchy according to Microsoft documentation. However, after converting my position and orientation data to bvh, no motion is shown when I played the bvh file.

FIles are attached.

Which tool (if any in particular)
I was using the csv2bvh tool. I am on MacOS. I am using Python 3.8.

Describe the bug
The bug causes this error:

Exception: ERROR: No rotation data found for: 

To Reproduce
Steps to reproduce the behavior:

1. Run command
   csv2bvh hierarchy.csv position.csv rotation.csv

Expected behavior
The files convert into a BHV file

Additional context
Here are are the CSV files I am using:
https://drive.google.com/drive/folders/1lTKWIRG16m5JfHO52vjNKG1WYOvyFlFr?usp=sharing

When the list of file names is empty, the batch script tries to create 0 pools and throws an exception.

Only create the overhead of creating pools, when there are at least 2 files.
Give feedback when no files were given.

d04b3bc introduced a new issue. It's encountering a PicklingError when multiple files shall be batch converted. At least on Windows. Check on Linux, as it is not likely to occur there, because of using fork instead of spawn for processes.

For an explanation see, for example, https://stackoverflow.com/a/9336868.

Needs more tests. Also test the shell commands.

RuntimeWarning: 'bvhtoolbox.convert.bvh2csv' found in sys.modules after import of package 'bvhtoolbox.convert', but prior to execution of 'bvhtoolbox.convert.bvh2csv'; this may result in unpredictable behaviour
warn(RuntimeWarning(msg))

Any possibility of adding an example or more documentation for renaming joints?

I see:

for row in csv_reader:
mapping[row[0]] = row[1]

But no matter what I'm getting: NameError: name 'mapping' is not defined.

Thank you!

Is it posible to convert csv back to bvh? Do you have existing functional for that?

limits the length of the joint names to 20, but in tests, you have joint names which are much longer, creating artifacts in the csvs such as:

mixamorig:LeftHandMi,mixamorig:LeftHandMi, 3.60930, -0.16690, 0.07780
mixamorig:LeftHandMi,mixamorig:LeftHandMi, 3.40040, -0.62740, 0.11480
mixamorig:LeftHandMi,mixamorig:LeftHandMi, 3.62050, -0.64930, 0.11990

Maybe adding an invertibility test (bvh -> csv -> bvh) would be of value? This could be part of #11

Additional context
Add any other context about the problem here.

I installed the new Numpy Lib while processing with bvh.

numpy version = 1.26.4

I could see that the numpy version of bvhtoolbox was low.

If anyone is experiencing this problem, this error will not occur if you use numpy version 1.20 or lower.

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
