Description:

virtualreality 0.1.2

virtualreality
python side of hobo_vr
mainly used for writing posers
has many helpful utilities for positional tracking, serial/socket/bluetooth communication, etc.
has an async socket server
installation
to install the module, run the following command:
python -m pip install virtualreality

if you want to have camera based tracking, install it with the camera extra
python -m pip install virtualreality[camera]

to install the development version, do the following:
git clone https://github.com/okawo80085/hobo_vr
cd ./hobo_vr
python -m pip install -e .

udu poser client example
u - unlimited
d - devices
u - upgrade

buts its more like a mode
here is an example

# this dictates devices used
# for this example its:

unlike normal posers, udu posers generate pose structs on start
you then need use those pose structs as the value for DeviceManifestList in the driver config
more info on udu
more examples
hobo_vr's examples
there is also poser_3dof_hmd_only.py, its an udu poser with actual 3dof(hmd only) tracking(more info in the example itself)
