OpenVR support for Panda3D
Project description
panda3d-openvr
This module provides basic integration of OpenVR with Panda3D using pyopenvr
Requirements
This module requires Panda3D > 1.10, pyopenvr and a implementation of OpenVR (SteamVR or OpenComposite (not tested though...))
Installation
git clone https://github.com/el-dee/panda3d-openvr
cd panda3d-openvr
python3 setup.py install
Usage
To use panda3d-openvr, first import the p2dopenvr module in your application :
import p3dopenvr
Then, once an instance of ShowBase is created, instanciate the VR interface and initialize it :
myvr = P3DOpenVR()
myvr.init()
Once done, the module will enable the VR application layer of OpenVR, create the left and right cameras and configure the rendering system to send the images of each eye to the VR compositor.
Note that SteamVR must be already running before you launch your application.
You can create a derived class from P3DOpenVR to provide the implementation of the event handler or to manage the actions, see the samples below.
The module will create the following hierachy in the scenegraph :
- Traking space origin (tracking_space)
- HMD anchor (hmf_anchor)
- Left eye (left_eye_anchor)
- Right eye (right_eye_anchor)
- Tracked device 1
- Tracked device 2
- ...
- HMD anchor (hmf_anchor)
By default the left eye image is also rendered on the main application window.
Examples
All the examples are found under samples/ directory, to launch them simply go to their directory and run:
python3 main.py
Minimal
In minimal you can find a minimal setup that will draw a Panda avatar in front of you, render cameras for each tracking station and a (ugly) cube where your controllers ought to be.
This example shows how to use the simple event and pose interfaces to retrieve the position of the various elements in the tracking space and the events triggered by the user.
Actions
In samples/actions, you can find a demo using action manifest to bind actions from the user to event in the application. This is more complex to set up than the event interface, but allows the end user to remap the actions
Ralph
In samples/ralph you can find a heavily modified version of the Roaming Ralph demo. In the version, you are Ralph and you can explore the space around you. Using the trackpad on the left controller, you can move forward and backward in the direction you're facing, or rotate the camera.
License
Some parts of the code are directly coming from pyopenvr examples, which are (c) pyopenvr author "cmbruns"
Ralph demo base is copied over from Panda3D source code.
