- WebXR API polyfill
- Multiple XR devices emulation
- Both VR and AR support
- Graphical device emulator control with Three.js
- Cross browsers support with WebExtensions API
- Based on WebXR device API draft issued on 10 October 2019
- No device specific emulation yet
- Supports only trigger and squeeze buttons, not other buttons
This extension is built on top of WebExtensions API. It works on Firefox, Chrome, and other browsers supporting the API.
-
Go to WebXR application page (for example WebXR examples). You will notice that the application detects that you have a XR device (emulated) and it will let you enter the immersive (VR、AR) mode.
-
Open "WebXR" tab in the browser developer tool (Firefox, Chrome) to controll the emulated devices. You can move the headset and controllers, and trigger the controller buttons. You will see their transforms reflected in the WebXR application.
By clicking a device in the devtool panel, you can select gizmo mode of the device. By dragging a gizmo, you can rotate or translate the device.
You can configure some settings from the top in the WebXR tab.
You can switch emulated device. The difference between devices is just degrees of freedom and the number of controllers for now.
| Device | Description |
|---|---|
| None | No device |
| Google Cardboard | 3dof headset and no controller |
| HTC Vive | 6dof headset and two 6dof controllers |
| Oculus Go | 3dof headset and 3dof controller |
| Oculus Quest | 6dof headset and two 6dof controllers |
| Samsung Gear VR | 3dof headset and 3dof controller |
You can enable/disable Stereo Effect which renders two views.
WebXR emulator extension also supports AR. You can test WebXR AR application on an emulated device in a virtual room, on your desktop browser.
