# OpenXR Render models demo
|
|
|
|
This is a demo showing OpenXR's render models implementation.
|
|
|
|
Language: GDScript
|
|
|
|
Renderer: Compatibility
|

|
> This demo requires Godot 4.5 or later

## How does it work?
|
|
|
|
OpenXR allows us to run our application without having knowledge of the hardware being used,
|
|
or that we as developers have access too at the time of developing our application.
|
|
|
|
As a result we don't have direct information telling us what hardware is being used,
|
|
however there are situations where we want to visually show this hardware.
|
|
|
|
This specifically applies to the controllers used by the user, as showing the correct hardware
|
|
improves the user's sense of immersion.
|
|
|
|
The render model API allows us to enumerate the devices currently in use and then query
|
|
information such as its 3D asset, its position and orientation in space, and the position
|
|
and orientation of individual components of the asset.
|
|
|
|
Godot's implementation hides most of the complexity of this through the OpenXRRenderModelManager
|
|
node as a child of the XROrigin3D node. You can add just this node by itself and let it show
|
|
all render models that are currently active, or like we do in this demo, you can add nodes
|
|
in the tree of each controller to show render models related to that controller.
|
|
|
|
## Action map
|
|
|
|
This demo project has a barebones action map as we're only dealing with positioning.
|
|
|
|
## Running on PCVR
|
|
|
|
This project can be run as normal for PCVR. Ensure that an OpenXR runtime has been installed.
|
|
|
|
## Running on standalone VR
|
|
|
|
You must install the Android build templates and OpenXR loader plugin and configure an export template for your device.
|
|
Please follow [the instructions for deploying on Android in the manual](https://docs.godotengine.org/en/stable/tutorials/xr/deploying_to_android.html).
