C Specification

The xrGetRenderModelPropertiesFB function is defined as:

// Provided by XR_FB_render_model
XrResult xrGetRenderModelPropertiesFB(
    XrSession                                   session,
    XrPath                                      path,
    XrRenderModelPropertiesFB*                  properties);

Parameters

Parameter Descriptions

  • session is the specified XrSession.

  • path is the path of the render model to get the properties for.

  • properties is a pointer to the XrRenderModelPropertiesFB to write the render model information to.

Description

xrGetRenderModelPropertiesFB is used for getting information for a render model using a path retrieved from xrEnumerateRenderModelPathsFB. The information returned will be for the connected device that corresponds to the path given. For example, using /model_fb/controller/left will return information for the left controller that is currently connected and will change if a different device that also represents a left controller is connected.

The runtime must return XR_ERROR_CALL_ORDER_INVALID if xrGetRenderModelPropertiesFB is called with render model paths before calling xrEnumerateRenderModelPathsFB. The runtime must return XR_ERROR_PATH_INVALID if a path not given by xrEnumerateRenderModelPathsFB is used.

If xrGetRenderModelPropertiesFB returns a success code of XR_RENDER_MODEL_UNAVAILABLE_FB and has a XrRenderModelPropertiesFB::modelKey of XR_NULL_RENDER_MODEL_KEY_FB, this indicates that the model for the device is unavailable. The application may keep calling xrGetRenderModelPropertiesFB because the model may become available later when a device is connected.
