C Specification

The xrCreateGeometryInstanceFB function is defined as:

// Provided by XR_FB_passthrough
XrResult xrCreateGeometryInstanceFB(
    XrSession                                   session,
    const XrGeometryInstanceCreateInfoFB*       createInfo,
    XrGeometryInstanceFB*                       outGeometryInstance);

Parameters

Parameter Descriptions

Description

Creates an XrGeometryInstanceFB handle. Geometry instance functionality requires XR_FB_triangle_mesh extension to be enabled. An XrGeometryInstanceFB connects a layer, a mesh, and a transformation, with the semantics that a specific mesh will be instantiated in a specific layer with a specific transformation. A mesh can be instantiated multiple times, in the same or in different layers.
