C Specification

The xrTriangleMeshEndUpdateFB function is defined as:

XrResult xrTriangleMeshEndUpdateFB(
    XrTriangleMeshFB                            mesh,
    uint32_t                                    vertexCount,
    uint32_t                                    triangleCount);

Parameters

Parameter Descriptions
  • mesh is the XrTriangleMeshFB to update.

  • vertexCount is the vertex count after the update.

  • triangleCount is the triangle count after the update.

Description

Signals to the runtime that the application has finished updating the mesh buffers following a call to xrTriangleMeshBeginUpdateFB. vertexCount and triangleCount specify the actual number of primitives that make up the mesh after the update. They must be larger than zero but smaller or equal to the maximum counts defined at create time.
