Parameter Descriptions

Description

Signals to the runtime that the application has finished updating the vertex buffer data following a call to xrTriangleMeshBeginVertexBufferUpdateFB.

The triangle mesh mesh must be mutable. The runtime must return XR_ERROR_VALIDATION_FAILURE if the mesh is immutable.

The triangle mesh mesh must be in state https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#fb_triangle_mesh_state_updating_vertices.

A successful call moves mesh to state https://registry.khronos.org/OpenXR/specs/1.1/html/xrspec.html#fb_triangle_mesh_state_ready.
