C Specification

The xrTriangleMeshGetVertexBufferFB function is defined as:

XrResult xrTriangleMeshGetVertexBufferFB(
    XrTriangleMeshFB                            mesh,
    XrVector3f**                                outVertexBuffer);

Parameters

Parameter Descriptions
  • mesh is the XrTriangleMeshFB to get the vertex buffer for.

  • outVertexBuffer is a pointer to return the vertex buffer into.

Description

Retrieves a pointer to the vertex buffer. The vertex buffer is structured as an array of XrVector3f. The size of the buffer is vertexCount. The application must call xrTriangleMeshBeginUpdateFB or xrTriangleMeshBeginVertexBufferUpdateFB before making modifications to the vertex buffer. The buffer location is guaranteed to remain constant over the lifecycle of the mesh object.
