int GetNumElements() const
Returns how many elements defined in this vertex buffer.
Concrete vertex buffer class for OpenCL subvision.
cl_mem BindCLBuffer(cl_command_queue queue)
Returns the CL memory object.
CLVertexBuffer(int numElements, int numVertices, cl_context clContext)
Constructor.
int GetNumVertices() const
Returns how many vertices allocated in this vertex buffer.
void UpdateData(const float *src, int startVertex, int numVertices, cl_command_queue clQueue)
static CLVertexBuffer * Create(int numElements, int numVertices, cl_context clContext)
Creator. Returns NULL if error.
