Detailed Description

Concrete vertex buffer class for OpenCL subdivision.

CLVertexBuffer implements CLVertexBufferInterface. An instance of this buffer class can be passed to CLEvaluator

Definition at line 42 of file clVertexBuffer.h.

Constructor & Destructor Documentation

~CLVertexBuffer

(

)

Destructor.

CLVertexBuffer ( int  numElements, int  numVertices, cl_context  clContext  )

protected

Constructor.

Member Function Documentation

bool allocate ( cl_context  clContext )

protected

Allocates CL memory for this buffer. Returns true if success.

cl_mem BindCLBuffer

(

cl_command_queue

queue

)

Returns the CL memory object.

static CLVertexBuffer* Create ( int  numElements, int  numVertices, cl_context  clContext  )

static

Creator. Returns NULL if error.

static CLVertexBuffer* Create ( int  numElements, int  numVertices, DEVICE_CONTEXT  context  )

int GetNumElements

(

)

const

Returns how many elements defined in this vertex buffer.

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,
		cl_event *	startEvents = NULL,
		unsigned int	numStartEvents = 0,
		cl_event *	endEvent = NULL
	)

This method is meant to be used in client code in order to provide coarse vertices data to Osd.

void UpdateData ( const float *  src, int  startVertex, int  numVertices, DEVICE_CONTEXT  context, cl_event *  startEvents = NULL, unsigned int  numStartEvents = 0, cl_event *  endEvent = NULL  )
