## Detailed Description

Concrete vertex buffer class for CPU subdivision.

CpuVertexBuffer implements the VertexBufferInterface. An instance of this buffer class can be passed to CpuEvaluator

Definition at line 42 of file cpuVertexBuffer.h.

## Constructor & Destructor Documentation

## ◆ ~CpuVertexBuffer()

~CpuVertexBuffer | ( |  | ) |

Destructor.

## ◆ CpuVertexBuffer()

CpuVertexBuffer | ( | int | numElements,
|  | int | numVertices )
| protected

Constructor.

## Member Function Documentation

## ◆ BindCpuBuffer()

float * BindCpuBuffer | ( |  | ) |

Returns the address of CPU buffer.

## ◆ Create()

CpuVertexBuffer * Create | ( | int | numElements,
|  | int | numVertices,
|  | void * | deviceContext = NULL )
| static

Creator. Returns NULL if error.

## ◆ GetNumElements()

int GetNumElements | ( |  | ) | const

Returns how many elements defined in this vertex buffer.

## ◆ GetNumVertices()

int GetNumVertices | ( |  | ) | const

Returns how many vertices allocated in this vertex buffer.

## ◆ UpdateData()

void UpdateData | ( | const float * | src,
|  | int | startVertex,
|  | int | numVertices,
|  | void * | deviceContext = NULL )

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