## Detailed Description

Concrete vertex buffer class for Cuda subdivision.

CudaVertexBuffer implements CudaVertexBufferInterface. An instance of this buffer class can be passed to CudaEvaluator

Definition at line 25 of file cudaVertexBuffer.h.

## Constructor & Destructor Documentation

## ◆ ~CudaVertexBuffer()

~CudaVertexBuffer | ( |  | ) |

Destructor.

## ◆ CudaVertexBuffer()

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

Constructor.

## Member Function Documentation

## ◆ allocate()

bool allocate | ( |  | ) |
| protected

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

## ◆ BindCudaBuffer()

float * BindCudaBuffer | ( |  | ) |

Returns cuda memory.

## ◆ Create()

CudaVertexBuffer * 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.
