#include <cpuGLVertexBuffer.h>
Concrete vertex buffer class for cpu subvision and OpenGL drawing.
CpuGLVertexBuffer implements CpuVertexBufferInterface and GLVertexBufferInterface.
The buffer interop between Cpu and GL is handled automatically when a client calls BindCpuBuffer and BindVBO methods.

§ ~CpuGLVertexBuffer()
§ CpuGLVertexBuffer()
§ allocate()
Allocates VBO for this buffer. Returns true if success.
§ BindCpuBuffer()
Returns cpu memory. GL buffer will be mapped to cpu address if necessary.
§ BindVBO()
GLuint BindVBO |
( |
void * |
deviceContext = NULL | ) |
|
Returns the name of GL buffer object. If the buffer is mapped to cpu address, it will be unmapped back to GL.
§ Create()
static CpuGLVertexBuffer* 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.
