Detailed Description

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.

Constructor & Destructor Documentation

Destructor.

CpuGLVertexBuffer ( int  numElements,
int  numVertices 
)
protected

Constructor.

Member Function Documentation

bool allocate ( )
protected

Allocates VBO for this buffer. Returns true if success.

float* BindCpuBuffer ( )

Returns cpu memory. GL buffer will be mapped to cpu address if necessary.

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.

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

Creator. Returns NULL if error.

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,
void *  deviceContext = NULL 
)

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