Detailed Description

Concrete vertex buffer class for cpu subdivision 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

~CpuGLVertexBuffer ( )

Destructor.

protected

Constructor.

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.

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