Detailed Description

Concrete vertex buffer class for GLSL subvision and OpenGL drawing.

GLVertexBuffer implements GLVertexBufferInterface. An instance of this buffer class can be passed to OsdGLComputeEvaluator.

Definition at line 44 of file glVertexBuffer.h.

Constructor & Destructor Documentation

~GLVertexBuffer ( )

Destructor.

protected

Constructor.

bool allocate ( )

protected

Allocates VBO for this buffer. Returns true if success.

GLuint BindVBO ( void * deviceContext = NULL )

Returns the GL buffer object.

static GLVertexBuffer* 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.
