Destructor.
GLVertexBuffer(int numElements, int numVertices)
Constructor.
GLuint BindVBO(void *deviceContext=NULL)
Returns the GL buffer object.
void UpdateData(const float *src, int startVertex, int numVertices, void *deviceContext=NULL)
int GetNumVertices() const
Returns how many vertices allocated in this vertex buffer.
static GLVertexBuffer * Create(int numElements, int numVertices, void *deviceContext=NULL)
Creator. Returns NULL if error.
int GetNumElements() const
Returns how many elements defined in this vertex buffer.
Concrete vertex buffer class for GLSL subdivision and OpenGL drawing.
