Collaboration diagram for ngl::SimpleVAO:

Public Member Functions
virtual void	draw () const
	draw the VAO using glDrawArrays More...

virtual	~SimpleVAO ()
	dtor clears the VAO data More...

virtual void	removeVAO ()
	remove the VAO and buffers created More...

virtual void	setData (const VertexData &_data)
	, this method sets the data for the VAO if data has already been set it will remove the existing data and then re-set with the new data. More...

GLuint	getBufferID (unsigned int)
	return the id of the buffer, if there is only 1 buffer just return this if we have the more than one buffer the sub class manages the id's More...

Public Member Functions inherited from ngl::AbstractVAO
virtual	~AbstractVAO ()=default
	dtor usually this will not be called More...

void	bind ()
	bind the VAO so it can be used. More...

void	unbind ()
	unbind the VAO by binding default 0 More...

void	setVertexAttributePointer (GLuint _id, GLint _size, GLenum _type, GLsizei _stride, unsigned int _dataOffset, bool _normalise=false)
	set the generic vertex attribute pointer data usually this method will do however the user may occasionally need to override this method. More...

void	setNumIndices (size_t _s)
	the number of indices to draw in the array. It may be that the draw routine can overide this at another time. More...

GLenum	getMode () const
	get the draw mode More...

void	setMode (const GLenum &_mode)
	set the draw mode More...

Static Public Member Functions
static AbstractVAO *	create (GLenum _mode=GL_TRIANGLES)
	creator method for the factory More...

Protected Member Functions
	SimpleVAO (GLenum _mode)
	ctor calles parent ctor to allocate vao; More...

Protected Member Functions inherited from ngl::AbstractVAO
	AbstractVAO (GLenum _mode=GL_TRIANGLES)

Private Attributes
GLuint	m_buffer =0
	the id of the buffer for the VAO More...

Additional Inherited Members
Protected Attributes inherited from ngl::AbstractVAO
GLenum	m_mode =GL_TRIANGLES
	the draw mode More...

GLuint	m_id =0
	the id of the VAO allocated from OpenGL More...

bool	m_bound =false
	debug flag to indicate if the vao is bound. More...

bool	m_allocated =false
	debug flag to indicate if data has been set for the VAO More...
