#include <CGAL/Three/Buffer_objects.h>

Definition

The Vao struct is a wrapper for the QOpenGLVertexArrayObject.

They are context dependent, most of the time it means Viewer dependent.

Constructor & Destructor Documentation

Vao() [1/2]

CGAL::Three::Vao::Vao

(

QOpenGLShaderProgram *

program

)

Creates a Vao.

Parameters

program

the QOpenGLShaderProgram associated with this Vao.

Attention

This must be called within a valid OpenGLContext. Most of the time, initGL() functions are safe places to do so.

Vao() [2/2]

CGAL::Three::Vao::Vao	(	Vao *	vao,
		QOpenGLShaderProgram *	program
	)

Creates a Vao from another one.

Parameters

program	the QOpenGLShaderProgram corresponding to the one of vao but from the right viewer.
vao	the Vao to copy.

All vao's vbos will be shared. Use it for shared viewers. initializeBuffers() will have to be called again.

Attention

This must be called within a valid OpenGLContext. Most of the time, initGL() functions are safe places to do so.
