Display glut window on Qt widget / QWindow

I am trying to configure one of the samples bundled in the OptiX 3.0.1 SDK to display in a Qt Widget.

The sample currently renders to a glut window and makes use of glViewport. Is there a way that I can change the glut window to a Qt Widget or make the glut window display on a Qt widget?

The sample makes use of a vertex buffer object:

glBindBuffer(GL_PIXEL_UNPACK_BUFFER, vboId);

I have created a class that inherits from QWindow. Is it possible to use the vertex buffer object to render to the QWindow?

GLUT is just another (very spartanic) application framework. You can replace it completely with Qt and QGLWidget.

  • glutCreateWindow → creation of a QGLWidget instance
  • glutDisplayFunc & a display handler → reimplement QGLWidget::paintGL in a derived class
  • glutReshapeFunc & a resize handler → reimplement QGLWidget::resizeGL in a derived class
  • user input functions → reimplement the event methods of QWidget
