I was doing an OpenGL display, where I render in an opengl context (GLUT).

But now I would like to integrate it into a big project that does not use the Qt OpenGL API at all (QGLWidget, QOpenGLWidget, …).

So I would have to display on QWidget for example using the function glTexImage2D () because it can take a Qimage input ((GLvoid *) Qimage.bits ())

  • \$\begingroup\$ Ok but wath is the difference with a PBO. Usualy I use a buffer like this : GLuint pboIds[2] \$\endgroup\$ Commented Jul 22, 2019 at 8:12
  • \$\begingroup\$ and with a PBO I already do that the probleme is to link a texture with a qt window I think \$\endgroup\$ Commented Jul 22, 2019 at 9:02
