# GLViewWidget

class `pyqtgraph.opengl.``GLViewWidget`(parent=None)
  Basic widget for displaying 3D data
    - Rotation/scale controls
    - Axis/grid display
    - Export options
  `__init__`(parent=None)
  `cameraPosition`()

    Return current position of camera based on center, dist, elevation, and azimuth

  `itemsAt`(region=None)

    Return a list of the items displayed in the region (x, y, w, h) relative to the widget.

  `orbit`(azim, elev)

    Orbits the camera around the center position. azim and elev are given in degrees.

  `paintGL`(region=None, viewport=None, useItemNames=False)

    viewport specifies the arguments to glViewport. If None, then we use self.opts[‘viewport’] region specifies the sub-region of self.opts[‘viewport’] that should be rendered. Note that we may use viewport != self.opts[‘viewport’] when exporting.

  `pan`(dx, dy, dz, relative=False)

    Moves the center (look-at) position while holding the camera in place.

    If relative=True, then the coordinates are interpreted such that x if in the global xy plane and points to the right side of the view, y is in the global xy plane and orthogonal to x, and z points in the global z direction. Distances are scaled roughly such that a value of 1.0 moves by one pixel on screen.

  `pixelSize`(pos)

    Return the approximate size of a screen pixel at the location pos Pos may be a Vector or an (N,3) array of locations

  `readQImage`()

    Read the current buffer pixels out as a QImage.

  `setBackgroundColor`(*args, **kwds)

    Set the background color of the widget. Accepts the same arguments as pg.mkColor() and pg.glColor().
