GLViewWidget#
- class pyqtgraph.opengl.GLViewWidget(*args, devicePixelRatio=None, **kwargs)[source]#
Bases:
GLViewMixin
,QOpenGLWidget
- __init__(*args, devicePixelRatio=None, **kwargs)[source]#
- Basic widget for displaying 3D data
Rotation/scale controls
Axis/grid display
Export options
Arguments:
parent
(QObject, optional): Parent QObject. Defaults to None.
devicePixelRatio
No longer in use. High-DPI displays should automatically detect the correct resolution.
rotationMethod
(str): Mechanism to drive the rotation method, options are ‘euler’ and ‘quaternion’. Defaults to ‘euler’.
- cameraPosition()#
Return current position of camera based on center, dist, elevation, and azimuth
- clear()#
Remove all items from the scene.
- initializeGL()#
Initialize items that were not initialized during addItem().
- 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='global')#
Moves the center (look-at) position while holding the camera in place.
Arguments:
dx
Distance to pan in x direction
dy
Distance to pan in y direction
dz
Distance to pan in z direction
relative
String that determines the direction of dx,dy,dz. If “global”, then the global coordinate system is used. If “view”, then the z axis is aligned with the view direction, and x and y axes are in the plane of the view: +x points right, +y points up. If “view-upright”, then x is 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.
- removeItem(item)#
Remove the item from the scene.
- reset()#
Initialize the widget state or reset the current state to the original state.

Warning
The intention of this class is to provide users who want to use
QOpenGLWindow
instead ofQOpenGLWidget
but retain the benefits ofGLViewWidget
. Usage of this class should be considered experimental for the time being as it may change without warning in future releases.- Members:
