GLViewWidget
(parent=None)[source]¶ - Basic widget for displaying 3D data
- Rotation/scale controls
- Axis/grid display
- Export options
-
cameraPosition
()[source]¶ Return current position of camera based on center, dist, elevation, and azimuth
-
itemsAt
(region=None)[source]¶ Return a list of the items displayed in the region (x, y, w, h) relative to the widget.
-
orbit
(azim, elev)[source]¶ Orbits the camera around the center position. azim and elev are given in degrees.
-
paintGL
(region=None, viewport=None, useItemNames=False)[source]¶ 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)[source]¶ 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)[source]¶ Return the approximate size of a screen pixel at the location pos Pos may be a Vector or an (N,3) array of locations
