Plot3DWidget: OpenGL scene widget

This module provides a Qt widget embedding an OpenGL scene.

Plot3DWidget

class Plot3DWidget(parent=None, f=<PyQt5.QtCore.Qt.WindowFlags object>)[source]

Bases: silx.gui._glutils.OpenGLWidget.OpenGLWidget

OpenGL widget with a 3D viewport and an overview.

sigInteractiveModeChanged

Signal emitted when the interactive mode has changed

sigStyleChanged

Signal emitted when the style of the scene has changed

It provides the updated property.

setInteractiveMode(mode)[source]

Set the interactive mode.

Parameters:mode (str) – The interactive mode: ‘rotate’, ‘pan’ or None
getInteractiveMode()[source]

Returns the interactive mode in use.

Return type:str
setProjection(projection)[source]

Change the projection in use.

Parameters:projection (str) – In ‘perspective’, ‘orthographic’.
getProjection()[source]

Return the current camera projection mode as a str.

See setProjection()

setBackgroundColor(color)[source]

Set the background color of the OpenGL view.

Parameters:color (QColor, str or array-like of 3 or 4 float in [0., 1.] or uint8) – RGB color of the isosurface: name, #RRGGBB or RGB values
