\brief Base type for 3D visualizations.
This type is the base type for all 3D visualizations in QtDataVisualization.
Note that this type is uncreatable, but contains properties that are shared between
the 3D visualizations.
For AbstractGraph3D enums, see \l QAbstract3DGraph::SelectionFlag and
\l QAbstract3DGraph::ShadowQuality
\sa Bars3D, Scatter3D, Surface3D, {Qt Data Visualization C++ Classes}
*/
/*!
\qmlproperty AbstractGraph3D.SelectionMode AbstractGraph3D::selectionMode
Active selection mode in the visualization.
*/
/*!
\qmlproperty AbstractGraph3D.ShadowQuality AbstractGraph3D::shadowQuality
Shadow quality.
*/
/*!
\qmlproperty bool AbstractGraph3D::shadowsSupported
This read-only property indicates if shadows are supported with the
current configuration or not. OpenGL ES2 configurations do not support shadows.
*/
/*!
\qmlproperty Scene3D AbstractGraph3D::scene
Read only Q3DScene that can be used to access e.g. camera object.
*/
/*!
\qmlproperty AbstractInputHandler3D AbstractGraph3D::inputHandler
Input handler. You can disable default input handlers by setting this property to \c null.
*/
/*!
\qmlproperty Theme3D AbstractGraph3D::theme
The active theme of the graph.
*/
/*!
\qmlproperty AbstractGraph3D.RenderingMode AbstractGraph3D::renderingMode
Defaults to \c{RenderIndirect}.
\table
\header
\li Render Mode
\li Description
\row
\li RenderDirectToBackground
\li Indicates the graph will be rendered directly on the window background.
This mode also clears the whole window before rendering the graph, including the areas
outside the graph.
Since the graphs in this rendering mode are drawn on the window background under other QML
items, the regular QML window clearing before rendering is suppressed. The graphs handle the clearing
themselves instead.
If the surface format of the window supports antialiasing, it will be used (see
\c {QtDataVisualization::qDefaultSurfaceFormat()}).
This rendering mode offers the best performance at the expense of non-standard QML behavior. For example,
the graphs do not obey the Z ordering of QML items and the opacity value has no effect on them.
\row
\li RenderDirectToBackground_NoClear
\li Similar to RenderDirectToBackground mode, except that the graph will not clear the whole
window before rendering the graph. This mode is better for windows where you have other custom items
besides the graphs that also draw on the window background. In that case you need to either take care
of the window clearing yourself or ensure that all areas of the window are fully covered with opaque
items.
If one graph in the window uses either of the direct rendering modes, then all other graphs in the
same window also drawn in direct modes should use the exact same direct rendering mode.
Otherwise some graphs may not show up, depending on the drawing order of the graphs.
\row
\li RenderIndirect
\li Indicates the graph will be first rendered to an offscreen surface that
is then drawn during normal QML item rendering. The rendered image is
antialiased using multisampling method if it is supported in the current environment and the
msaaSamples property value is greater than zero.
This rendering mode offers good quality and normal QML item behavior at the expense of performance.
\endtable
\note Antialiasing is not supported in OpenGL ES2 environments in any rendering mode.
\note Setting the \c antialiasing property of the graphs doesn't do anything. However, it is
set by the graph itself if the current rendering mode uses antialiasing.
\sa msaaSamples
*/
/*!
\qmlproperty int AbstractGraph3D::msaaSamples
The number of samples used in multisample antialiasing when renderingMode is \c RenderIndirect.
When renderingMode is \c RenderDirectToBackground or \c RenderDirectToBackground_NoClear, this
property value is read-only and returns the number of samples specified by the window surface
format.
Defaults to 4.
\sa renderingMode
*/
/*!
* \qmlmethod void AbstractGraph3D::clearSelection()
* Clears selection from all attached series.
