Class TLspShapePainter
- All Implemented Interfaces:
ILspPaintGroupsChangeListener,ILspEditableStyledPainter,ILspPainter
ILspShapeDiscretizer
is used to create a discretized representation of the shape's geometry. By default,
TLspShapeDiscretizer
is used. By consequence, this painter supports all shapes supported by this discretizer. Adding
support for additional shape types will usually be done by extending the shape discretizer, and
calling setShapeDiscretizer.
The geometry that is painted for a given style is retrieved using the corresponding ALspStyleTargetProvider. If a style target provider is not available, the object will be passed
to the shape discretizer directly, which supports most ILcdShape implementations
by default.
Geo-referenced meshes are not passed to the discretizer, as the meshes are assumed to be discretized.
Styling of the painted shapes and meshes is performed through the set ILspStyler. Separate
stylers can be configured depending on the TLspPaintState. This allows different styles for, regular, selected, or edited objects.
Note that you should avoid using this painter directly, have a look at TLspShapeLayerBuilder instead.
In all cases, the painting is conditional based on the presence of an appropriate
style in the output of the ILspStyler. The following styles are supported:
TLspFillStyle: can be applied to closed shapes such as circles or polygonsTLspLineStyle: can be applied to closed and non-closed shapes such as arcs and polylinesTLspLineStyle: can be applied to polylinesTLspComplexStrokedLineStyle: can be applied to closed and non-closed shapes such as arcs and polylinesTLspWorldSizedLineStyle: can be applied to closed and non-closed shapes such as arcs and polylinesTLspIconStyle: can be applied to point shapes and point listsTLspIconStyle: can be applied to point shapes and point listsTLsp3DIconStyle: can be applied to point shapes and point listsTLspVerticalLineStyle: can be applied to point shapes and point listsTLsp3DMeshStyle: can be applied to geo-referenced meshes
TLspFillStyle and TLsp3DMeshStyle. You can for instance specify
two icon styles for a point, in which case both icons will be shown on top of each other.
Visualizing density plots
This painter can also be used to visualize density plots.
This is done by letting the styler submit TLspDensityLineStyle, TLspDensityLineStyle
or TLspDensityPointStyle instances.
The colors used for the density plot can be controlled by also passing a TLspIndexColorModelStyle instance.
Limitations
- Selection and editing is not supported for density plots. For those paint states, the painter won't paint anything.
- Only one elevation mode is supported for the whole density plot. Using a mix of different elevation modes in the density styles will have no effect.
-
Only one
TLspIndexColorModelStylecan be used for the whole density plot. Submitting multiple ones in the styler will have no effect. Note that the sameTLspIndexColorModelStylemust be submitted for each object. -
Mixing
ALspDensityStyleinstances with regular styles is not supported and will throw exceptions. When painting density plots, the styler should only submitALspDensityStyleinstances and optionally a singleTLspIndexColorModelStyle.

Creates a new shape painter using the given styler for default styles.- Parameters:
aDefaultStyler- The styler that will be used forPaintState.DEFAULT.
-
TLspShapePainter
public TLspShapePainter()Constructs a shape painter that will be initialized with default styling that allows basic visualization of most geometries supported by this painter. Default styling is available for surfaces, curves and points, and is defined by the defaults in the styles themselves. AnILspCustomizableStyleris used, so the default styles can be enabled/disabled or replaced.- See Also:

Method Details
-
getStyler
Description copied from interface:ILspPainterReturns the styler used by this painter for the givenPaintState. Can return null in case the painter does not use or expose a styler.- Specified by:
getStylerin interfaceILspPainter- Parameters:
aPaintState- the paint state for which a styler is requested- Returns:
- the styler used by this object, or null.
-
registerLayer
public void registerLayer(ILspInteractivePaintableLayer aLayer, TLspPaintRepresentation aPaintRepresentation) Description copied from interface:ILspPainterRegisters a layer with this painter. This notifies the painter that it is going to be used in combination with the given layer, for the given paint representation. This allows it to implement setup code if necessary, or to keep track of all layers on which it is set. Layers registered with this method must be unregistered when the layer stops using this painter, usingILspPainter.unregisterLayer(ILspInteractivePaintableLayer, com.luciad.view.lightspeed.layer.TLspPaintRepresentation).- Specified by:
registerLayerin interfaceILspPainter- Parameters:
aLayer- A layer with which this painter will be used.aPaintRepresentation- The paint representation for which this painter will be used.
-
unregisterLayer
public void unregisterLayer(ILspInteractivePaintableLayer aLayer, TLspPaintRepresentation aPaintRepresentation) Description copied from interface:ILspPainterUnregisters a layer from this painter. This notifies the painter that it will no longer be used in combination with the given layer, for the given paint representation. This allows it to implement cleanup code if necessary. Layers unregistered with this method must have been registered before calling this method with the methodILspPainter.registerLayer(ILspInteractivePaintableLayer, com.luciad.view.lightspeed.layer.TLspPaintRepresentation).- Specified by:
unregisterLayerin interfaceILspPainter- Parameters:
aLayer- A layer that needs to be unregisteredaPaintRepresentation- The paint representation for which this painter was used with aLayer
-
setStyler
Description copied from interface:ILspEditableStyledPainterSets the styler used by this object for the givenPaintState.- Specified by:
setStylerin interfaceILspEditableStyledPainter- Parameters:
aPaintState- the paint state for which to set a styleraStyler- the new styler for the painter
-
addPropertyChangeListener
Description copied from interface:ILspPainterAdds aPropertyChangeListenerto the list of listeners that must be notified when any of the properties of thisILspPainterchanges.- Specified by:
addPropertyChangeListenerin interfaceILspPainter- Parameters:
aListener- the listener that from now on will be notified of all changes to properties of this painter
-
removePropertyChangeListener
Description copied from interface:ILspPainterRemoves aPropertyChangeListenerfrom the list of listeners. This listener will no longer be notified of any changes to the properties of thisILspPainter- Specified by:
removePropertyChangeListenerin interfaceILspPainter- Parameters:
aListener- the listener that no longer will be notified of any changes to properties of this painter
-
paintObjects
public TLspPaintProgress paintObjects(ILcdGLDrawable aGLDrawable, List<TLspPaintGroup> aPaintGroups, TLspPaintPass aPass, TLspContext aContext) Description copied from interface:ILspPainterPaints the specified groups of objects into a view. The objects are partitioned into
TLspPaintGroups, which are created by the layer which invoked this painter. Painters are advised to also implementILspPaintGroupsChangeListener, which allows them to keep track of changes to the supplied list of paint groups. This way, the painter can exploit temporal coherence and perform its work in the most optimal way.This method returns a
TLspPaintProgresswhich describes the completeness of the paint operation. If the painter scheduled one or more tasks to be executed asynchronously, it may return from itspaintObjects()method before having rendered all the objects it was given. In this case, the returned progress object can describe the amount of work that has been done and the work that is still remaining.- Specified by:
paintObjectsin interfaceILspPainter- Parameters:
aGLDrawable- theILcdGLDrawablein which the objects are to be paintedaPaintGroups- the objects to be paintedaPass- the current paint passaContext- provides context information to the painter- Returns:
- a
TLspPaintProgressobject describing the completeness of the paint operation
-
toString
-
getShapeDiscretizer
Gets the shape discretizer. The shape discretizer is responsible for converting the objects being painted into a mesh object.- Returns:
- the shape discretizer
-
setShapeDiscretizer
Sets the shape discretizer. The shape discretizer is responsible for converting the objects being painted into a mesh object.aShapeDiscretizershould express the discretized positions int world coordinates.- Parameters:
aShapeDiscretizer- the shape discretizer- See Also:
-
getRequiredOpenGLProfile
Description copied from interface:ILspPainterReturns the minimum required OpenGL profile that a view must support in order to be compatible with this painter.- Specified by:
getRequiredOpenGLProfilein interfaceILspPainter- Returns:
- a
TLspGLProfile
-
prepareChanges
public void prepareChanges(List<TLspPaintGroupsChangedEvent> aEvents, Object aEventId, ILspPaintGroupsChangeListener.Callback aCallback) Description copied from interface:ILspPaintGroupsChangeListenerCalled when the paint groups will change. The listener should prepare the necessary changes for the events but not commit them yet. TheILspPaintGroupsChangeListener.Callback.changesReady(java.lang.Object)method must be invoked when the listener is ready to commit the changes. IfaEventIdisnullthen the changes may be committed immediately. In this case there will be no call toILspPaintGroupsChangeListener.commitChanges(Object).Note that it is not mandatory to do this two-phased commit cycle. You may commit or apply the changes immediately, but you still must invoke the callback.
