public class SoInteractiveComplexity extends SoNode
Field interactive complexity node. This node allows the application to define different parameter values for certain fields of specific node classes, depending on whether a user interaction, for example moving the camera, is occurring. This means that while the camera is moving these fields will use a specified "interaction" parameter value, but when interactive manipulation is stopped these fields will automatically change to a specified "still" parameter value. Optionally, for scalar fields, the transition from interaction value to still value can be automatically animated using a specified increment.Note: The values specified in
SoInteractiveComplexity
override the values in the fields of the specified nodes during rendering. But calling getValue() on the fields still returns the value set directly into the field (or the default value if none was set).This is a powerful technique for maintaining an interactive framerate when interacting with GPU intensive datasets or rendering effects, while still getting a final image with very high quality and giving the user a "progressive refinement" effect while transitioning from interaction back to "still".
These settings are applied to all instances of the node class containing the specified field and are declared with a specially formatted string set in the
fieldSettings
field. For scalar fields like SoSFInt, the string looks like this:
"ClassName FieldName InteractionValue StillValue [IncrementPerSecond]"If IncrementPerSecond is omitted, StillValue is applied as soon as interaction stops. Else the transition from InteractionValue to StillValue is automatically animated. Because incrementing is actually done at each redraw, and redraw happens many times per second, IncrementPerSecond is allowed to be greater than StillValue.
In the following code, the field named value belonging to the class
SoComplexity
will be set to 0.1 during an interaction. When the interaction stops, value will be increased by 2 every second until it reaches 0.5. Effectively this means that the StillValue (0.5) will be reached in (0.5 - 0.1) / 2 = 0.2 seconds.SoInteractiveComplexity icplx = new SoInteractiveComplexity(); icplx.fieldSettings.set1Value( 0, "SoComplexity value 0.1 0.5 2" ); root.addChild(icplx); A time delay before changing the value, or starting the animation, can be set using the
refinementDelay
field.The field
interactiveMode
allows to force the use of the InteractionValue or the StillValue.Only a limited number of fields are supported by this node:

fieldSettings
public final SoMFString fieldSettings
Each string in this field specifies the interactionValue and stillValue for a specific field of a specific node class. The format is:For scalar fields ( SoSFInt32
,SoSFFloat
...)ClassName FieldName InteractionValue StillValue [IncrementPerSecond] For SoSFBool
fields (NumberOfSeconds = delay before switching state)ClassName FieldName InteractionValue [StillValue] [NumberOfSeconds] For SoSFEnum
fieldsClassName FieldName InteractionValue StillValue The following example defines values for a
SoSFFloat
, aSoSFBool
and aSoSFEnum
:SoInteractiveComplexity icplx = new SoInteractiveComplexity(); icplx.fieldSettings.set1Value( 0, "SoComplexity value 0.1 0.5 2" ); // isActive will switch to true 2 seconds after stopping interaction icplx.fieldSettings.set1Value( 1, "SoShadowGroup isActive false 2" ); icplx.fieldSettings.set1Value( 2, "SoVolumeRenderingQuality gradientQuality LOW HIGH" );
