Public propertyfieldSettings

Each string in this field specifies the interactionValue and stillValue for a specific field of a specific node class.

Public propertyinteractiveMode

Interactive mode.

Public propertyIsDisposable
ISafeDisposable interface implementation.
(Inherited from SoDisposable.)
Public propertyrefinementDelay

Time in seconds after interaction stops before field values start to be increased.

Public propertyUserData
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.)

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 OIV.Inventor.Nodes.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 OIV.Inventor.Nodes.SoInteractiveComplexity.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 OIV.Inventor.Nodes.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[0] = "SoComplexity value 0.1 0.5 2";

A time delay before changing the value, or starting the animation, can be set using the OIV.Inventor.Nodes.SoInteractiveComplexity.refinementDelay field.

The field OIV.Inventor.Nodes.SoInteractiveComplexity.interactiveMode allows to force the use of the InteractionValue or the StillValue.

Only a limited number of fields are supported by this node:


InteractiveComplexity {
fieldSettings []
refinementDelay 0.5
interactiveMode AUTO
