X3D: 3.3
Component: Interpolation

x3dom.nodeTypes. ScalarInterpolator

The ScalarInterpolator node linearly interpolates among a list of SFFloat values to produce an SFFloat value_changed event. This interpolator is appropriate for any parameter defined using a single floating point value.

HTML Encoding and Default Values

<ScalarInterpolator key='[]' keyValue='[]' metadata='X3DMetadataObject' set_fraction='0' ></ScalarInterpolator>




Constructor for ScalarInterpolator

Name Type Argument Default Description
ctx Object <optional>
null context object, containing initial settings like namespace


These are the X3D / X3DOM fields of this node. Values should usually be received / set as strings via DOM functions (i.e., using setAttribute("myFieldName", "myFieldValue") and getAttribute("myFieldName")).
Name Type Default Value Range Inheritance Standard Description
key MFFloat [] X3DInterpolatorNode The key field contains the list of key times, the keyValue field contains values for the target field, one complete set of values for each key. Interpolator nodes containing no keys in the key field shall not produce any events. However, an input event that replaces an empty key field with one that contains keys will cause the interpolator node to produce events the next time that a set_fraction event is received.
keyValue MFFloat [] Defines the set of data points, that are used for interpolation.
metadata SFNode X3DMetadataObject X3DInterpolatorNode Field to add metadata information
set_fraction SFFloat 0 X3DInterpolatorNode The set_fraction inputOnly field receives an SFFloat event and causes the interpolator node function to evaluate, resulting in a value_changed output event of the specified type with the same timestamp as the set_fraction event.
