x3dom.nodeTypes. TexCoordDamper2D

The TexCoordDamper2D node animates transitions for an array of 2D vectors (e.g., the texture coordinates of a mesh). Whenever the destination field receives an array of 2D vectors, value begins sending an array of the same length, where each element moves from its current value towards the value at the same position in the array received.

Fields

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
destination MFVec2f [] The target value.
initialDestination MFVec2f [] The field initialDestination should be set to the same value than initialValue unless a transition to a certain 2D vector value is to be created right after the scene is loaded or right after the CoordinateDamper node is created dynamically.
initialValue MFVec2f [] The field initialValue can be used to set the initial value of value_changed.
isActive SFBool false X3DDamperNode isActive shows if the sensor is active
metadata SFNode X3DMetadataObject X3DDamperNode Field to add metadata information
order SFInt32 3 [0..5] X3DDamperNode The order field specifies the smoothness of the transition.
tau SFTime 3 [0,inf) X3DDamperNode The field tau specifies the time-constant of the internal filters and thus the speed that the output of an X3DDamperNode responds to the input. A value of zero for tau means immediate response and the events received on set_destination are forwarded directly. The field tau specifies how long it takes the output of an internal filter to reach the value of its input by 63% (1 - 1/e). The remainder after that period is reduced by 63% during another period of tau seconds provided that the input of the filter does not change. This behavior can be exposed if order is set to one.
tolerance SFFloat -1 -1 or [0,inf) X3DDamperNode If tolerance is set to its default value -1, the browser implementation is allowed to find a good way for detecting the end of a transition. Browsers that do not have an elaborate algorithm can just use .001 as the tolerance value instead. If a value larger than zero is specified for tolerance, the browser shall calculate the difference between output and input for each internal filter being used and stop the animation only when all filters fall below that limit or are equal to it. If zero is specified for tolerance, a transition should be stopped only if input and output match exactly for all internal filters.
value MFVec2f [] The current value.
