Dolphin Wireframe: Coordinate Interpolator Morphing

Event animation and interpolation is accomplished by ROUTE connections that pass events between nodes. Strong typing requirements ensure that only valid values are allowed to modify the scene graph.

The TimeSensor node produces output stimulus events that track the passage of time intervals using the computer clock.

Strictly typed interpolation values are produced by ScalarInterpolator, ColorInterpolator, PositionInterpolator, PositionInterpolator2D, OrientationInterpolator, NormalInterpolator, CoordinateInterpolator, and CoordinateInterpolator2D nodes.

The supporting Chapter 7 slideset and course videos (NPS, YouTube) for X3D for Web Authors are available online via X3dGraphics.com.
