Keyframe Animation

In contrast to most 3D applications, Ventuz does not associate animations with the scene directly. Instead, the curves, keyframes and logic information of an animation all belong to a Keyframe Animation node. A scene can therefore have any number of independent animations each with its own set of animated properties, timeline and keyframes. The information of an animation can be edited in the Animation Editor. For more information on animations in general, see Animation and State Engine.

Each Keyframe Animation node contains a timeline independent of the global scene time. To play an animation, a Control Node has to be bound to the Control Input Property.

Animation Logic

If an animation contains an Animation Logic, the nodes icon is colored blue instead of green and additional input as well as output properties are available.

Then each node will provide a number of Input Methods that can be used to interact with the state machine. For an explanation on the semantics of Begin/Next/Prev/Present/End, please refer to Animation Editor. Additional methods can be added by using the Custom Model button. When the AutoBegin property is true, the State Machine will jump to the Begin state when the scene is being opened.

The Global Speed specifies how the animation timelines are mapped to the global time. If a keyframe animation is 10 seconds long and the Global Speed is at 50%, the animation will take 20 seconds to play.

On the output side, there are a number of Output Properties that give feedback on the current state of the State Machine. The IDs and names returned here can be set as properties of the states in the Animation Editor.
