Key Animation
We want to animate a key going down and up. The input for the rotation looks like:
The keys down (2) and up (8) on the numeric keypad move the cube up and
down. It is necessary to be in the select mode because in the other
case the viewer catches all events.
Let's have a look at the source and the
inventor file.
We might use a similar approach for the helical keyboard. Another
approach use a callback function of a SoTimerSensor to update the rotation.
