taccgl™ currently supports a motion from one point to another with constant acceleration
and simultanously a rotation around a given point and axis (without acceleration).
The simplest and most common case is a linear motion from one point to another
along a straight line with a fixed velocity. This is a motion without (or with zero)
acceleration, the object's velocity does not change i.e. the object does not get faster or slower
during the transition.
taccgl™ provides methods to specify the starting and end point of
the motion (e.g. from, to, flyHome). Default is
the position of the animated HTML element. So as long as none of the methods
are used the object stays stationary, if only from is used it
moves from the given point to the position of the HTML element, if only to
is used it moves away from the position of the HTML element and if
both are used begin and end of the motion can be specified explicitely.
For rotations taccgl™ provides methods to specify axis and center point
In addition taccgl™ supports an animation from one point to
another with a constant acceleration. I.e. the object gets slower or
faster (depending on the direction of the acceleration) during the
transition. The acceleration is constant, so the object get
faster/slower at the same rate throughout the transition. This is
typically used for animations wherein the object slowly starts to move
or where an object becomes slower and slower until it finally
stops. taccgl™ provides methods to specify the velocity of the object
either at the beginning or the end of the animation (vBegin
and vEnd). Typlically one would specify a zero velocity at
the begin for an object that slowly starts to move. There are also methods
to set the acceleration explicitely (acceleration).
The acceleration and the velocities are, however, vectors having
a direction and so transitions necessarily perform linear
motions along a straight line but can also have a parabolic trajectory.
This happens if the acceleration does not have the direction (or
the reverse direction) of the line between starting and end point.
Note that more complex motions can be done by connecting
