Fix a memory leak, and brownian animation, if not motion.
I have 2 new files : personality.[ch]xx . They store the personality
data that would be deleted when the object is destroyed, instead
of staying in the animation maps. I also manage the current animation
step better and the towers are not flashing randomly now.
Makefile.am is updated.
modellib.cxx :
Add a branch between the model and its transformation to add
a unique identifier for the model. I called it "personality
branch" and it maintains a "current_object" in SGAnimation.
Animations specifically written to support it ( currently only
the timed animation ) can add a degree of variety among the
occurrences of the same model that would look otherwise cloned.
flash.[ch]xx :
Better compute the view vector. The flash is now syncronized with
its axis even at the edge of the screen.
animation.[ch]xx :
Lots of changes :
- add a condition to 'rotate', 'spin', 'translate' and 'range'.
When a condition is specified *and* it evaluates to false, the
animation becomes a no-op. Possible usage : no rotation during
daylight, LOD range variable along the day, ...
- use different durations for each branch in the timed animation.
Enable the use of multiple <branch-duration-sec>, one for each
<object-name> specified. Usage : strobes with flash light.
- allow randomization of the <branch-duration-sec>, by using
<random><min>_min_value_</min><max>_max_value_</max></random>.
The value computed once is between _min_value_ and _max_value_.
- implement model personality in timed animation. If
<use-personality type="bool">true</use-personality> is specified,
a different set of duration is created for every model in the
scenegraph using this animation. Best if used with randomization.
When using strobes where the population of the same object is
dense, it avoids the "cheasy" clone effect.
