Hello, the attached file demonstrates what is, I think, a small bug in the dae module or in osganimationviewer (from osg 2.9.9).
The sample file contains two animated frames which follow the same
trajectory, one with LINEAR interpolation, the other with STEP interpolation.
I expected the y versus time plot to be like
_| _| _|
_| | _| | _| |
_| | _| | _| |
_| |_| |_| |
With the frame spending 0 seconds at y==4.
But I got
___ ___ __
_| | _| | _|
_| |_| |_|
_|
The first cycle is good, but when looping, the frame never comes back
to y=0.
I think this behaviour is bogus. However looking at the collada 1.4
documentation I cound not find any "looping behaviour" specification.
Do you think it is a bug ?
If so could it be fixed ?
Cheers,
Sebastian
