hello,
I have a model and camera animation path exported from 3ds max to osg
format.
In OpenSceneGraph I want to jump to any point along this animation, so I'm
trying to extract the AnimationPath ControlPoints.
Here is the relevant part of the osg file:
PositionAttitudeTransform {
DataVariance DYNAMIC
name "Camera01"
nodeMask 0xff
cullingActive TRUE
UpdateCallbacks {
AnimationPathCallback {
DataVariance DYNAMIC
pivotPoint 0 0 0
timeOffset 0
timeMultiplier 1
AnimationPath {
DataVariance DYNAMIC
LoopMode LOOP
ControlPoints {
0 235.432098388672 9.58514785766602 0 0.500558972358704
0.499440401792526 0.499440401792526 0.500559031963348 1.00000011920929
0.999999761581421 1.00000023841858
...
So you can see the AnimationPath is stored within a callback within a
Transform. My problem is I haven't figured out how to extract this path.
There was a similar thread on this earlier (
http://groups.google.com/group/osg-users/browse_thread/thread/f89d14baf366385b/1c9e025662bf2544)
but the author was just after an initial position.
I looked at getUpdateCallback() but the interface of its return type
NodeCallback looks like a dead end.
Has anyone done this before?
regards,
Richard
