Hi Tim,
I am finished my project, it treated about animation of articulated structures.
It consists in animate simple scenes using keyframing. I don't have all the
data of the motion, the user moves interactively
the objects and register every keyframe, one time the sequence of keyframes had
been completed I interpolate these using the class TCBSplinePathInterpolator (
a Kochanek spline). The program have some primitives cube, sphere, and a biped
(something similar to a human :) it is a hierarchical figure and the results
are greatly satisfactory.
About your questions, I have a idea, overwrite the method postRender(), this
method is invoked by J3D after rendering the canvas, (see the API), inside this
method update all the transformGroups to the next scene. If it not works
perhaps you have to stop the java renderer (canvas3D.stopRenderer()), update
the scene and finally start Renderer (startRenderer()).
I hope it will be util. Tell me if it works.
Good Luck !!
