Hello all, I would like to know how can I animate (what class I have to use, how I use those classes) an object like a Sphere ou a Cube. I just need to make those objects rotate, translate and chage de fps rate.
You'll have to place the nodes which you want to animate separately under their own osg::MatrixTransform nodes, i.e. if the cube and the sphere need to rotate or move separately, use 2 matrix transforms. Then, you define one or several update callbacks on these nodes. You use the timestamp provided by the callback to compute the rotation amounts, you define the transformation matrix which you apply to the parent osg::MatrixTransform node. Have a look at the osggeometry example, more precisely at how the background is animated (the class MyTransformCallback is what you are looking for). Cheers Thibault Thanks,
