Hi,

  I have a question about transformation. Suppose I have the following
scenegraph:

  BG(objRoot)
  |
  TG1(t3d_1)
  |
  TG2(t3d_2)
  |
  TG3(t3d_3)
  |
  thousands of Shape3Ds(s1,s2,s3,....s1000)

  (TG means TransformGroup,t3d_1,t3d_2,t3d_3 are Transform3D objects
associated with their respective TransformGroup).

  In live scenegraph, if I want to transform all of the Shape3Ds, by
applying a new Tranform3D(newT3d), is this correct?


     newT3d.mul(t3d_1);
     TG1.setTransform(newT3d);

  Will this automatically multiply t3d_2 and t3d_3,then transform all
Shape3Ds in live scene correctly?


  Thanks for any reply.

David
