Re: [JAVA3D] setTransform has "no effect" if its BranchGroup isn'tdetachedfrom its parent

Hi John, setLabel() is called before the "test" BranchGroup is added to its parent (before the "test" BranchGroup is live). When updateLabel() is called, the branchGroup has been added to its parent and is live. Is setTransform supposed to work differently if the branchgroup is live or not?

Hi, I am not quite sure what your question is but I did notice this: > I override this method to change the values in floatVerts > and set the new geometry to the Shape3D. I am not sure if this is what you are doing, but it sounds like you are calling setGeometry() or similar on your shape3D o

Hello ! Well I had the same problem few weeks ago. Mark Hood from sun has posted a WONDERFULL sample to show how to move the origin x0,y0,z0 where you want. I attached the code, hope that it can help you. So I think that you want to do the same thing than me : see more terrain on the canvas, for s

[JAVA3D] Terrain on 30% of the canvas height

  Hi all,   Does anybody know how to move the origin x0,y0,z0 down on the Canvas3D? I know, there are several ways to move up or down the viewers eye point using ViewPlatform or Avatar. However, if doing so the viewer still looks in the direction of the canvas center (slightly up, or down). W

Re: [JAVA3D] setTransform has "no effect" if its BranchGroup isn'tdetachedfrom its parent

Elisabeth, Most likely you are seeing the difference between the branchgroup being "live" vs not live. From the code you sent it does appear that you set the capabilities to allow the transform to be written but it's not clear exactly when this occurs (i.e. is the "test" branchgroup attached to

Hi, I would like to change the position of a (Raster) label (by changing Transform3D, see method updateLabel() below), but setTransform makes the old label vanish and there is no label at the new position. However, if I detach the Branchgroup, change the transform exactly the same way as before
