[JAVA3D] cylinder: changing size once live?

[Josh Lisle]

hi. once a cylinder has been added to a scene graph, can you change its size?  i couldn't find any methods to change the height once the cylinder has been constructed.  if you can't change it, is there an efficient way to "destroy" it so that the memory isn't lost?  i have a program that requires drawing a 3D arrow that changes size. the user selects a point in space for the starting point of the arrow and i would like the arrow to be continually redrawn (rubberbanding?) as the user moves the end point.   thanks.   josh lisle [EMAIL PROTECTED]
