> Hi, > > I am new at Java 3D programming. I am currently reading the Collateral > tutorial. I have 2 questions, for which I have so far not seen any > solutions: > > Question 1: > I have an object, which I want to constantly keep aligned with a 3D line. > The line changes based on an external input (ex: msg received via JMS). > Everytime this happens, I want to rotate my object to be parallel to this > imaginary line. Note that this line is not visual, but exists only to > align the object. For example, every JMS msg generates a new Point3f > object, so I need to create a LineArray based on the last point and the > new point just retrieved, and then rotate my 3D object to align it with > this new line. > > Question 2: > All I've seen in the tutorial is how to manipulate the objects already on > display - that have been added to the scene graph. Is there a way I can > add new 3D objects dynamically, at run time? Using the above example, I > want to create a new 3D object when I get a certain JMS message, and add > it to the graph. Can I do this? Doesn't this invalidate the "compiled" > BranchGroup created at startup? > > > Is there any way I can do these things?
