I use the Monklypse project to write a program to
visualize the Algorithm in the Eclipse View.
But I don't know how to set the Coordinate
Because Every time I run the program my algo's dot may far from the center
Then My total graph will also far from the center
How should I do? Is there any function i JME can help me solve it??
thx!!
Well,…good question! You want to set a dot? Actually I would do it like creating a small sphere and
set it via sphere.setLocalTranslation(x,y,z) to the right spot. Or what exactly is the problem. I see
you say your dot's are far away from the center. what center? how do you set your dot's?
And of course I never use monklypse… 
hey there, seems your objects start at 0, 0, 0 and into the positive directions. to center it all just add a bounding volume to the rootNode, update it and then translate the rootnode by half the x, y and zExtent of the BoundingVolume (e.g. BoundingBox)
