thank you for replying my message.
I have lots of problem with this thesis project, I need your help , like i have to rotate an arm by the angles given from the user as an input to a destination.
I have to calculate all the mathematical thing by my self. Waiting for your answers.. thank you..

Need Help! This is my thesis project for the university and I have got only 10 days to finish this project. I need help because I don't know The java3d package methods.
I am making a robot arm simulation.
I wanted the user to give the coordinates as an input and the arm will go to the given coordinate
Joint- How can I make joint/ link between objects?
How can I make a hierarchical structure?
Which classes should I use ?
Please someone help...

Rotations are best handled with quaternions. To rotate things nicely, create two Quat4f quaternions representing starting and ending angles and call interpolate() to smoothly blend between them.
On the other hand, quaternions take a bit of time to understand correctly, so you may simply want to create a Transform3D and use setEuler() to orient it with Euler angles.
If you don't know how to program in Java3D, it may take you more than ten days to both learn how to use it and write your program. If this program is only a minor part of your thesis, you may want to ask your professors for an extension on this part of your project. I'd also highly recommend reading that online book I posted in the last email. It's pretty short, and contains most of what you need to know to program in Java3D.
