如何使用鼠标与Java3D元素进行交互？

Question

I want the user to be able to change the length of a cylinder by clicking-and-dragging his mouse. How should I start on this ? Any form of help would be great.

Answer 1

Check out the example code here . The basic idea is:

• Use mousePressed() listener to detect a mouse press.
• Use Java3D picking API to detect if mouse press intersected shape.
• Use mouseDragged() listener to detect amount of change and update your shape accordingly.
