[JAVA3D] speed problem when using Canvas3D inside an existent frame app

[Arnaud Garcia]

Hello,   I had a  frame window with 3 panels for images visualization, theses images are reconstruction from a 3x3 matrix with JAI. I try to represent these data in 3D, and to test my application i just had a Canvas3D in the FRAME with a basic simple cube which rotate ! I don't understand why, but it is extremly slow to just see the canvas ! even if i do nothing.. I had a very good graphical cards (3D) and 1024 Mo of RAM. If i launch the rotating cube in an other frame it is better (but still slow),   Do you have an idea, of why including a 3D canvas  inside a existent frame application is a problem ? Do I have to  create the 3D canvas in a separate frame for better performance ?   thanks for your help arnaud
