Your object is roughly 35 by 15 by 20 yet you only move your view platform back the nominal and your object is off to the side, thus you aren't looking at your object.
Bring the viewplatform back to about -50 or maybe -100 and adjust your backclip value and you should be able to see it.

I am trying to import 3ds image in Java3D But everything seems ok but the frame loaded is emty with totally black baground. I ve made a 3D max robot and converted to 3Ds, I also tried some 3ds files taken from the internet.
Can anyone tell me what's going wrong in my code? I also join the 3dsfile This mycode:
