newbie question, how to rotate around a designated axis in jPct ?

[guillaume]

can someone show me some code ? I am new to opengl and jPCT programming. thanks.

Like so: http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Object3D.html#rotateAxis(com.threed.jpct.SimpleVector, float)

if I use this api,  how should I represent a axis  (for example  x=4)  in vector form ? thanks.

x=4 is no axis. I'm not sure what you are after...maybe setRotationPivot() is more what you want?

oh, I mean a line parallel to Y axis and pass through  point (4,0,0). how can I rotate around this ?

[EgonOlsen]

By offsetting the rotation pivot. Try object.setRotationPivot(4,0,0) and do a rotateY() afterwards.
