Hi,
I need to solve these problems :
1) to determine if a 3D point is in or out a polygon (in 3D)
2) draw x,y,z cartesian ases and point, curves or segments in 3D in a
canvas.
Do you know a class to do it ?

A single class to do those two only marginally related tasks? I don't
know of any such class, but there is an API (i.e. a collection of classes)
available called Java3D which may help you solve your problems:

Yes, I know, but I think that it's too complex for my goal.
But now I will use it, I have no choose.

You can always roll your own, you know. And there are many good books on the
mathematics of 3D graphics. Fun stuff.

Know I use Java3D, it's not easy,but it's a great package !!!!
It's a sine that it hasn't a method for to know if a point is in or out a
3DPolygon as contains() in Polygon.
