Hello,

I learn newly Java programming.

Because of this I have this small following question on it:

I must create several points from different 3 components (x, y, z), values.

e.g: I must create 2 points and (2, 4, 6) in Java3D of (1, 2, 3).

Does anybody have idea for it?

If somebody can help me, I am very grateful for it.

Greeting

Angelo

i cann't understand your problem can u briefly explain

Hello,

it is draw of a point.

Therefore I must draw 3 components (x, y, z), points.

It is a whole simple question.

But I learn Java programming completely newly.
Because of this I need help with it.

I am immediately available for a further explanation.

Many thanks

Angelo

Hello again,

I have found and continued to work on an example programme.

But I get, only black area without points.

Somebody has idea as I can further solve it.

Hello,

does nobody want further to help me at it?

Is anything not all right?
