Kyle,
Put simply "Z Buffering" is where for each point on your display screen
(x,y) a "z" value is kept. As polygons are processed the z values are
compared to determine whether a point on that polygon is in front or
behind the current z value. In other words, the Z buffer is a technique

If you use RecordableCanvas3D without the PortfolioApplication object,
you won't get that message (Something referenced in PortfolioApplication

You can also look how to do your own RecordableCanvas3D. Info on

You can add these things, but they must be added to a
branchgroup before being added to a live scene. ie To
add a behavior to a live scene use:
MyBehavior mybehavior=new MyBehavior();
BranchGroup adderGroup=new BranchGroup();
adderGroup.addChild(mybehavior);
liveScene.addChild(adderGroup);

Actually Cristopher, you are a little off. Notice that it's Vi-Vj-(Vj-Vk).
Distributing the minus into the parenthesis yields Vi-2Vj+Vk.
Now the vector sub, add, and length can be used, as J.Lee Dixon indicated.

Hi Tien,
...Your expression should evaluate to the following:
vector: W = (W1,W2) = ( Xi-2*Xj+Xk , Yi-2*Yj+Yk )
and then: value: Math.sqrt( W1*W1 + W2*W2 )

When you do it by hand, due to communitive property of vector matrix, the
equation
| ( Vi - Vj ) - ( Vj - Vk ) |
will become
| ( Vi + Vk ) |
since you multiply the -1 to the right side and add them.
and with using the Math.sqrt((Xi+Xk)^2+(Yi+Yk)^2)
will give you the amplitude of the vector.
Hi,
I'm using the com.sun.j3d.loaders.vrml97 loader and have a question about the

thank you for you reply
there are three point: i, j and k.
Vi = (Xi, Yi), Vj = (Xj, Yj) and Vk = (Xk, Yk) are the coordinates of i,j,k
I'd like to know how to calculate:
| ( Vi - Vj ) - ( Vj - Vk ) |
it's knew that : | Vi - Vj | = Math.sqrt( (Xi-Xj)*(Xi-Xj) -
(Yi-Yj)*(Yi-Yj) )

I think that the -1 is actually a subscript:

Look at the attached diagram to see what this means.
I also assume that the "||" mean you want the length of the vector.
Are you missing out on how to perform this vector math? This you can

Thank you for the response.

Hi Tien,
I can't make sense out of your expression for at least 2 reasons:
a) if Vi is a vector (xi,yi), the term 'Vi-1' doesn't make sense
b) 'Vi-Vi' would be (0,0), so all the Vi's in your expression cancel
out...
Maybe the '-' in your expression is really a '*' denoting the
(inner) vector
Hi everybody,
