JMonkeyEngine to create a cube

[blackraven1425]

I'm using JMonkeyEngine, and trying to make objects in a cube. Meaning, a three-dimensional cube out of objects (Spheres, to be specific). However, the logic is escaping me. This is what I have so far:

for(int i = 1; i<9; i++){
for(int j=1; j<9; j++){
for(int k=1; k<9;k++){
add object
}
}
}

I'm really sitting here scratching my head, cause this gives a triangle viewed from different angles to be a different triangle. It gives a sliver of a cube. I'm looking for an algorithm for a whole cube, in pseudo code or java so I can trace it out and understand how to do this.

oh shoot, i forgot to add that the add object is at i,j,k

Duh duh = duhs.get((i*j*k )-1);
duh.setLocalTra nslation(new Vector3f(i, j, k));

the actual source code i have working that gives the triangle
that canged at different angles

Node n = new Node();
for(int i = 1; i<9; i++){
for(int j=1; j<9; j++){
for(int k=1; k<9;k++){
AtomSphere atom = atoms.get((i*j* k)-1);
atom.setLocalTr anslation(new Vector3f(i, j, k));
atom.setSolidCo lor(ColorRGBA.g ray);
n.attachChild(a tom);
}

}
}

AtomSphere atom = atoms.get((i*j* k)-1);

This can't be correct; e.g. it fetches the same atom for values i,j,k == 2,3,4 and
i,j,k == 4,6,1

kind regards,

So, I'm still lost on how to traverse the cube correctly. i*j-k doesnt work right, it only works for the last square in the cube. The rest that shows up is one edge of the cube.

Just guessing from the little code snippet you showed us:

for(int i = 0; i<9; i++){
   for(int j= 0; j<9; j++){
      for(int k= 0; k<9;k++){
         AtomSphere atom = atoms.get(81*i+9*j+k);
         ...
 

This is assuming that 'atoms' is a simple list that stores all the atoms. The
three indexes i,j,k are transformed to a single linear index value.

kind regards,

Or maybe (to keep arithmetic out of it...

int atomIndex = ???;
for(int i = 0; i<9; i++){
   for(int j= 0; j<9; j++){
      for(int k= 0; k<9;k++){
         AtomSphere atom = atoms.get(atomIndex++);
         ...
 

No one in this forum has stepped forward and admitted to knowing JCodeMonkey, so you need to explain things better or see if that product has its own forum.
