I'm doing some research on the problem 4 now.

Best regards and by the way I really love your engine, it helped me so much this far.

Hy

I'm having problem!

I move two objects with method translate()

Here is my prompt output, just to be shure objects get same direction vector
RBG: (-3.0,0.0,0.0)
CONT: (-3.0,0.0,0.0)
TABLE: (0.0,3.0,0.0)
CONT: (0.0,3.0,0.0)

But objects move just the oposite way. And it doesen't matter if i rotate the other object also. (RBG & TABLE are childs in hierarchy)

I have no clue what colud it be



Sorry, 4 all those questions :oops:

Thanks!

I'll try that.

I'm pretty shure it doesn't

Is it possible to get an absolute position of child object in world.

Quote from: "eye1"Hello

I'm using this code to retrieve current position of Object in world

Code Select Expand

  private SimpleVector getParentTrans(Object3D model)
  {
     Object3D[] parents = model.getParents();
     SimpleVector sv=new SimpleVector();
     for (int i = 0; i < parents.length; i++) {
        if (parents[i] != null) {
           sv.add(parents[i].getTranslation());
           sv.add(getParentTrans(parents[i]));
        }
     }
     return sv;
  }

  public SimpleVector getCurrPosition()
  {
     SimpleVector sv = model.getOrigin();
     sv.add(model.getTranslation());
     SimpleVector par = getParentTrans(model);
     System.out.println("PAR: "+par);
     sv.add(par);
     return sv;
  }

it looks like it works fine!!!


But when I unlink child from parent it look like it is not removed from array which is returned by method Object3D.getParents(). Is that a bug, or i made a mistake??

Hello again.

Should above code work also when objects are rotated?

I'm thinking of going back to my previus child-->parent translations.

I will use jpct engine to create commercial product.
3D live warehouse visualisation.  It will be mainly used to visualize automatic HRL warehouses. It will be used for marketing purposes in company i work.

Thaks 4 this great engine. It really helped me so far.

I found a workaround, and now i translate objects seperatlly.
Thanks 4 help!
