Hey there, me again. I am trying to 'automate' a translation of a 3D model that I input into jPCT. But because the center of this model is not at the world's origin, I do an inverse translation of this 3D model so that I can view it at the origin in world space. However, I realise that float somehow does not go into the negative region (but googling around seems to suggest that float can be negative). This is what I intend to do:

`cube=Object3D.mergeAll(Loader.loadOBJ(inputmodelFile, null, 1));`

float xT=-cube.getCenter().x;

float yT=-cube.getCenter().y;

float zT=-cube.getCenter().z;

Log.w("cube center", String.valueOf(xT)+ " "+ String.valueOf(yT)+ " " + String.valueOf(zT));

cube.translate(xT,yT,zT);

However, this does not perform the translation at all because the Log meesage tells me -0.0 -0.0 -0.0 . In fact, cube.getCenter has some solid numbers, for my models the center is actually (10,50,-100). I tried other methods to get the figures into the negative region, ie multiply -1f, using -=, but none seems to work. Could anyone help explain where have I gone wrong?
