Getting the angle of 3d object

[xyzdcgan]

Hello, @stephomi ,

I have checked the code for getting the current angle of 3d object, and I am able to find the last value of x,y,z from _updateRotateEdit() method in Gizmo.js.

Where when i change any axis-green-blue-red i get the last value of that, but is there any other thing in code which can give us the current angle of 3d object exact x,y,z value.

Thanks @stephomi

The gizmo is applying the edit matrix at the end of the transformation operation : https://github.com/stephomi/sculptgl/blob/d543420e01e56c5e82087514fad8832c12ddffe3/src/editing/tools/Transform.js#L71

So the absolute rotation value from the initial position is lost.

You can avoid this behavior with :

  applyEditMatrix(iVerts) {
    var mesh = this.getMesh();
    var em = mesh.getEditMatrix();
    mat4.mul(mesh.getMatrix(),mesh.getMatrix(),mesh.getEditMatrix())
    mat4.identity(em);
  }

  // correct undo-redo
  pushState() {
    var mesh = this.getMesh();
    var tmpMat = mat4.clone(mesh.getMatrix());
    var undocb = function () {
      mat4.copy(mesh.getMatrix(), tmpMat);
    };
    this._main.getStateManager().pushStateCustom(undocb, undocb);
  }
  // also comment this._main.getStateManager().pushVertices(iVerts); above

It will impact how the symmetry is handled though (and probably other things I forgot)

I think there is a mistake @stephomi , For eg here is an object where assume x,y,z are 0,0,0

After changing that using gizmo, it look like

How can i get x,y,z of this current 3d object, that at what angle is it placed.

For finding that i used _updateRotateEdit() method in Gizmo.js. I am getting angles from that, but is there any other thing through which i can get x,y,z

Thanks @stephomi

You can get if from the mesh matrix (if you use my code above)

Yes, i added that code and got the rotation values thanks for that @stephomi , also can you tell if can get what is angle between the plane and 3d object, means the grid/surface and 3d object which is loaded. @stephomi Thank You.
