BabylonJS - VectorPosition and Rotation

Run the demo links given below in your browser. In the demos given below, we have drawn the x,y and z-axis. There are numbers plotted on the x,y and z-axis in the positive and negative direction. Run the same in browser, change the values in case you need and draw your shapes, meshes, position them and see how they render in the x, y and z –axis.With the numbers mentioned on the x,y and z axis, it will be helpful to see how the positioning of the mesh is done.
