Hi, how can I do this. for example a cube on a horizontal that begans to climb for an inclinated plane. The Object3D class has only check for collision methods but they do not slide nor adjust the rotaion of the object, how can I do this?

You could use a 3rd part y(i.e. ODEJAVA) physics engine to do that.
