Your question is pretty general, but the libGDX 3D API is pretty stable, easy to use, and has many features.
It can not only display basic 3D shapes like spheres and boxes, but also load complex models through .obj or .fbx files. It supports animation, normal and mirror maps, a basic lighting system with spotlights and directional lights. The latest version also adds a high-performance 3D particle engine, including an editor for creating these effects.
In addition, it supports bullet physics, which is a 3D physics engine that works well with the libGDX 3D API.
