3D in libgdx is pretty active lately. Bach and Mario are actively working on the 3D APIs. Xoppa has contributed a bunch of stuff for Bullet. Run LwjglTestStarter and choose BulletTestCollection, which is really cool and runs surprisingly well on phones and Ouya.

I don't use LibGDX, but in general, when looking to learn something, google more specific aspects. Learn what you need, ignore what you don't. Then finally you can put the new knowledge to use.

Personally, I think voxel engines, no matter how simple, are a good way to start off because any working with Tile maps that you have done is quite easy to implement again except with 3 Dimensions.

It all depends on your learning speed.

3D is a lot of math unless you use a high level tool like Unity. Even then there is a lot of math involved.

3D is 2D but with an extra dimension. Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked

If you don't understand how that helps, stick with 2D for a while.

BUT WHATEVER YOU DO, DON'T GO ANYWHERE NEAR 4D Yawn Clueless Huh Shocked Smiley Cool Tongue

3D is not so much learning from tutorials, but more application of the things you learnt in 2D.

To understand 3D, or comprehend rather, you need to understand matrices and vectors. Moreover you need to know why matrices are so useful.

In essence, learning matrices is learning how to manipulate a collection of points (a plane) in various useful ways.

Here's a link someone on jgo has posted:

GDX has a ton of test programs in the source distribution: start here for one example, and see Shapes.java in the same dir for the way it uses Mesh to store the geometry.  You'll notice it's quite raw, but that's because gdx doesn't have much 3d support to speak of.  I hear tell that they're working on more 3d support, but none of it's landed yet as far as I know.
