tutorials for libgdx in 3d?

[wreed12345]

I have been doing a lot of google searches and havent found anything... Have any of you guys found any source code or tutorials to look at?

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.

I seem to recall you struggling with 2D. Now 3D?

lol i struggle with trig, and i dont really want to make a 3d game i just have never experimented with it, i know it will be too hard just wanted to know where to start

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

soy you guys dont know of any 3d tutorials? :/

3D is 2D but with an extra dimension.

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

BUT WHATEVER YOU DO, DON'T GO ANYWHERE NEAR 4D

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.

are there any guides or examples for libgdx related 3d?

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.
