The main theme of this month for me was "Learn how to use Terra and then fix it." Here's a comparison of the previous version of Terra and the new one:

Bugs

p30 8


Crushing the bugs!

  • Obsolete libraries prevented building (fixed)
  • Terra material ID bug prevented air from generating (fixed)
  • Broken 1D to 3D culling calculations (fixed)
  • Texture bug (fixed)
  • Shader bug (fixed)

Performance

Startup: 2 min 20 s
FPS: 60 - 80
Memory usage: 1 400 MB
Memory and loading times have gone up, and generation is slow. This means we need to focus on optimizations for now.

Weltschmerz

I optimized world generation code by removing fortune algorithm in Weltschmerz, which significantly improved performance. Result is a much smoother map.

p30 12


But it also broke adjusting seas and shorelines. The generation of detail is now so high that 1 pixel == 1 sector. Here is schema to imagine example hierarchy of world size in final release.

p30 13

Weltschmerz

We keep important parts of the game as modules for moddability. Terra only does what it's told to do and contains no behavior logic. This means that Weltschmerz needs to provide the world generation logic and it is kept separate from Terra. The world data is passed to Terra as a flat array that Terra understands.

Progress

Right now we can generate about 1000 chunks with good FPS on an average 5 year old GPU. This equals to a flat terrain which is approximately 500 x 500 meters in size.

Our next goals are:

  • Optimizations.
  • Support for custom meshes.
  • More performance tests.

We are looking for more coders to join the project. Contact information can be found on our website:

See you later!

I wonder if this game engine can do something similar to CryEngine 2 or 3, in example, talking about the generated environments. It would be great to make an scenary in both engines and compare the results. I'm learning to use this engine (jME 3) because I have some ideas I would like to materialize, and I know Java enough to start with it, but I have no experience in Game development; that's why I would like to know if this engine can generate realistic environments as CryEngine (2 or 3), or if there are some limitations (about performance or something else) for that (excluding of course the quality of textures and models).

It really comes down to the quality of your models and your scene composition skill. Nothing performance wise is gonna stop you from making a scene in jME3 that's as good looking a what you see in a CryEngine game, but those scenes usually took several thousand expert man hours to put together.

This engine is the best thing for java game creation.
but still its a bit buggy and the SDK's gui is super slow and buggy.
so I'm using direct LWJGL.

Did you try the RC1 release yet? There's been some major improvements in the SDK, including a big performance boost.

Developer of 3079 here -- My game wouldn't have existed if it wasn't for this engine. This engine has done so many great things for me, and knowing it is purely Java based allows it to be completely cross-platform without any extra work. Did I mention it is free? These guys deserve tons of credit. This engine is fast and full of features. It also includes a complete Software Development Kit with terrain editors and all sorts of gizmos. Highly recommend this! In response to other review comments…
