This is a toy project. Guardian II is still my main game.     Infinite World or fixed size Simplex Noise Generation with randomized octaves. Lighting. Fog. Basic Movement (For test purposes. Real movement soon). If any of the other people currently making voxel engines (or anyone else) want some help with something, feel free to ask. |

Can I ask you how, or where, you learned perlin noise?

Fixed-function or programmable pipeline?  |

That's looks very nice! Thanks for putting that on, it's inspiring.  |

That is epic, very hilly and some nice formations.

Be nice to have the best of both in one world. I'm thinking of using a diamond star algorithm, do you have any advice/thoughts on that?
Also, I take it simplex produces a 2d height map? Are there any 3d implementations?
It's looking great tho. Your obviously drawing lots of faces. Do you know how many?

Depends what I set the view distance to.
It works fine for me on 9x9x9 chunks. In fact, lag is caused by chunk loading. I should fix this.
Which equals 144^3 potential cubes. Probably (144^3)/2 cubes.
Most cubes are invisible.
On an almost flat world, there will be 1 cube per x,z coordinate. The cube would have around two faces visible on average.
(144^2)x2 = 41472 faces on an almost flat world.
As for simplex noise generation, I'm still looking for a way to have sections of flat and mountains.
You could try multiplying two (or more) octaves (between 1 and -1) and multiplying that by the height.

2 optimisations:
- Uses multithreading for chunk loading.
- Blocks are organised in chunks by an array instead of a HashMap of Vectors.
Result:
9^3 chunks (of 16^3) rendered:
Uncapped Framerate: ~110fps when loading new chunks, ~160fps when staying in one chunk.
RAM usage dropped massively due to less Vectors.

You could probably just use a Vector pool, no? |

A while ago I made almost all of the vectors immutable and only left mutable ones for things like player position etc
If I ever hit problems again I could refactor though.
Thanks for the suggestion, I never thought of that.

Looking good with the extra definition provided by the grass/soil texture.
I think I'm going to need some mulithreading for loading! That's next on the list..
What you planning next?

Block breaking/building/interacting
I'm currently trying to get it to pick the right block, then I'll move onto getting the right face.

Can you please tell me how you did the frustum culling? I am trying to do it for last 4 hours, but i can't make it work how it should. Here is how i did the frustum faces loading: 1

Block Picking is workinghttp://pastebin.java-gaming.org/ddc736e1252 for source. The Face class is just a Block, the block's position, and a useless integer (supposed to be for finding which face) It was hacked together, so there will be optimisations. Also, it sometimes fails when looking diagonally in all 3 directions. Now I'm working on getting it to find the correct face.

Do you use occlusion culling? If so, do you use a bunch of rays to test all the blocks? Or how do you do it?

Is it better to make cubes out of triangles or quads?
