Hello everyone!
I made a small voxel-engine!
“Pictures can say a thousand words…”

A video of me playing a bit around in the engine.

-need to rewrite technical information-
What do you think of this?
Have a nice day!
Very impressive 
Would be interested to know about the server/client model - I’m looking at putting in multiplayer into mine.
Thanks
The networking is based on raw Java NIO/TCP and my own network protocol called NetPac.
It’s pretty fast. It takes just 8-20ms to send 8 chunks from one PC to another PC in a local network.
Sounds good to me.
I need to look into doing something similar, any advice of where to look?
Thanks
In the Networking or the Voxel handling?
Here is a more detailed explanation of the Server/Client model.
‘C’ is the Client, ‘S’ is the Server. ‘>>’ means that ‘X goes from A to B’.
C: Create Socket and try to connect to Server
S: Accepts Connection
C >> S: Sends Login Request Packet
S: Checks if the login is valid (Player isn ot already there/Server is not full, etc.etc.)
Not-Accepted: Send ConnectionKill Packet to Client and Stop.
Accepted{
S >> C: Send Asset-Count and Assets //NYI
C: Receive Assets and use them //NYI
C >> S: Send the Asset Packet back
C: Create local World Instance
C: Go into infinite Packet reading loop
S: Start a new Thread and go into an infinite Packet reading loop
S >> C: Send Spawn-Area Chunks
// LOOP START
C: Read every Packet and execute it using the assigned Handler
S: Read every Packet and execute it using the assigned Handler
}
Btw:
The NetPac system is a modular multipurpose tcp-packet networking system i made for my applications.
How Packet’s are handled still has to be specified for every Server/Client instance.
But that isn’t really hard to do.
Hi,
Network handling. I take it the app needs to be running on both computers - just wanting to do something like in MC where you can search for LAN games and join them.
Thanks
How to search for LAN-Games:
Send a UDP Packet with some client informations to all units in a network.
This happens by sending the UDP packet to the address ‘255.255.255.255’.
When a Server receives one of these messages, it just has to sent a info packet back to the client.
Edit:
I managed to work on this project again.
The result is a (nearly) 1km view distance!
Some pictures: (The fog is a bit too close I think)

The FPS where just around 60 while I took the pictures.
reopened on request :point:
Yay! Now I can post that update video!

Would anyone want to try out the prototype?
Have a nice day!
This is really impressive, nice work!
Very nice. Every voxel project on this forum that I’ve looked at seems to use display lists. Is there a reason that they’re used versus VBOs? I’m just curious.
I am not using displays in the way everyone else does.
GL11.glNewList(...)
VertexArray.batch()
GL11.glEndList()
Its pretty fast. I tried to switch it out with VBO’s once, but it was terribly slow compared to this method.
Although I think it doesn’t work on every graphics-card…
Have a nice day.
I believe Minecraft also uses the display list and vertex array method to render too, just for reference.
Good job Longor! It’s impressive.
Yes, Minecraft does use that method too.
I realized after a lot of testing that this method is the fastest, and easiest way, for rendering tons and tons of chunk-meshes.
And it has a surprisingly small memory-foorprint!
Have a nice day.
