3D Randomly Generated World

WIP games, tools & toy projects
#1

Inspired by The Fog - Survive, State of Fortune, Far Sky, and many others, I have created a 3d randomly generated world using simplex noise in a couple days. All you can do right now is walk(or fly) around and generate new terrain. Current frame rate for me is ~90 230 1500 fps limited to 60fps! I am curious as to what others are getting.

[Controls]
LMB/RMB - grab/release mouse cursor
WASD - movement
E - toggle flying
Q - fly supersonic
R - reload world with current settings
L; - decrease or increase persistence
,. - decrease or increase the largest feature
[] - decrease or increase the view distance
nm - decrease or increase the water quality
jk - decrease or increase the water wave height
CTRL - zoom
ESC - quit
LSHIFT - slow walking

Current Version: 0.0.5.2
[Download]

[Latest Update]

  • Water!
  • Performance greatly improved
  • You can now launch directly from data/launch_direct
  • VSync option in the launcher
  • Increased available display dimensions

[Known Bugs]

  • Collision mesh is buggy in negative coordinates
  • Screenshots don’t take the whole screen in fullscreen mode unless you explicitly change the dimensions

Please tell me about bugs that you find!

[Update 0.0.5.3 DEV]

Any criticism or feedback is much appreciated. :smiley:

[V0.0.2]
-Major Performance improvement
-Now normals are calculated only once per vertex (removes some artifacts)
-Chunk loading system (very large maps now possible)

#3

I had a bit of a blast in it, I found it to be very smooth!

I really like the texture you’ve got going on for the grass, it makes it seem nicer than a lot of grass textures you see around.
It kinda reminded me of this:

Although, I found that when I looked as far down as I could, the world starting glitching a bit.

#4

I think you forgot something about linux with the natives.

#5

@NegativeZero Yes, that’s the picture I thought of too :wink: I’m trying to fix the camera issue, I just need to limit how far you can look down because when you get past looking straight down, your view flips and it glitches around.

@Wessles
Try to download again. I updated lwjgl and the natives. I also grouped all the natives in a single folder.

#6

Unfortunately, still the same error :frowning:

#7

@Wessles That’s strange, I’m loading the natives directly with this code:

    	final String userDir = System.getProperty("user.dir");
    	final String nativeLibDir = userDir + File.separator + "native";
    	System.setProperty("org.lwjgl.librarypath", nativeLibDir);

Edit: That’s strange, now I can’t run the jar on windows. Same error. (It runs in eclipse though)

#8

Ok, try one more time. If this doesn’t work, then I don’t have any idea on how to fix it.

#9

Wait, why are you setting the natives path to the “user.dir” directory? That refers to the user directory in the file system, not where the jar is located.

#10

It seems to work fine for me, wherever I put the jar.

C:\Users\Longarmx\Documents\workspace\Simplex Noise\native\windows\

Is there a different property I should use?

#11

Sorry, read a bit fast; “user.dir” is the property to use, but on OS X it fails:

java.lang.UnsatisfiedLinkError: Can't load library: /Users/simn/native/macosx//liblwjgl.dylib
#12

It seems like the JVM gets run from /Users/user in OS X no matter what (that leads to every path from the directory of the jar to be referred to the home directory). I advice you to use JarSplice or place the natives at a temporary directory like “java.io.tmpdir” and load them from there.

#13

Sorry about that. It seems that the smallest of errors get past me (double file separator). Try the download again. Hopefully I’ll eventually get this right :wink:

#14

Lol, just totally forget what I said. :stuck_out_tongue:

When I do:

java -jar /Users/simn/Downloads/3D\ World/3D\ World.jar

It starts the JVM from /Users because that’s the current directory I’m inside.

When I do:

cd /Users/simn/Downloads/3D\ World

And then do:

 java -jar 3D\ World.jar

It starts the JVM from that directory and “user.dir” refers to that directory. :smiley: (I feel so stupid now).

I only get an error saying that the shader version 330 is not supported, did you forget to create the display with the core profile enabled?

#15

When I create the display with core profile enabled (version 3.2), I just get a blank screen.

#16

Hmm, that could be anything… :stuck_out_tongue:

Try to make a small OpenGL application and see if it works, it’s for sure a small problem somewhere.

#17

Simn, what OpenGL version do you have? This application requires V3.3

#18

I have support for 4.1 and minor.

#19

Okay Simn, I got core profile enabled. Apparently you can’t call glEnable(GL_TEXTURE_2D) :stuck_out_tongue: Hopefully it works this time.

[Version 0.0.2.4]
-Reorganized engine so it is loading correct natives
-Core profile enabled with opengl version 3.3

#20

Same errors. I would suggest the following:

  • Start over on the .jar file
  • Use a fat .jar creator
  • Profit
