Hi,

not a game - just a little effect as an applet.
Source is also available - so maybe someone find it useful:

http://labs.weltenkonstrukteur.de/grassveins

Requires Java RTE1.6.

Greetings,
benny!

@zammbi:
Thanks. Glad you like it.

@CommanderKeith:
Thanks for reporting. Strangely, I got this error before several
times. But after clearing my cache and restarting browser I never
got this error again ? I also browsed google concerning this error -
but didnt come to a solution.

Hmmm … that’s really strange - anyone can give a hint ?

#5

pretty cool!

(maybe you could provide it as screen saver https://jdic.dev.java.net/documentation/incubator/screensaver/ ;))

#6

screen saver is a good idea, maybe let the music be parametrizable

#7

Thanks for the nice words - glad you like it.

@bienator:
Wow … what a cool link. Never heard about that screensaver project
before. Really interesting. Thanks a lot for sharing!

Got this in Opera running java 1.6.0_05-b13:
Exception in thread “Thread-47” java.lang.NoClassDefFoundError: Could not initialize class javax.imageio.ImageIO

Runs fine in IE. Nice effect.

#9

Thanks for reporting. Strange ? If it runs on IE - does this mean that it is an error
in Opera ? Anyone can help ?

@zammbi:

Thanks for the error reporting. This is really strange.
Seems that javamod causes that error.

Could you try this applet please:

http://labs.weltenkonstrukteur.de/sketchycube

I used another player in here (MicroMod replay routine).

#12

Yep works well, though so did this one at first ???

#13

None-reproducable error - I hate them >:(
Thanks anyway for testing and reporting!

#14

Just cleared my cache and reloaded it, now works fine :persecutioncomplex:

Hi Benny,

Do you think this program of yours could be used to make textures of unlimited size which look similar to these? :

http://www.cgtextures.com/textures.php?t=browse&q=124

I’m looking for a way to get cool-looking terrain for my top-down view game. I don’t want to use pre-made textures because I can’t get them to look good when tiled since the edges are so obvious. I was thinking that I could use your code to make a big image which is rendered when the level is loaded.

There are more textures on this site, which was linked to by a JGO’er: http://www.cgtextures.com/

Cheers,
Keith

@CommanderKeith:

Hmm … interesting questions. When looking at the following picture,
e.g. :

I could imagine that it would be possible. You could play with the
following:

1.) Create a noise pattern with “sandy” colors. Then you might
end up with something similar to the above image.

2.) Then use my Vein code to simulate the “cracks” in the earth
using black color. If you modifiy this a bit with random starting
position etc. - this might end up in an interesting texture.

Feel free to try it and post some examples if you are done. Interesting
idea.

Good luck :wink:
