Hello mapsters!

Read the new summary page: http://toolchain.eu/minecraft/c10t/

Source is available at Github.

Binary Snapshots

• All Supported Platforms

If you want to try out a graphical interface in development, download one of the jars in:
http://toolchain.eu/.../view/c10t-gui/

Note: MAC users need to add '-XstartOnFirstThread' as a java option when running the jar, otherwise the gui will not run properly, if I ever get my hands on a MAC building environment i will build ApplicationStubs for this instead.

Issues

• Issues should be posted on <!-- m -->http://github.com/udoprog/c10t/issues<!-- m -->
  
• Run the program in debug mode (c10t --debug), this will print useful information, but be much slower.
  
• ALWAYS include c10t --version information when posting issues, that way it can be determined whether the issue already has been resolved or not, if this information is missing, the issue probably cannot be resolved.
  
• ALWAYS include the following information: Platform (e.g. Windows, Linux, Mac) and Architecture (x86, x86_64)
  
• IF POSSIBLE include information which can help us reproduce the problem.

The code that I have explicitly written I grant anyone write too extend, modify or distribute how they see fit, as long as they acknowledge the work of the original contributors.

Also this program is distributed AS IS without any warranty what-so-ever.

Have fun minecrafters!

can it render in the following types?
cave mode
Oblique
Oblique-angled
no water
only render
night/day mode

aaaalso zombuster should take copyrights... im sure you are not allowed to copy a program and mod it

This program evolved from the ZomBuster source, but it's a complete rewrite. I have all respect for ZomBuster and his original creativity, but there was some difficulties with his tool that I wanted to address.

ZomBuster implicitly owns the copyright for his source if he wishes to claim it. But this is silly, i didn't make this tool to earn cash, nor did ZomBuster. I did it because i wanted to have something that does this. Now i want to share it with people.

Off topic / Did you notice how your world resembles (relatively) to west europe ? O_O France, spain/portugal, even a bit of italy on the right xD

[udoprog]

Lol, you are right X D

Don't know if this will help you but I got it to generate the image but it threw out an error...

So here is my log if it will help...

Helped a lot, fix is up on githup, will upload a new snapshot asap

Here is the diff, lol at the typo (width -> height): http://github.com/udoprog/c10t/commit/c ... fe2568dbdf

Thanks alot!

[Guardian9978]

Another thing when I generate the image and use the -i command I get a lot of different black squares...
I tried to compare the black square color(0,0,0,0) to the block list using -l and I cant find it on the list.

Also transparencies would be good. At least for just rendering included and excluded blocks.

[udoprog]

Unassigned blocks are by default transparent now, the other colors are all defined in src/blocks.cpp, which is not complete yet.

[Guardian9978]

Trying to render overhead view with the -a switch and it seems to not render or do anything at all.

This is the command I am trying to use
./c10t -a -w /games/minecraft/world -o /games/minecraft/map-16.png -i 16

[udoprog]

Fixed it, a break statement missing in option scanner. Thanks!

[Guardian9978]

Now if you can fix the black squares showing up when trying to render just 1 block with -i and -a it would be perfect for me.

[udoprog]

I have a fairly good Idea of why the render turns out with black squares, gonna have a look at it in a couple of days.

In the meantime, i've prepared a static windows SNAPSHOT at http://toolchain.eu/minecraft/c10t/c10t ... APSHOT.zip for eager windows users : ).

[ratty]

This kind of thing was so sorely needed, thanks for making this tool.

However, when running it on my server's map, it slowly climbs up to 4G of RAM, while cartographer uses 1.3G on the same map using similar options (oblique, not angled)

$ c10t -w /tmp/world/ -o raw1.png -q -f
(output from top, taken just before it actually starts rendering)
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
12213 minecraf 25 0 3982m 3.9g 476 T 46.6 49.9 5:36.17 c10t

(outdated link removed)


By contrast, cartographer:


$ ( echo 1 ; echo WOb ) | cart5

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
12360 minecraf 25 0 1318m 1.3g 1072 R 99.9 16.3 9:42.96 cart5

(outdated link removed)

My server has tons of RAM so its not a complaint, just pointing it out in case its a bug. 52000 chunks map, its about 14 million square blocks in area.

Also, I'm trying to make a map that actually points north up, so I used -f, but it appeared to have no effect. I have the same problem with cartographer, I just use ImageMagick to rotate it 90 degrees to the right, but its weird having it as if you're to the west, looking east instead of south looking north.

Yes, this was due to poorly optimized image storing with a lot of object overhead. Try again using the linux snapshots which have been updated to use a pure byte array for storing images. This should decrease memory usage significantly.

But for such a huge map as yours, the oblique rendering in it's current state will still take up a lot more memory than what's necessary, you should however se great performance and usage for the top-down rendering.

It's now also possible to flip the image using '-i' or '-r'

Please do note that this is still under heavy development, the snapshots can be extremely unstable if I've screwed something up.

Thanks for the feedback!

Edit: Also, the black materials are laziness on my part, I haven't taken the time to go through all colors, and the image compositioning makes anything colorless black .

There is also the problem with intermediate storage of rendered chunks. If i can pipeline the entire process properly i should be able to half the current memory usage + easily implement multithread (and therefore multicore) support. This will however require two reading phases of the world, but that's not the most expensive operation.

[Guardian9978]

You could modify the color code and have it read the color from a file that way we wouldn't have to recompile it to see the new colors.

I will put that on a Todo, gotta get basic features working properly first : )

[Guardian9978]

Well I hope you can fix the black squares. They're the only thing that's stopping me from writing a php page that overlays the different block types that I chose to make images of on top of the unfiltered image.

[udoprog]

You can write the php page with the black squares still, as soon as I've mapped all the colors and/or give you the ability to do so it will show on the page. The interface (command line switches) will not change in any forseeable future.

[Guardian9978]

So I wrote the php page. The Gold Ore resource is layered on top of the main image without any filtering.

I cut a square out of the image to test transparencies.

http://gmod.zapto.org/minecraft/img.php?res=Gold Ore

These both do the same thing:

http://gmod.zapto.org/minecraft/img.php?res=
http://gmod.zapto.org/minecraft/img.php

So from what I can see the background on the filtered images when generated are white, The black squares are from unset colors, and the actual resource is doted in the white space.
