There is now an official repository for this: https://github.com/minetest/minetestmapper
Windows downloads are available here.

I rewrote the minetestmapper.py tool to C++. It is at least 50 times faster than original.

Code: Select all

./minetest_mapper ...  6,96s user 0,16s system 99% cpu 7,181 total
python minetestmapper.py ... 531,58s user 1,66s system 99% cpu 8:55,13 total

Source code is on github (https://github.com/mireq/minetest-mapper-cpp).

Required dependencies are:

libgd
boost
sqlite3

Commandline arguments are the same as used in minetestmapper.py

Don't use the "." after "make".

Also, to speed up a large build, use the "-j#" option, where # is the number of cores + 1. My machine has 4 cores so I use "make -j5". To find the number of cores you have, run "grep -c processor /proc/cpuinfo".

Posted: **Wed Aug 29, 2012 21:08**

woah, and c55 added -j2 option permanently in the README for the engine on GitHub... I think he should explain this better...

EDIT: All right, in the -j# the # is number of THREADS and not CORES. So -j2 is for two-threaded one core processor. Menche, you can switch to -j8 then

Nice work, the Win binary worked right off the mark. I noted that I had an odd issue with the .py that didn't happen in the .exe:

.exe on the left, no odd marks like on the right.

Would you be interesting in adding mod color schemes to the colors.txt (if so, see here)?

Posted: **Thu Aug 30, 2012 05:50**

@tonyka: Readme is really missing. README.md will be added in the coming days.

@Menche: In this case, the differences are small:

Code: Select all

make -j 1  7,07s user 0,79s system 98% cpu 7,991 total
make -j 2  7,08s user 0,84s system 121% cpu 6,506 total
make -j 3  7,15s user 0,87s system 135% cpu 5,918 total

@RabbiBob: added, thanks.

Can we have some arguments please?

Here is the contents:

Code: Select all

minetest_mapper.exe -i C:\Documents and Settings\Jordan\Desktop\Minetest 0.4.2\worlds\city\ -o output_file.png

And the world SHOULD work. But it does not generate any .png anywhere.

thank you all, but I have not managed to compile ...
compile and tells me not find GD.h
according to forums related to GD, gives problems in ubuntu, but can not find the solution...

Try one of two things:

Add " around the path

Code: Select all

minetest_mapper.exe -i "C:\Documents and Settings\Jordan\Desktop\Minetest 0.4.2\worlds\city" -o output_file.png

or

Create a util directory at C:\Documents and Settings\Jordan\Desktop\Minetest 0.4.2\
Put minetest_mapper.exe and color.txt in C:\Documents and Settings\Jordan\Desktop\Minetest 0.4.2\util\
Create map.bat and put the following in it:
- minetest_mapper.exe -i ../worlds/city/ -o output.png
Save it and run the bat file

The latter way gives you a quick double click way of running the mapper.

If it only can create heightmaps... can it?

EDIT: greyscale heightmaps.

One question. How to add new blocks to mapping process, ie gloopblocks:cement.

Posted: **Fri Nov 09, 2012 14:21**

I haven't been able to get a rendering of the full map.

Both mappers (python and c++) only generate an area from (+/-) 1472 x (+/-) 1472. I used the "--drawscale" option to confirm this range.

I've been to two, opposite far corners (-30000 to +30000) and built stuff just to make sure something is registered in the world and yet the mapper programs won't extend to that range.

I've checked the "--help" for clues to see if there was some sort of range option or limiter... no luck.

-i/--input <world_path>
-o/--output <output_image.png>
--bgcolor <color>
--scalecolor <color>
--playercolor <color>
--origincolor <color>
--drawscale
--drawplayers
--draworigin
Color format: '#000000'

Any ideas?

where is the default background color set? id like to change it to black i keep forgetting the cmd line argument lol

This is from the minetestmapper "--help" from both the python and c++ versions:

-i/--input <world_path>
-o/--output <output_image.png>
--bgcolor <color>
--scalecolor <color>
--playercolor <color>
--origincolor <color>
--drawscale
--drawplayers
--draworigin
Color format: '#000000'

Perhaps "--bgcolor #000000" is what you are looking for? I haven't tried changing the colors yet to know what happens.

Posted: **Thu Nov 15, 2012 19:03**

i meant change the default in the source code so i dont have to use that argument - cant find what line the defaults' on

Posted: **Tue Nov 20, 2012 03:51**

*bump*

Anyway to expand the minetestmapper's ability to create an image of the full world map (30000+)?
