Minetestmapper rewritten into C++

[wziard]

Sorry, it should be --zoom 4. And it does look a lot nicer with --zoom 4 than scaled with gimp afterwards, because the cubes get a bit bigger.

Oh and 99% of the praise should go to the original writers of minetestmapper for the clear code. I just bolted on some brute force isometric overdrawing :-)

[papou30]

Hello, having tried all the geometries and always having the same result I come to ask for some help because this line always appears: "Exception: Image format not supported by gd" So what is this "gd"??

[wziard]

"Exception: Image format not supported by gd" So what is this "gd"??

gd is the library minetestmapper uses to save images. You need to give a valid extension to the output filename.
For example -o out.png or -o out.jpg I think gd supports jpg, gif and png

[papou30]

A thousand thanks so I can have some "isometric maps". You have done an incredible job. Congratulations and thank you again.

A thousand thanks so I can have some "isometric maps". You have done an incredible job. Congratulations and thank you again.

Thanks for the praise :-). But as I said before, 99% of the work is done by sfan5, mireq, Shadowninja... So the largest part of the praise should go to them :-)

[papou30]

Of course I associate sfan5, mireq, Shadowninja to these thanks.

wziard: I don't manage to compile your iso branch, I get this huge ugly error (sorry if parts of it are in french).

/home/gael/Github/minetestmapper/include/BlockDecoder.h:17:56: error: ‘>>’ should be ‘> >’ within a nested template argument list

I'll look into it. What system do you try to compile on? My first guess would be an incompatible gcc version.

[edit] That was it. It should now compile with gcc v5 or higher (or lower, but I didn't test that).

[wziard]

I added a flag to tune the height shading in isometric mode.

[papou30]

Hello, Gaël I managed to compile from the folder extracted from the "zip" with the latest version of C++ on Ubuntu 18.04.1 LTS. Sorry for the screens but I can't insert the images in the forum, still a beginner despite my age.

[Gael de Sailly]

Hello, Gaël I managed to compile from the folder extracted from the "zip" with the latest version of C++ on Ubuntu 18.04.1 LTS.

Thank you, actually I had already solved my problem but forgotten to reply here :)

[Fixer]

Nice, isometric is very needed

[lilo]

Hi,

i want to use this https://github.com/est31/leaftest to get an zoomable worldmap. This will need this minetestmapper. My question is, what git-repo is the best to do this? I found some forks an i am now a little bit confused what is the right version :)

I will use this on an Ubuntu 18.04 LTS Server, if that's important.

greets

[addi]

https://github.com/adrido/minetest-mapper-cpp is the continueed fork of the Rogier5 version

[wziard]

My fork includes code to set up a leaflet map. This was my main reason to add the --tiled flag.

Use the iso branch from here:
https://github.com/wziard/minetestmapper/tree/iso

edit:<snip example script, I added it to the repository>

I put an example script to generate a leaflet map into the 'leafletmap' subdir.

p.s. it you want an *isometric* leaflet map you'll also need the mergeiso utility to merge the isometric diamond shaped tiles into square tiles as input for the buildpyramid utility.

[ShadMOrdre]

wziard,

I downloaded your iso branch, mainly because I saw a script for generating colors.txt values. I'm using Python 2.7, and I keep getting an error about UTF-8 encoding? I don't know python, or bash, and am at a loss.

Shad

[wziard]

The colors.txt script is not by me, it's from (original) minetestmapper. However, it worked fine on my system I think.

However I can try to help. What system are you using to run it on? And what are the exact errors? Maybe better to send me a PM because it's not really on topic here.

[rubenwardy]

p.s. it you want an *isometric* leaflet map you'll also need the mergeiso utility to merge the isometric diamond shaped tiles into square tiles as input for the buildpyramid utility.

Please may you give an example of this?

Edit: Also, the map that is produced by the generate leaflet script is blured when you zoom in, possibly due to JPEG. The nearest zoom should definitely use PNG

[lilo]

Hi,

i test my minetestmapper compilation an i get some unkown node messages. What is to do?

Greets

EDIT: I found this this to auto create an Color.txt :)

[wziard]

Please may you give an example of this?

I was trying to update my isometric map after my summer holiday, and I noticed I had forgotten how everything works myself. :-D

So clearly better documentation and helper scripts are needed.

I'll try to write up how it works after I've figured it out myself again :-)

Edit: Also, the map that is produced by the generate leaflet script is blurred when you zoom in, possibly due to JPEG. The nearest zoom should definitely use PNG

This probably has nothing to do with jpg vs png, but with zooming in further than level 0. At the default zoom level minetestmapper uses 1 pixel/block. If you zoom in so far that 1 block is more than 1 pixel on your screen your browser will start to interpolate between the pixels.

The solution is to use the --zoom option from minetestmapper to make the blocks somewhat larger. I tend to use '--zoom 4 '. This also leads to nicer isometric maps.

Hi, is there a way to only generate a portion of the map?

I see a pair of min-y / max-y parameter for the y coordinate, but can't find similar parameters for x and z coordinates.

I have a map with a few random emerged areas of near 500 by 500 nodes each and minetestmapper abort with an error because the total map size it want to generate is too big. After checking, the problem is not the map size (the DB file is less than 50MB) but that some of the emerged areas are too far away so there is a lot of not generated areas that minetestmapper needs to include in the PNG file.

From the --help output:

Code: Select all

  --geometry        x:y+w+h

You specify a minimum x and y (y in the output image matches z in the Minetest coordinate system) then a width and height. For instance I have this command line (bash) for rendering a specific city area from a world download:

Code: Select all

minetestmapper -i ~/.minetest/worlds/linuxforks -o banana_place_$(date --iso=d).png --colors mycolors.txt --geometry 512:8400+512+384 --min-y -100 --drawalpha

The bottom left corner is at x=512,z=8400 in the Minetest world and the width x height is 512x384. With some arithmetic, you can convert top right corner coordinates into width and height.
