MapViewer - not a plugin but a standalone tool

  • well, I try one export on widest zoom : it shows 6 squares biomes, the image is a 20480x12288 pixel and weight 205mo. a whole big map would be difficult to manipulate I think ?

    Well, I tried to make the map viewer as large as possible that it bothers me how the map is the same size as the one in game... Well, not exactly, but similar with how "sectioned" it is that it kinda defeats the purpose. Whatever resolution you have the java viewer is what you get out of the map that whatever you see is what you render. I don't know how the java side handles, but it is a nice out-of-game tool. It's handy, yet needs to render it whole. I can wait out however long it needs to render a whole map.


    I want to be 100% clear that I'm not trying to ruin anything. Not trying to knock on the guy who created the tool that I do find it awesome that we can now view maps outside of the game to then share it in .png manner. That's awesome :thumbup: I respect you guys for finally tackling something we all wished for. More power to you guys!


    I'm used to (spoiled) messing around with various Minecraft map viewing tools that I miss the Isometric tool I used to map out my Minecraft worlds. Same with the Google Map variations where it would render the whole explored map side of things. Whatever you explored it would render it whole. I wish we could get that for Rising World so we could see what we have, how to expand, among other things. I do hope it's possible, and if not we'll wait for when Rising World gains the awesome terrain generator upgrade update.


    I'll try and use the current tool to the limit until something else is done. Again, no ill will to the map creator. Awesome stuff that I'll view it as a necessary baby steps. Keep it up! :thumbup:

  • I can wait out however long it needs to render a whole map.

    It's not the rendering time that's the issue. The application can render the whole map. The problem is there are no viewers that can open up such a large file that the application generates. This is why the in-game map, as well as every map application out there (including Google Maps and Bing Maps) use separate images and stitch them together as your scroll around the map. A principle called Map Tiles. https://en.wikipedia.org/wiki/Tiled_web_map


    There will be a way to process larger maps and compress them into a smaller image, but believe me that process is extremely complex and requires a lot of in-depth knowledge in computer graphics. Looking at each pixel one-by-one and looking at its neighbouring pixels and then generating a new pixel map. And it always results in data loss.


    That's the big problem with image compression.


    Here's an 'a', its pixels as displayed on a screen, and finally the data structure behind it. If you visit each pixel and analyse its neighbours and recreate a smaller file (to reduce the pixel dimensions from 12x14 to say 6x7) then you actually end up with just a mess of pixels and the "information" (in this case the character 'a') will be lost. Same principle with the maps in Rising World, just on a larger scale.


  • Version 0.0.2 - now scaled down output of the complete map possible


    Hi all, i added the option to export a png of the complete map, but scaled down dynamically. This means, when you press the command 'm', a map with the following scale will be created:


    Dimension in maptilesscalepng in pixels
    up to 80 * 801:1up to 20480*20480
    up to 160 * 1601:2up to 20480*20480
    up to 320 * 3201:4up to 20480*20480
    up to 640 * 6401:8up to 20480*20480
    up to 1280 * 12801:16up to 20480*20480
    up to 2560 * 25601:32up to 20480*20480



    and so on, but i think you won't recognize anything if you go above that size. Even at scale 1:32 is very ambitious to find anything on the map, but for those who have such a big map it is possible to create an image of their world...


    Download is here: mapViewer.zip
    To install you will need to proceed just as with version 1; if you have already installed version 1 you will need to replace mapviewer-0.0.1.jar with mapviewer-0.0.2.jar. Starting the program is unchanged.
    Have fun

    • @keitha7373 what do you mean by ‚click on a map‘? The program doesn‘t respond to mouse clicks, it only recognizes a few key presses (as explained above). Can you see a map ingame (by pressing M)? If no, then you need to craft a map first and explore a part of the world. After that you can use my program to view a bigger part of the map on screen or export a png.

    I see, the world i was using to try it out i had not yet created a map - my bad. Thanks. Works on Windows 10 perfectly. Nice Work!

  • Tbh i didn't know where to upload it back then either as it is no mod and no plugin and randomly chose the mods section. I will ask red if we can have a new standalone tool section or else a subsection under mods.
