pzmap2dzi

pzmap2dzi is a command-line tool running on Windows to convert Project Zomboid map data into Deep Zoom format.

Features

• Supports both python 2 and python 3
• HTML viewer for viewing the generated Deep Zoom image.
• Various plant rendering configurations (snow, flower, tree size, etc.).
• Supports multi-thread acceleration
• Supports shared memory acceleration when building dzi pyramid (python 3.8+ only)
• Supports resuming from a breakpoint
• Supports room info rendering
• Supports zombie heatmap rendering
• Supports foraging zones rendering
• Supports isometric view and top view rendering
• Supports map grids in HTML viewer
• Supports map objects rendering (car spawn zones, special zombie spawn zones, map story zones)
• Supports render mod maps as switchable overlay
• Supports save file trimmer to trim local saved games (server mode viewer only)
• Tested with game version 41.78

Requirement

• Storage: The full output size of isometric map for game version 41.78 is around 450GB (or 2.5TB with lossless png format) and consists of 4M files. SSD is recommended as high I/O bandwidth can reduce render time.
• Memory: Each worker requires approximately 1 GB of memory to work. An additional 4 GB of shared memory is needed if the shared memory acceleration is enabled. For example, the program will need 16 GB + 4 GB memory when using 16 threads with shared memory acceleration.
• Time
  • Test machine spec & config
    • CPU: AMD Ryzen 7 5700G @ 3.8 GHz (8 core, 16 threads)
    • Memory: 64GB DDR4 2133
    • Output Storage: NVME SSD
    • Render Settings: 16 thread, shared memory acceleration enabled
    • Game Version: 41.78.16
  • The isometric map rending took around 3.5 hours (or even slower with lossless png format)
  • The zombie heatmap took about half of the isometric map render time
  • If you choose to render only top view map, output size will be around 500MB and can be done within half hour.
• Note
  • Shared memory acceleration
    • May not compatible with Hybrid Architecture CPUs and could result in render failures
    • Unstable with eariler python builds because of buggy implementation. Python 3.10.9+ or 3.11.1+ recommended
    • To turn it on, see Change rendering configurations section below

How to run

1. Install Python

2. Clone or download the project

3. Install requirements

   • If your python version is 2.7, install VCForPython27 first. You can find it here or here

   • run install_requirements.bat

4. Update variables in the config.yaml file

   • Change the pz_root variable to ProjectZomboid game location on your computer
   • Change the output_path variable to the desired output path
   • Change the mod_root variable to steam workshop path if you want to render a mod map
   • Add desired mod maps to mod_maps list (For more infor about how to add mod maps see adding mod maps)
   • See examples for more config details

5. Run the tool

   Run run.bat to render all isometric and top view maps

Change rendering configurations

See conf.yaml and run.bat for more detials.

• Turn on shared memory acceleration

  • In render_conf section of conf.yaml, set enable_cache to ture

• Do not render zombie heatmap

  • Remove arguments zombie zombie_top from run.bat

• Do not render foraging zones

  • Remove arguments foraging foraging_top from run.bat

• Do not render top view map

  • Use run_isometric_only.bat instead of run.bat

• Do not render isometric view map

  • Use run_top_view_only.bat instead of run.bat

How to start the HTML viewer

After the rendering, you get an html folder in your output path.

html
├── base/
├── base_top/
├── foraging/
├── foraging_top/
├── objects/
├── mod_maps/
├── openseadragon/
├── room/
├── zombie/
├── zombie_top/
├─ chrome.bat
├─ chrome_allow_file(need close chrome first).bat
├─ chrome_no_sicurity.bat
├─ pzmap.html
├─ pzmap.js
├─ run_server.bat
├─ server.py
└─ server_config.txt

Directly open pzmap.html will NOT work, as the Cross-Origin Resource Sharing (CORS) Policies will refuse to load Deep Zoom tiles from your locale disk by default.

There are two ways to bypass CORS:

1. Start a server and host your files on your drive
   • run run_server.bat
   • Afterwards, you can open http://localhost:8880/pzmap.html to view the image
2. If you are using Google Chrome with the default install path, you can do one of the followings:
   • open pzmap.html in a standalone tab with all web security disabled.
     • To do this, run chrome_no_sicurity.bat
   • restart Chrome to allow locale HTML access to locale files.
     • To do this, you need close all opening Chrome tabs
     • Then run chrome_allow_file(need close chrome first).bat

How to use the HTML viewer

• To switch floors, use the button form Layer0 to Layer7 on top of the page

• To enable mod maps overlay, use the Mod Map button and then select mod maps

  

• To enable/disable the grid, use the Grid button

  • (Position of the grid will adjust according to the selected layer)

  

• To enable/disable room info, use the Room button

  • (Display room info of the current layer)

  

• To enable/disable zombie heatmap, use the Zombie button

  

• To enable/disable foraging zones, use the Foraging button

  

• To switch between isometric view and top view, use the view switch link

  

• To use Save File Trimmer

  • Edit server_config.txt and set save_path variable to your save folder before start server (The default value is set for Windows 10)
  • The viewer must start in server mode using run_server.bat
