Nft-Marker-Creator-App

This editor creates NFT markers for WebARKitLib and ARTOOLKIT 5.x, they are compatible with jsartoolkitNFT.js, jsartoolkit5.js, artoolkit5.js, ARnft.js and AR.js. A Node app is provided.

Check out the wiki to learn how to generate good markers! https://github.com/Carnaux/NFT-Marker-Creator/wiki/Creating-good-markers

This project is based on the original NFT Marker Creator by Carnaux but has been updated to work with the latest versions of Node and NPM, and also to work with the latest version of Emscripten, plus other improvements.

Node app

How to use it

1. Clone this repository.

2. Install all dependencies. First run

   nvm install

   it will download the node version specified in the .nvmrc file. You need to install nvm first if you don't have it. Then run nvm use 18 to use the node version specified in the .nvmrc file.

   Then finally run

   npm install

3. Put the image you want inside the src folder. You can just paste it or you can create a folder. e.g

   • NFTmarkerCreatorAppFolder
     • NFTMarkerCreator.js
     • IMAGE.PNG ⬅️
     • ...

   or

   • NFTmarkerCreatorAppFolder
     • NFTMarkerCreator.js
     • FOLDER/IMAGE.PNG ⬅️
     • ...

4. Run it

   node NFTMarkerCreator.js -i PATH/TO/IMAGE

   In the end of the process an "output" folder will be created(if it does not exist) with the marker files.

You can use additional flags with the run command.

e.g node app.js -i image.png -level=4 -min_thresh=8

-zft
      Flag for creating only the zft file
-noConf 
      Disable confirmation after the confidence level
-Demo
      Creates the demo configuration
-level=n
     (n is an integer in range 0 (few) to 4 (many). Default 2.'
-sd_thresh=<sd_thresh>
-max_thresh=<max_thresh>
-min_thresh=<min_thresh>
-leveli=n
     (n is an integer in range 0 (few) to 3 (many). Default 1.'
-feature_density=<feature_density>
-dpi=f: 
      Override embedded JPEG DPI value.
-max_dpi=<max_dpi>
-min_dpi=<min_dpi>
-background
     Run in background, i.e. as daemon detached from controlling terminal. (macOS and Linux only.)
--help -h -?  
      Display this help

5. The generated files will be on the "output" folder.

6. (OPTIONAL) You can test your marker using the demo folder!

   • Just run npm run demo.

   • It should open a server at: http://localhost:3000/

   If you want to create the demo configuration when you create a marker, add -Demo to the command parameters.

   e.g node app.js -i image.png -Demo

Create your NTS markers with our docker image

First, you need docker installed in your system, if you haven't, follow the Docker engine installation instruction . Then inside the folder you want to run docker:

docker run -dit --name nft-app -v "$(pwd):/src" nft-marker-creator-app:0.2.0 bash

With the docker container generate the NFT marker:

docker exec nft-app node ../Nft-Marker-Creator-App/src/NFTMarkerCreator.js -I /src/pinball.jpg

remember to prepend the -I /src/<path to your image>

Build

Build emscripten files with docker:

docker run --rm -v $(pwd):/src -u $(id -u):$(id -g) -e "EMSCRIPTEN=/emsdk/upstream/emscripten"  emscripten/emsdk:3.1.26 npm run build-local

or better create a docker container and run the build command inside it:

docker run -dit --name emscripten-nft-marker-creator-app -v $(pwd):/src emscripten/emsdk:3.1.26 bash
docker exec emscripten-nft-marker-creator-app npm run build-local

Planned Features

• Multi threading support to speed up the creation of the markers.
