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

• Clone this repository.

• 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

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

  • NFTmarkerCreatorApp Folder
  • NFTMarkerCreator.js
  • IMAGE.PNG :arrow_left:
  • ...

  or

  • NFTmarkerCreatorApp Folder
  • NFTMarkerCreator.js
  • FOLDER/IMAGE.PNG :arrow_left:
  • ...

• Run it

cd src
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 NFTMarkerCreator.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.

• (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 NFTMarkerCreator.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 the docker image:

docker run -dit --name nft-app -v "$(pwd):/src" webarkit/nft-marker-creator-app:0.2.1 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:3.1.69 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:3.1.69 bash
docker exec emscripten-nft-marker-creator-app npm run build-local

In VSCode you can run the setup-docker and build-docker command inside package.json.

Planned Features

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