Tagdox - minimal tag-based document app

  • The app maintains a list of documents, each has a title, body, tags and a timestamp.
  • The documentlist can be confined via tags(pulldown) and/or free-text search.
  • The documentlist can be ordered by title or timestamp.
  • There is functionality to edit,add & delete documents.
  • At startup documentlist is loaded from localStorage or file (JSON format), on change documentlist is saved to localStorage and can be exported to a file.
  • The use case here is a movie collection. The timestamp can be used to store when a movie was watched and to choose which to watch next.
  • The app is quite minimal, it consists of 3 files: data, backgroundimage and source, which has ~11kB vanilla javascript unminified.

Webpage for Hearthstone data log, graph and statistics

The page lets you record results of Hearthstone games. By clicking buttons 'win' or 'loose' an outcome of a game is logged with a timestamp. The resulting game rank is visualized as graph. Data is saved in browsers localStorage and also listed in a textarea (json format). There it can be edited, imported or exported. Finally a win-ratio statistics is available, generated by counting results of each hour of each weekday.

The animation project of a previous blogpost is now extended to a game experiment, with following features:
  • Canvas or WebGl renderer via menu

WebAudio Piano App

Doing some WebAudio experiments. This tutorial helped to start playing music. From there the piano app was implemented, which displays music notes on piano keys. To get music data, a midi-file parser was written, with the help of this format description and the jasmid library. There are 4 different view modes, which are shown on the picture. Replay speed, volume and a replay range can be modified. To start the app, click one of the following links.

►Solaris theme, Bach
►Deception, Winterreise, Schubert
►Silent night


With the carol, since probably there wont be more blogposts in this year, happy holidays and a good transition to 2014 for everyone! :)

Update 10.1.2014: Single tracks can be muted/hidden and screenshot menuitem added.

Wloom 15: bullet.js (and Web 3d editor update)

WebGl game environment 'Wloom' can optionally utilize bullet.js physics libary. This library is now also integrated into the Web 3d editor 'W3dit'. Some thoughts on this version:
  • A first test is a fight game demo (subtitle: High art of low punches).
  • The physics library simulates a physical virtual reality. Another virtual reality layer can be added by using Oculus Rift renderer and device. -> VR²
  • With oculus, canvas hud overlay isnt sufficient anymore, thus a 3d hud with canvas texture is added.
  • In the web editor, press menu 'A.toggle' to see animation and physics.
