I am a Virtual World Developer living in Frankfurt/Main,
playing with OpenSimulator on a Raspberry Pi2
and do some DIY Hardware stuff.

"A walkable 3D map"

The idea for this approach, to develop some kind of OpenSimulator Web-based viewer, emerged by a conversation on the OpenSimulator Educator's Mailinglist

Step One

Wording a Functional Specifications Document (FSD)

  • Utilizing a "3D Snapshot" of an OpenSimulator Region (.oar archive file)
    • Walk through via web browser -> WebGL / three.js
    • Ability to display 3D content (static, No LSL)
    • Movement control and camera control panels.
    • HUD functionality using JavaScript
    • No inventory access
    • No login required
    • Ability to load different teleport locations into a fixed teleport HUD
    • Region map with teleport capability
    • Runs from local install/USB key
    • Settings menu / autodetection draw distance
    • Chat (Text) functionality
    • Open Source licence
  • Please participate!
This is how the web-based viewer will work
Visiting the regions web-based viewer page is showing a window into the '3D Snapshot' region, the size of the window is determined by the performance of the users client. The window is overlayed by a translucent layer showing an opaque button labelled "Start Now!". By clicking the button, a 'CAPTCHA' field appears. Passing the 'Turing test', the translucent layer disappears and the back of an avatar inside the 3D Snapshot is shown. Simultaneously - a 'NPC' avatar 'spawned' inside the dependend simulator - at the regions Landing Point. The user can now operate the avatar. The location of in-simulator avatars can be transmitted into the '3D Snapshot', they are represented by a prim or by a textured mesh. The location of a 3D Snapshot avatar can be represented inside the simulator via NPC. Also shown is a 2D Region map utilizing JavaScript to 'teleport' to another spot. Movement control, camera control panels, the Region map and a settings menu icon are overlaying the scene - but can be folded up. The draw distance can be set manually too. Every X (24) hours a snapshot (.oar) of the current region state is created, which is then converted to a format WebGL/three.js can render. The data of avatar locations can be provided via xml-rpc/UDP. A possibility for text chat on the webpage is given - which can be relayed to the corresponding simulator region, in-world chat can be forwarded to the chat client on the website too.

Collision detection (3D Collision Map)
If (since) the user is operating the in-simulator avatar, the position would be transmitted 'to the 3D Snapshot'. This approach would require that newly rezzed in-simulator objects 'become physical' by the creation of the 3D Snapshot and in-simulator objects are not changing their position.

  • 3D Snapshot
  1. three.js Collision detection
Communication
  • User
  1. IRC Front end » A minimalist Web IRC client
  2. IRC Back end » IRCBridgeModule
  3. WebRTC
Step Two will be

Writing a parser/converter for '.oar' files using python to extract data - which then is used utilizing three.js.
