Overview
Skinning refers broadly to the ability to customize the Viewer user interface. The Skinning project is part of the User Interface Roadmap and specifically describes a path to make the Second Life user interface entirely data driven and customizable by Linden Lab, 3rd party developers, and individuals, without requiring changes to the primary application source code, and maintainable across updates.
Priority
See Also
- Skinning HowTo/Basics - documentation on current capabilities
Objectives
- Enable internal designers to more easily customize the look of Second Life
- Enable external developers and residents to better serve their audiences, and save customizations and prepare skin "packages" that persist across viewer updates
- "Skinning" can mean a lot of things. So for this project, skinning shall initially mean:
- A custom look using the same-sized images. (for example, Dazzle)
- Custom floaters that display HTML and can speak back to the client through SLURLS.
- Customizations or language customizations are retained across installs
- "Simpler" skins that allow parts of the UI to be removed
- Customized help links
- Please use the 'discussion' page to raise constructive architecture considerations if you like.
Tasks
Phase 0
- The first phase is to implement Project Dazzle, which is a first skin implementation and proof-of-needed-abstraction for changing the colors/look of the user interface.
- Immediate priority to:
- VWR-5059 Include the ability to change skins and restore the Classic skin
Phase 1 - Widget Cleanup
VWR-6027 Skinning Phase 1
