Joe Stegman – Group Program Manager

Glboal notes:

• Agenda talking about the Core Runtime.
• Business libraries, Tooling and other core concepts being presented in other sessions.
• Improved XAP compression built into the tools. 10 to 30% reduction in XAP size. Blend Bits available today.

Meeting notes

• GPU Acceleration – quick tour, several other talks on media
• Perspective 3D – put 2D objects in 3D space.
• Animation Easing – Add it into a “perspective plane” <PlaneProjecton x:name=”P3”  rotationY=”-30”> around media element </>
  • UI to UI binding !!
  • EasingFunction – smoothness of animations
  • exported to excel looks easier.
• Effects and Pixel Shaders
  • Effects
    • impact visual behavior
    • sl3 supports drop shadow and blur
  • SL3 supports cusom effects
    • cusom effects are implemented as shaders
    • shaders typically authored using HLSL
      • compiled into byte code using a DX SDK utility
      • SL3 consumes the byte codes
    • shaders allow developers to modify each pixel on a UI element before the pixel is rendered
    • shader = a per-pixel function or operation
• Pixel APIs
  • Dynamic bitmap generation
    • read/write pixels in a bitmap
  • render a visual tree (elements) to a bitmap
• Scenarios
  • Dynamic image generations for ex RT graphs
  • Image editing and effects
  • clone visual
• Raw Audio
  • similar to pixel API’s but for audio / video
  • Scenarios
    • dynamic sound generation
    • custom audio/video decoders

DEMO

• Played video created multiple snapshots of video on a mouse click
• Demoed DropShadow effect
• Shaders and effects

LOCAL MESSAGING

  • Multiple plugin on same page, different browser tabs, different browsers
• Implementation
