YCanvas is an open source ActionScript 3 library that provides stage3D (GPU) engine for perfectly overlapping grid based zooming projects like world maps or onBoard or simply a tile maps renderer.

Repository content:

• ApplicationDemo - sources for simpliest YCanvas implementation demonstrating implementation over Open Street Map available live on http://ycanvas.yoz.sk/demo
• ApplicationExplrorer - sources for YCanvas explorer available on http://ycanvas.yoz.sk/explorer
• ApplicationMap - YCanvas maps implementation with Feathers UI available on http://ycanvas.yoz.sk/maps/ (available tiles: ArcGIS Imagery, ArcGIS National Geographic, MapQuest, OpenStreetMap, MapBox, CloudMade, Bing Maps Imagery)
• ApplicationMapMobile - sources for YCanvasMap implementation for mobile application
• ApplicationMarkers - sources for YCanvas explorer available on http://ycanvas.yoz.sk/markers
• ApplicationRemotair - sources for YCanvas with Remotair available on http://ycanvas.yoz.sk/remotair/ . This app lets you remote controll YCanvas application with Remotair. Uses multitouch (two-finger) gestures to move, scale, rotate
• YCanvasLibrary - sources for YCanvas library
• YCanvasMapLibrary - sources for YCanvas map library

You can see Ycanvas explorer demo live on ycanvas.yoz.sk (+stats) to compare the speed of original implementation vs. YCanvas, or browse repository for sources to understand the simplicity of implementation of 3rd party systems:

• onBoard
• Wall Of Fame
• WebCanvas
• MapQuest
• ArcGIS
• Open Street Map
• Flickr - gallery experiment

The engine is optimized for rendering speed as well as for relasing unused system resources. While GPU api for flash player requires textures at width and height at power of two, you can reach the best performance when using 256x256 or 512x512 source images etc.
