It allows users to pan around and zoom in a large, high resolution image or a large collection of images. It reduces the time required for initial load by downloading only the region being viewed and or only at the resolution it is displayed at. Subsequent regions are downloaded as the user pans to or zooms into them animations are used to hide any jerkiness in the transition. The libraries are also available in other platforms including Java and http openzoom.org Flash . History The Deep Zoom file format is very similar to the Google Maps image format where images are broken into tiles and then displayed as required. The tiling typically follows a quadtree pattern of increasing resolution of image in other words twice the zoom and twice the resolution . The main difference is that with google maps the actual details on the image change from one zoom level to another, with deep zoom images the same image is displayed at each zoom level. Seadragon Software , formerly Sand Codex, first created the Seadragon technology and its implementation of what is now called Deep Zoom. This technology was then absorbed into the Microsoft Live Labs when Seadragon Software was acquired. Engineers from Seadragon now work with Microsoft to integrate their work into technology such as Silverlight and Photosynth . ref http blogs.msdn.com jaimer archive 2008 03 31 a deepzoom primer explained and coded.aspx Jaime Rodriguez A deepzoom prime ... more details

X3D extension supports multi stage and multi texture render, it also supports shader with lightmap and normalmap. In 2010 X3D supports deferred rendering architecture. Now X3D can import SSAO, CSM and Realtime Environment Reflection Lighting, but doesn t need care much about polygon counts. The user can also use optimizations like BSP QuadTree OctTree or culling in the X3D scene. X3D also benefits from other open source standards like XML, DOM and XPath. The user can easily develop content tools like an exporter and editor which make content creation and optimization tasks eas ... more details
