3D Effects - Easily transform and animate any display object through 3D space while retaining full interactivity.  Fast, lightweight, and native 3D effects make motion that was previously reserved for expert users available to everyone.  Complex effects are simple with APIs that extend what you already know. 
3D效果，可以簡單的製作3D空間效果，我猜也是二個keyframe就可以搞定。

Custom Filters and Effects - Create and share your own portable filters, blend modes, and fills using Adobe Pixel Bender™, the same technology used for many After Effects CS3 filters. Shaders in Flash Player are about 1KB and can be scripted and animated at runtime.
客製化的濾鏡，能使用Adobe Pixel Bender建立效果，再丟給FLASH10使用。檔案更小更快速

Advanced Text Layout - A new, highly flexible text layout engine, co-existing with TextField, enables innovation in creating new text controls by providing low-level access to text offering right-to-left and vertical text layout, plus support for typographic elements like ligatures.
進階文字排版，這個好

Enhanced Drawing API - Runtime drawing is easier and more powerful with re-styleable properties, 3D APIs, and a new way of drawing sophisticated shapes without having to code them line by line. 
API面版。設計師會很喜歡的

Visual Performance Improvements – Applications and videos will run smoother and faster with expanded use of hardware acceleration.  By moving several visual processing tasks to the video card, the CPU is free to do more.
硬體加速，讚啦，

奶伯伯我已安裝了FLASH PLAYER10，有些demo可以看
http://blog.alternativaplatform.com/en/2008/05/16/alternativa-3d-flash-player-10-astro/

下載FLASH PLAYER10和SDK檔，試寫了一個Demo，
DisplayObject在FLASH10,已經有了x,y,z,rotationX,rotationY,rotationZ的屬性
來看一下我製作的demo吧，(需要安裝FLASH PLAYER10)
