微软透漏DirectX将新增Direct2D和DirectWrite

qrli

详见PDC的视频或者
http://blogs.technet.com/thomasolsen/archive/2008/10/29/introducing-the-microsoft-direct2d-api.aspx

D2D特点：
架在D3D10.1之上的2D矢量绘图API
硬件加速的立即模式，有后背软件模式
便于和GDI/GDI+/D3D交互
和D3D一样要处理设备丢失

DWrite的特点：
在D3D/D2D目标上绘制ClearType文本

诸位觉得如何？

个人觉得D2D现在出来有点鸡肋，没啥新意。
DWrite倒是期待已久的功能了。

Direct2D is built on top of Direct3D 10.1

It does run on Vista; however, before you can do that, you need an updated DXGI. People are discussing how to get this functionality down to Vista (e.g. service pack, etc), but nothing has been decided yet.

We've had D2D running on Windows XP; however, actually distributing it on XP is complicated because all of the components that we're dependent on (Direct3D10, DirectWrite, etc) would also need to go downlevel. Weve had a number of customers asking for XP, but we have limited resources, and our first priority is shipping a high quality Windows 7

q:what about regular D3D10? Since there's no support from Nvidia for D3D10.1, what happens there?
a3D10.1 drivers are a logo requirement for Win7.

.....洗洗睡吧，等普及至少3，4年

ClearType文本是什么文本呢？

在d3d里画flash和flv又慢又费力，我才做了，恶心的很

flash10也支持gpu加速了
d2d干嘛要基于10.1?这月dx11就出了,明年1季度rv870就出了..实在不想再评论xp和vista,微软本想让d3d10给vista长长脸,没想到vista反而拉了d3d10的后腿
ps:好像d3d10已经不会设备丢失了吧,怎么d2d还要处理设备丢失?

D3D10没有设备丢失，但有设备移除，需要做的处理和设备丢失差不多。当时看到这个说明时有种想砍人的冲动 [em22]

flash总归是cpu渲染的，就算渲染到d3d表面也是纯软

从DeviceLost改成DeviceRemove了？？我也想砍人....

矢量图貌似很强大，不知道效率如何。怎么说这些东西都得需要硬件支持，否则就是一个空想
