Comment Feed for Channel 9 - Graphics improvements in WPF 4 http://ecn.channel9.msdn.com/o9/previewImages/100/501662_100x75.jpg Channel 9 - Graphics improvements in WPF 4 David Teitlebaum and Jaime Rodriguez discuss the graphics improvements in .NET 4. David demoes cached composition, pixel shaders 3, and animation easing functions. He also explains discusses rounding, and ClearType Hint. Related resources: Post for this series includes all the new features in WPF 4.  David's and Tim's demos Note: the graphics are fast, we captured screen on software and it did not keep up, that is why the horribly sloooow(yawn) refresh rate on the demos. Try the demos, if you have .NET 4 beta2. en Wed, 19 Jun 2013 20:32:28 GMT Wed, 19 Jun 2013 20:32:28 GMT Rev9 Re: Graphics improvements in WPF 4 There's a big problem with this video. All the screencaptures have very low framerate so during the demos of framerate improvements you can't even tell there's been an improvement.

Agree that the screen captures are horrible.  Our hardware-based screen capture was broken and doing it in software did not work.

If you are running  beta2, you can download the samples and see the benefits.   We will try to re-record the demo soon.

 

Thanks!

Whilst screencaps are better if you're showing code samples which need to be readable, I think it's overkill for the "here's a resizing purple box" type of thing.

 

Got to be said though, this stuff looks very useful. I can see it being very helpful at improving performance in a lot of scenarios.

I have VS2010 Beta 2 and .NET Framework Beta 2 installed. Do these samples require a post-Beta 2 .NET, so we can't view them?

 

Thanks

Jaime - can you repost with the beta 2 bindings?

Some thing must be wrong on my side (later build likely); let me get a clean beta2 machine again. Thanks for your patience.

Simply re-download.  I included source for David's samples.  Tim still wanted to clean it up, but his app ran fine on vanilla beta2.  Will keep nagging him to share the shader.
