In This Tutorial:

·         Template project and simple 3-step instructions to kick start WPF pixel shaders

·         Introduction to Pixel Shaders in WPF

·         Source Code for 3 pixel shaders

·         Links to 2 pixel shader sources on the web

Using Shaders in WPF: The Easy Way

Pixel shaders are a great way to enhance your WPF program in many ways. I show just few of the possibilities here and provide a good framework to start developing your own effects.

3 steps to kick start you with WPF pixel shaders:

1. Install DirectX SDK

2. Download and open the Shader template project from Nikola’s site: https://www.nokola.com/sources/ShaderEffectTemplate.zip

3. Start coding your effect in MyEffect.fx

Next: Read the Beginner’s Presentation to WPF Pixel Shaders

Downloads

Prerequisites: DirectX SDK from Microsoft.com

View the Beginner’s Presentation to WPF Pixel Shaders here: https://blogs.msdn.com/nikola/attachment/8924657.ashx

Download the template project here: https://www.nokola.com/sources/ShaderEffectTemplate.zip

Download these Pixel Shader samples: Twirl UI, Blobs and Lights: https://www.nokola.com/sources/ShaderEffects.zip Note that you have to enable each effect by itself for best view J Just comment out the other 2 effects when playing at the sample.

Check out these 2 cool pixel shader tutorials:

 Hope you like it!

    Hi uditha, I found a response for your question on http://channel9.msdn.com/shows/Continuum/PixelShaderParts/ : "XNA is not compatible with WPF just yet.  Via reflection you can make it work, but with Vista requiring a 9Ex device for performance, you have a hard time getting 100% out of your hardware.  I have documented it on my blog. link: http://jmorrill.hjtcentral.com/Home/tabid/428/EntryID/259/Default.aspx "

    Hi, Thanks for this useful post. What's important about deploying a wpf project which used pixel shader? I mean we should have DirectX on the client? Are we supposed to compile the .fx file on each client too or just we can use the generated .ps file?

    Hi Ali, For deployment you just need DirectX on the client and you can use the generated .ps file without having to recompile it. Nikola

    Hi Ali, I think you might be able to do something with edge detect filters in pixel shader only. Check this out for the filters: http://en.wikipedia.org/wiki/Canny_edge_detector http://www.pages.drexel.edu/~weg22/can_tut.html I haven't done it before, so I don't know if it would work - seems like it should though. Sorry for the late response! I just realized I haven't been receiving blog notification for quite a while...

    Thank you very much, Nikola. This really works (however I had some troubles with russian letters in project directory name - DirectX SDK didnt recompile the shaders). One more question iam interested in: can i use shaders to render into a bitmap (better - to a texture)? I want to use it after as ImageSource. Thanks!
