Effect Library posted

Troy Jefferson interned this summer with the WPF team and gathered a bunch of Effects that had been written by members of the WPF team.  These are now available for downloading on CodePlex.  At that same site, you can also browse to a video of these effects in action. The single input effects in this…

A More Useful Multi-Input Effect

In my last post, I introduced multi-input effects, where you can send in arbitrary WPF brushes that are interpreted as samplers in the shader.  The example I did just showed simple image combination via linear combination of pixel values — illustrative, but not very useful. In this post, I’m going to demonstrate a more useful…

Introducing Multi-Input Shader Effects

Thus far in this series on Effects, we’ve discussed building and using Effects that have a single “texture” or “sampler” as input to them.  In the Beta of .NET 3.5 SP1, that’s all that was available.  With the RTM release, we’ve added the ability to provide multiple samplers as input to the pixel shaders that…

A VisualStudio BuildTask and project and item templates for writing ShaderEffects

In a number of places in this series on Effects, I’ve alluded to a VisualStudio BuildTask and project templates that ease the authoring of shader-based Effects.  We now have one up and available for you to download, install, and use.  This was written by Gerhard Schneider and me.  (Gerhard is the development lead who’s team…

Writing custom Effects – adding parameters to Effects

A couple of posts ago, I wrote about writing custom Effects.  The example that I dove into was ColorComplementEffect, an Effect that has no parameters other than the incoming "sampler" that it inverts the color on. This post is going to go into what it takes to add parameters to your Effects, which allows for…

A simple Effect sample project and ClickOnce application

The previous post in this series began to talk about writing custom Effects for WPF.  We looked specifically at ColorComplementEffect, an effect with no parameters.  In upcoming posts, we’ll get into the details of multi-parameter effects and other specifics.  But in the meantime, I thought it would be useful to post a sample VS project…

Writing custom GPU-based Effects for WPF

The last few posts in this series on Effects have focused on the perspective of those using Effects.  These Effects have to come into being somehow, and that’s where we turn to now.  In this post we showed how to apply a ColorComplementEffect to go from this to this:   ColorComplementEffect, which very much looks…

More details on how Effects work

The last couple posts in this series have dug into features and example usage of Effects in WPF. Let’s go into some other aspects of the feature that are important to understand. Software Rendering When we discuss Effects, we typically talk about them being GPU-accelerated. This is typically the case. However, there are three important…
