Phil Middlemiss has designed a Scalable Glassy Orb Radio Button Style.

It scales well from small sizes to large so can be used on a toolbar or as a large feature. The button has an attractive glassy style complete with "reflections" and a smooth curved look. Completely vector - no PNGs used for effects.

The new Blood shader works only on skin colors. To use it, you have to use the selection brush to select skin tones from the image.

I read somewhere online that Hue changes can't be done in pixel shader 2.0, due to limitation of 64 instructions per slot. Here's the sample that proves otherwise.

The "Noise" can be used to make effects such as fire, water, marbles, smooth motion, hand-drawn UI, space travel effects, nebulas and a lot more!

Simplex noise has similar characteristics to Perlin noise - it's continuous, smooth and its first derivative is smooth too. The nice thing about the Simplex, is that its much easier to compute and thus can be implemented in Pixel shaders.

Corey Miller demonstrates how to take the result of a PixelShader and write that out to a bitmap.

While this is not the best way to do image calculations in the code behind in terms of imaging with Silverlight and WPF I was perplexed with the problem of having a great pixel shader that I could apply in the xaml using Bitmap Effects but unclear as the best way to translate that to an actual Bitmap Image. If you are looking for a quick fix solution I wanted to share a little gold nugget in how to actually do this that I found. Just to explain a bit more this assumes you already know how to use Pixel Shaders, I will include a sample code to help illustrate this if you do not.

Introduction

Since the first release of Silverlight, the community has been patiently waiting for a version of Silverlight which would allow us to capture video from a user’s webcam, as well as audio from their microphone. This past month at PDC 09, our wait was over with the release of Silverlight 4 Beta 1.

In this article we will explore the ways in which Silverlight can interact with a webcam, as well as the powerful results one can produce by combining live video with pixel shaders, video brushes as well as WriteableBitmaps.

René Schulte has posted this demo which uses the webcam and microphone support and his edge detection pixel shader to create a real time edge detection system in Silverlight.

One of my favorite new features is the webcam and microphone support and I've coded a small demo that uses the new Silverlight 4 CaptureSource class and applied my edge detection pixel shader to it to create a cool real time webcam effect.

Last spring, I blogged about a technique for creating reflections programmatically using WriteableBitmap. For TechEd Europe week after next, I decided to go one step futher and create a pixel shader that does the same. Called WetFloorEffect, my shader can be applied in XAML the same way built-in shaders such as DropShadowEffect and BlurEffect are applied.

Silverlight 3 introduced the ability to use Pixel Shaders with 2 native effects built in and available in the Expression Blend 3 tool. The two Pixel Shaders that Blend currently offers are ‘Drop Shadow‘ and ‘Blur‘. The Drop Shadow effect is even able to convert Photoshop Drop Shadow effects reasonably well through the new ‘Import Adobe Photoshop File‘ feature.

Both the ‘Blur‘ and ‘DropShadow‘ effect will work on any item inside your project, including vector shapes, text and images (even with transparent areas).
