Over the past couple of days (or is it weeks ;)), I have played with tons of tweaks and customizations for the virtualized CoverFlow. I think I finally have a winner from my project’s perspective. Although I can’t share that version, I’ll show you one that is a few days old. It…

That’s what one of my friends suggested. Well, the source is out there on CodePlex . With some tweaks to the Camera angle, Models and animations, it is quite possible to make ElementFlow look like the following: Have a look at the Video , around the 4:00 mark.

The previous post showed how the CoverFlow view was virtualized and had a video that demonstrated scrolling of 10,000 items. A few more enhancements have been added to improve the overall experience. Some of these include: Lot of customizations for animations, camera settings…

The CoverFlow view of iTunes was a big inspiration for me when I started out experimenting with the ElementFlow control. Initially it was used to visualize only a small collection of items (in tens) and this worked perfectly fine. Recently at my company we decided to adopt the…

User Interface auditing is a fundamental requirement when you want to do usability testing and analysis. The auditing process captures user data about how the mouse and keyboard are used. We will stick to Mouse and Keyboard since they are the predominant input devices. Of course…

I finally received the mail from SAMS with the ISBN for my book. So I guess things are getting official !, which also means I can give out a few more details about the book. Let’s start with the title. The book will be called WPF In Depth and is meant for intermediate to…

This is just a weird shader effect I came up with while I was testing something else. The idea is to distort the image by using the component values (R, G, B). The distortion is achieved by shifting the texture co-ordinate with the values stored in the R, G or B component. Once…

This is just a short post on some of the changes that have been checked in. There were couple of people who provided suggestions/tips/feedback on the controls. I have incorporated most of them and will continue to improve in the next release. Thanks to Ricky Ralston, Marlon Grech…

When writing ShaderEffects for WPF, it is always tempting to first test the shader with images. Testing with images instinctively seems easy but there are some caveats to remember. When the ShaderEffect is applied to an Image, the texture information is directly pushed to the…

In my previous post I described a pixel shader technique for distorting images and 2D textures. The source for this effect is now available on the FluidKit project . If there is enough interest I can do a quick tutorial on how the effect was created.
