Pixel Shader Effect Examples

Question

I\'ve seen a number of pixel-shader effect examples, stuff like swirl on an image. But I\'m wondering if anyone knows of any examples or tutorials for more practical uses o

Answer 1

One practical thing that pixel shader effects enable ... are blend modes.

Check out Robby Ingebretsen's post on the matter (which discusses a useful way to take advantage of the linear burn blend mode). There is also a StackOverflow question on this subject as well.

In fact, I actually have written a blend mode library for WPF & Silverlight, and make it freely available at my blog. Following is a list of all my blend mode posts (all of which have source code and binaries attached):

• Blend Modes, Part I
• Blend Modes, Part II
• Blend Modes for Silverlight
• Blend Modes, Part III
• Blend Modes: Now Opacity Aware
• Blend Modes: Hue, Saturation, Color, and Luminosity with WPF 4.0

Hope this sparks your imagination ... and let me know if you toy around with the library!
