I’m a big fan of writeable bitmaps.
When drawing more then 1000 items on screen writeable bitmaps performs a zillion times better then individual objects.
Based on WriteableBitmap Class MSDN sample it’s peanuts creating a fullscreen drawing application.
After modifying DirectionalBlur shader from the WPFFX I got the this little drawing app.
The above demo was done on a MSI windtop touchscreen (dual core 1.5Ghz Atom CPU)
Use M to (de)activate the mouse.
Use F to toggle fullscreen.
Use ESC to exit the application.



Hi, Nice sample!
I am also looking into writeablebitmaps/pixel shaders to perform really high intensive graphic effects, but Im a bit in-experienced, do you think you could send me the source code for this just so I can have a look at how you go about doing this?
Thanks
Mark
I didn’t publish the code because it’s kinda messy.
But I did send you the source code link through mail.
Have fun with the shaders.
