September 15th, 2009Drawing rabbits with WPF pixel shaders
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)
Download the Application
Use M to (de)activate the mouse.
Use F to toggle fullscreen.
Use ESC to exit the application.
