Today I want to show how easy it is to produce a basic 3D object in Silverlight, in the below example I have used 5 circles to produce a sphere animation. I treat each circle with a looping Projection Transform.

Each circle is treated with the exact same treatment but offset so that they form a sphere, to break out each circle press the ‘Break Apart‘ button. To fit the circles together again, press the ‘Place Together‘ button.

You can enhance the 3D effect further by pressing the ‘Spin‘ button, this simply plays a storyboard to spin each circle on an additional axis.

To create this effect I have used the Projection Transform Rotation properties and used Easing on the animations inside Expression Blend 3 to help the inertia look right.
