Playing with Projection in Silverlight

All Silverlight Examples, Silverlight 3 tutorials, Silverlight Blend Tutorials, Silverlight Effects, by Gavin Wignall.

Using only storyboards and behaviours I have created a cool 3d particle effect.

Break down of effects.

Each element (circle) has it’s own storyboard that uses the projection properties to spin it around in a 360 degree fashion on it’s X axis. By increasing the centre point value of the Z axis we get a larger radius.

On top of that each element is offset by 30 degrees on it’s Y axis, this allows all the elements to form an imaginary sphere. I have also set the storyboard durations to different lengths to allow a chaotic feel to the animation.

Finally I have performed a rotate animation on all of the elements. The was no code needed to create this example, everything was done inside Expression Blend 3.


To take the animation one step further, I have replaced the coloured circles with radial gradients and changed the scale of several elements. This adds an additional dimension to the animation.

  1. Dude,

    Your downloads links don’t work! :(

    Respectfully.

  2. Very interesting! Thanks for giving us the source to tinker with. :)

  3. All fixed, the source links should now work.

  4. Cool stuff! Thank you for giving this exmaple. I think about a fancy loading animation in a Silverlight application with this.

  5. for loading animation this might very big size…

  6. As usual, your examples rock.
