Creating a 3d spiral effect with projection

We can use the projection properties in Silverlight 3 to help produce a 3D spiral animation.

Breakdown of effects

To create this effect I use the following transforms:

  • Opacity at either end of the animation.
  • Projection values to the X and Z axis to make each element loop to the foreground and background.
  • Scale transform to enhance the size of each element at it’s nearest and furthest point.
  • Easing on the above Scale transform to help the movement look more natural.
  • Translate transform to move the elements from the left to right.
