Dynamic 3d space | Floating Sketches Tutorial

parallax_thumbI’ve had quite a few questions about how to make depth in flash. Earlier (like, 2 years ago) I put up an experiment file to give some interactive depth to some sketchbook sketches, see Floating Sketches. I’ve finally gotten around to translating that into as3. It’s still the same basic idea, Create layers of levels, and have each one respond to the mouse a little differently. The ‘closer’ depths will move faster while the farther away depths will be slower. A simple technique called Parallax.

  1. Seperate the scene into layers
  2. Place the layers in the correct depth
  3. Make closer layers react fast and farther layers slower

//3d created by layers and placing objects on each layer – the layer has it’s own distance, simulated by movement and alpha
