structural colors HD

Explanation
With this experimental application you can see structural color
by tipping iPhone with gyroscope.
Structural color means color which changes with directions of
objects or perspectives like CD or jewel beetle.
This application achieves visualizing structural color by calculating the direction of
iPhone with gyroscope and simulating optic interference.
This applicaion works only iPad2 generation or later.

How to use
Press the upper botton;
1 and 2: interference in the case of diffraction grating.(parameter is grid space)
3 and 4: interference in the case of thin film.(parameter is thickness of film)
