You can see the Moire interference pattern (red) between two vertical lines (green and blue). You can increase or decrease the pitch (distance between vertical lines) of each of the two sets, and you can change the relative angle between the two sets by changing the angle θ of the 2nd set relative to the first.
Key shortcuts:
- Spacebar to reset (same pitch, no angular offset)
- To change θ: A=increase, S=decrease
Current value θ=0°
- To change green pitch use arrow keys: L=decrease, R=increase
Current value 4
- To change blue pitch use arrow keys: U=decrease, D=increase
Current value 4
