Animate a static image based on Malus' Law of Polarization.
I’m inspired by Barrier Grid Animation, which create illusion of motion based on the occlusion of light and phenomenon of persistence of vision.
The key concept here is selective visibility—revealing only certain parts of each frame at a time. I want to use light polarization to achieve this selective visibility effect.
Collect a series of images with transparent backgrounds. (The following images are provided by @Sai)
Next, divide the area into equal sectors. Each sector will display a different frame of the motion. The resulting image sheet is:
Malus’ Law of Polarization is expressed as:
I = I₀ cos²θ
Where:
- I is the intensity of polarized light after passing through the polarizer.
- I₀ is the initial intensity of the light.
- θ is the angle between the light's polarization direction and the axis of the polarizer.
