#35 Force Field Shield

Hexagonal energy shield with Fresnel glow

The hexagonal force field is iconic in sci-fi games. This shader renders a shield as a circle with a hex grid overlaid on its surface. A Fresnel effect brightens edges more than the center, mimicking transparent material behavior. Hex cells pulse with flowing energy, and an animated impact highlight with rippling waves simulates contact on the shield surface.
