Northstar Eyeball-Shaped Infinite Poster Scroller
An innovative, high-performance digital signage poster scroller developed entirely from scratch in Unity 3D and Blender, featuring an eyeball-shaped curved mesh surface powered by a custom multi-texture HLSL offset shader and a $\text{tanh}$-smoothed touch swipe controller.

An unique interactive display installation engineered from scratch to render seamlessly scrolling poster collections along an organic, eye-shaped curved surface without multi-mesh or multi-sprite overhead. The geometry was custom-modeled in Blender as an open-ended, smoothly bended 3D mesh with a rectangular UV layout to maximize texture space efficiency. In Unity, a custom HLSL shader manages five blended texture layers driven by a real-time offset variable, achieving smooth sequential cross-fading and frame transitions. A supporting C# data manager dynamically swaps texture content to support infinite scrolling sequences in both directions, while a robust touch input controller utilizes hyperbolic tangent ($\text{tanh}$) mathematical functions to ensure organic, momentum-based drag response that smoothly approaches and holds at the threshold limits for fluid left-and-right navigation.
