Phong Interpolation

• Developed two lighting models—headlights and world light—computed using **Phong interpolation** in the fragment shader.
  • Implemented **fragment-based lighting calculations**, combining the **headlight and world light contributions** to determine final illumination.
  • Computed **headlight intensity** by calculating the **dot product of the world object normal and the headlight vector**:
    • World object normal: Normalized value of the object’s orientation relative to world space.
    • Headlight vector: Directional vector from the headlight position to the world-space position of the object.
  • Applied a similar approach to compute **world light contributions**, ensuring realistic lighting effects across dynamic surfaces.
  
• Procedurally manipulated models and textures at the CPU level, generating dynamic surface deformations.
  • Created a **warped surface effect** using a **sin function**, dynamically modifying the X and Y UV coordinates of the plane mesh per frame.
  • Generated a **ripple effect** propagating across the surface, achieved through **algorithmic UV distortion and real-time vertex displacement**.
  

HL/SL Programming

• Developed custom shaders using **vertex and fragment shaders** to enhance visual fidelity and dynamic scene rendering.
  • Implemented **a grid shader** by alternating lighting on the object's **UV coordinates**, creating a structured visual effect.
  • Optimized shader performance by leveraging **vertex-level transformations** to ensure efficient real-time rendering.
