Assignment 3: Lighting and Shading

This homework focused on illumination and shading on terrain meshes. I used index buffers for geometry, computed and transformed normals, added a normal-visualization mode, and implemented per-pixel Phong shading in fragment shaders.

Implemented Results

• Terrain loading from image and BSQ files
• Indexed mesh rendering with averaged per-vertex normals
• Normal coloring mode for debugging
• Phong shading with ambient, diffuse, and specular terms
• Directional and point-light interaction controls
