Assignment 2: Triangle Meshes + Transformations

This assignment reconstructed a 3D terrain mesh from grayscale elevation maps (DEM), then rendered and navigated the mesh in WebGL. I implemented model-view transformations for rotate/zoom/pan, height scaling, projection switching, and wireframe mode.

Implemented Results

• DEM-to-mesh conversion with one vertex per pixel and triangle connectivity
• Perspective and orthographic projections
• Interactive rotation, zoom, and panning
• Height scaling and wireframe toggle
