A high-fidelity WebGL terrain experiment rendering a responsive grass field deformed in real time by an interactive boulder.

Built around a local sphere-collider simulation that feeds world-space coordinate matrices directly into a localized vertex-shader deformer, avoiding expensive CPU-side collision calculations. Ground texturing dynamically blends soil and vegetation using slope-based vertex attributes, while the rendering pipeline utilizes hierarchical shadow frustum culling to keep physics and interactions latency-free.
