What this project is: A 3D sandbox built to learn and apply systems I hadn't worked with before — procedural generation, real-time shader programming, and performance optimization. No menus, no win condition — just the systems.

Fire system: Fire spreads through a collision-based volume that grows over time. When it overlaps a flammable object, two custom GLSL shaders activate on that object — one simulating active fire, one simulating surface burn progression. No grid required; the system works on arbitrary geometry.

Procedural buildings: Buildings are generated at runtime using ordered floor arrays and height sampling to determine where each floor gets placed. Generation runs in O(n) — the scene is never pre-authored.

Optimization: Shader performance was profiled using Godot's built-in debugger, monitoring frame pacing and draw call counts. Recursive scene traversal was used to resolve nested objects while keeping complexity linear.
