Features Integrated

Procedural Terrain Advanced Water GPU Vegetation Procedural Sky Volumetric Fog Interactive Controls

This demo combines all Strata features into a single cohesive scene:

Procedural Terrain with multiple biomes and height-based materials
Advanced Water with reflections and wave animation
GPU Vegetation covering the terrain hillsides
Procedural Sky with atmospheric scattering
Volumetric Particles for atmosphere and depth
Interactive Controls for exploration
