Task Challenge \nted Challenge \nted Achievements Demo Game Terrains Methods Height maps Procedurally Generated

Task Challenge \nted Challenge \nted Achievements Demo Game Terrains Methods Via Geometry Shaders Height maps Procedurally Generated

Task Challenge \nted Challenge \nted Achievements Demo Game Terrains Methods Scanning Models Via Geometry Shaders Height maps Procedurally Generated

Task Challenge \nted Challenge \nted Achievements Demo Game Terrains Methods Drawbacks Heightmaps Lack of complexity in environment (No caves / tunnels) Procedurally Generated Can’t be saved and reused. Gameplay is inconsistent Geometry Shaders Difficulty in collision detection High computational costs Scanning Models Difficult to create Costly in time and resources
