WorldGeneration

My Project

I have always been interested in procedural generation, so I decided to create my own world generator. I use different octaves of Perlin noise to generate, among other things, flatlands, mountains, and forests. It’s been a journey filled with a lot of optimization to reduce lag and increase FPS. I started this project in December 2024 and have been working on it between courses. I am still fascinated by what can be achieved with Perlin noise.

Note: I am not trying to make a ripoff to get something out of it. This is a part of my portfolio as a student and I just want to show what I am able to create.

Meassures taken to optimize performance and create smooth gameplay

• Custom primitive cubes are created instead of using prefabs.
• Faces of blocks inside chunks (not visible) are not rendered.
• Chunks are generated asynchronously.
• Spiral chunk loading pattern.
• Chunks outside the active range are culled (removed).
• Efficient biome blending by using multiple layered perlin noise.
• Density-Based tree spawning.
• When modifying blocks ,  only affected meshes are regenerated, not entire world.
• Block UV coordinates are cached and reused across chunks for texture mapping efficiency.
