Minecraft terrain generation really happens at two different levels – the individual “chunk”, and the wider world as a whole. It’s kind of like a jigsaw puzzle – the chunks that make up the world are the individual puzzle pieces, and it’s only when they all come together that you begin to see a complete picture.
Border block is water as well, sand will generate. Floating: World generates in rings of floating islands high in the air. Border block is water. Sand is common although caves often lead into the void. Flat: world is a perfectly flat plane with trees growing. Border block …
You can use 3D perlin noise with an altitude-dependent threshold value to generate cliffs, caves, etc. (Edit – in fact, I see from the link in the answer that is exactly what Notch was doing at one point.) \$\endgroup\$
Custom world generation allows data packs to change how the world/biomes generates. This is particularly useful in conjunction with custom worlds/biomes. Noise settings are for generating the shape of the terrain, stored as JSON files within a data pack in the path data/
It is composed of 16x16x16 chunks which are 16x16x16 cubes. 4096 cubes per chunk, 4096 chunks per region. An algorithm determines which faces of the cubes are visible and adds them to a vertex buffer. Only chunks within view are built. To generate an endless world chunks are recycled and built as you move.

How does Minecraft generate chunks of the world?
The world is generated as needed and only the areas that are generated are saved. This means you are only saving a handful of chunks. A chunk in Minecraft is an area 16 x 16 x world height blocks in size (currently 65536 blocks, previously 32768). Show activity on this post. The entire world is generated using seed values.
What’s new in World generation for Minecraft?
Added water and lava to world generation. Bedrock now generates around the sides and bottom of the map. Terrain now generates in islands above sea level. Some worlds can be 95% water because of this. All dirt with access to sunlight below sea level will not become grass upon world generation. Dirt generation is now two blocks thick.
What happened to the world in Minecraft?
The world no longer generates in islands, but instead, generates lakes within the main land mass, sometimes connecting to the infinite ocean around the world. Worlds were huge in size (512*512). Lava now no longer generates on the surface.
What are the biggest changes to the world in Minecraft?
Dirt generation is now two blocks thick. Terrain generation changed, terrain is now a little smoother than earlier. The world no longer generates in islands, but instead, generates lakes within the main land mass, sometimes connecting to the infinite ocean around the world. Worlds were huge in size (512*512).
