Heightmap

A heightmap is like a map of a pretend world, like a map of a video game. But instead of showing the roads and buildings, it shows how high or low each part of the world is. Think of it like a cake that has ups and downs on the top.

When you play a video game that has mountains or valleys or hills, it is made using a heightmap. The game uses the heightmap to know how tall each part of the world should be. It's like the game can feel the cake and know which parts are high and which are low.

So, if you were making your own video game, you would need to create a heightmap first. You can draw it on a piece of paper, or use a computer program to make it. Once the heightmap is ready, you can use it to create your own world with mountains, valleys, hills, and other cool things!
