Terrain rendering

Ok kiddo, have you ever played a video game where you are running around a world and there are different mountains, forests, and lakes that you can explore? Well, all those different landscapes and areas are what we call "terrain."

Now, when video game makers create these terrains, they need to use a process called "terrain rendering". This means they use special computer programs to create and display all the different aspects of the terrain, like the height of the mountains, the placement of trees, and the color of the sky.

The computer program uses all kinds of fancy math to figure out how to create a 3D model of the terrain. It starts by creating a flat surface and then adding hills and valleys to create different elevations. Then, it adds textures and details like rocks, grass, and water to make it look more realistic.

To make it even cooler, sometimes the terrain rendering can change based on where you are in the game. So, when you climb a mountain, the terrain will change to show you a different view of the landscape.

Overall, terrain rendering is what helps us feel like we are really in the world when we play a video game. We can explore all kinds of different places and feel like we are really there!
