Triangle mesh

Imagine you have a bunch of Legos and you want to make a shape, like a triangle. To do this, you need to connect the Legos together with their little pegs. A triangle mesh is like a shape made out of lots of tiny triangles that are all connected together to make a bigger shape.

A triangle mesh is used to create 3D objects in a computer program. The triangles are like the Legos, because they have three points, or corners, that are connected to each other. These points are called vertices. The lines between the vertices are called edges. When you have lots of triangles with lots of vertices and edges all connected together in a certain way, you can make a complex 3D shape like a car or a house.

Sometimes, people use other shapes besides triangles, like squares, to make a mesh. But triangles are used most often because they are simple and predictable. They always have three vertices and three edges, so they fit together nicely in a mesh.

When you create a triangle mesh, you have to be careful to connect the triangles in the right way. If they aren't connected correctly, the object won't look right when you put it in a 3D scene or game.

Overall, a triangle mesh is just a bunch of small triangles connected together to make a bigger 3D shape. It's like building with Legos, but in a computer program!
