# Simple Meshes
# Simple Meshes - 간단한 메쉬
A [`mesh`](https://www.khronos.org/registry/glTF/specs/2.0/glTF-2.0.html#reference-mesh) represents a geometric object that appears in a scene. An example of a `mesh` has already been shown in the [minimal glTF file](gltfTutorial_003_MinimalGltfFile.md). This example had a single `mesh` attached to a single `node`, and the mesh consisted of a single [`mesh.primitive`](https://www.khronos.org/registry/glTF/specs/2.0/glTF-2.0.html#reference-mesh-primitive) that contained only a single attribute—namely, the attribute for the vertex positions. But usually, the mesh primitives will contain more attributes. These attributes may, for example, be the vertex normals or texture coordinates.

[`mesh`](https://www.khronos.org/registry/glTF/specs/2.0/glTF-2.0.html#reference-mesh)는 장면에 표시될 기하 물체를 나타낸다. `mesh`의 간단한 예는 이미 [minimal glTF file](gltfTutorial_003_MinimalGltfFile.md)에서 살펴보았다. 이 예제에는 하나의 `mesh`가 하나의 `node`에 첨부되었고, 메쉬는 단 하나의 [`mesh.primitive`](https://www.khronos.org/registry/glTF/specs/2.0/glTF-2.0.html#reference-mesh-primitive)로 구성되어 있어 단 하나의 속성 - 버텍스 좌표만을 갖고 있다. 하지만 일반적으로는, 메쉬 프리미티브는 좀 더 많은 속성을 갖는다. 이들 속성에는 예를 들면, 버텍스의 법선 벡터나 텍스처 좌표 등이 포함될 수 있다.
The following is a glTF asset that contains a simple mesh with multiple attributes, which will serve as the basis for explaining the related concepts:

In addition to the `"POSITION"` attribute, it has a `"NORMAL"` attribute. This refers to the `accessor` object that provides the vertex normals, as described in the [Buffers, BufferViews, and Accessors](gltfTutorial_005_BuffersBufferViewsAccessors.md) section.

As can be seen in Image 8a, the mesh is rendered *twice*. This is accomplished by attaching the mesh to two different nodes:

The `mesh` property of each node refers to the mesh that is attached to the node, using the index of the mesh. One of the nodes has a `translation` that causes the attached mesh to be rendered at a different position.

각 노드의 `mesh` 속성은 메쉬를 참조하여, 노드에 첨부하게 된다. 이때 메쉬의 인덱스를 사용한다. 두 노드 중 하나의 노드는 `translation` 속성을 갖고 있어 렌더링 결과를 보면 다른 위치에 표시된 볼 수 있다.
