如何在unity中动态创建网格

GameObject gridObject = new GameObject("Grid");

MeshFilter meshFilter = gridObject.AddComponent<MeshFilter>();
MeshRenderer meshRenderer = gridObject.AddComponent<MeshRenderer>();

Mesh mesh = new Mesh();

Vector3[] vertices = new Vector3[] 
{
    // 定义顶点坐标
};

int[] triangles = new int[] 
{
    // 定义三角面索引
};

Vector3[] normals = new Vector3[] 
{
    // 定义法线方向
};

// 设置网格数据
mesh.vertices = vertices;
mesh.triangles = triangles;
mesh.normals = normals;

// 创建网格材质
Material gridMaterial = new Material(Shader.Find("Standard"));

// 设置网格的材质和纹理
meshRenderer.material = gridMaterial;
meshRenderer.material.mainTexture = yourTexture;

// 设置UV坐标
Vector2[] uv = new Vector2[] 
{
    // 定义UV坐标
};

mesh.uv = uv;

meshFilter.mesh = mesh;
mesh.RecalculateBounds();

gridObject.transform.position = yourPosition;
