基于Openmesh8.0版本的带纹理网格文件的读取,请写出示例代码

以下是基于OpenMesh 8.0版本的带纹理网格文件的读取示例代码：

#include <iostream>
#include <OpenMesh/Core/IO/MeshIO.hh>
#include <OpenMesh/Core/Mesh/TriMesh_ArrayKernelT.hh>

struct MyTraits : public OpenMesh::DefaultTraits {
    typedef OpenMesh::Vec3d Point;
    typedef OpenMesh::Vec3d Normal;
    typedef OpenMesh::Vec2d TexCoord2D;
};

typedef OpenMesh::TriMesh_ArrayKernelT<MyTraits> MyMesh;

int main(int argc, char **argv) {
    MyMesh mesh;
    if (!OpenMesh::IO::read_mesh(mesh, "my_mesh.obj")) {
        std::cerr << "Failed to read mesh file!" << std::endl;
        return 1;
    }

    // Check if the mesh has texture coordinates
    if (!mesh.has_vertex_texcoords2D()) {
        std::cerr << "Mesh doesn't have texture coordinates!" << std::endl;
        return 1;
    }

    // Read texture coordinates
    if (!OpenMesh::IO::read_texture(mesh, "my_texture.png")) {
        std::cerr << "Failed to read texture file!" << std::endl;
        return 1;
    }

    // Access texture coordinates
    for (MyMesh::VertexIter v_it = mesh.vertices_begin(); v_it != mesh.vertices_end(); ++v_it) {
        MyMesh::TexCoord2D texCoord = mesh.texcoord2D(*v_it);
        std::cout << "Vertex " << *v_it << " has texture coordinates (" << texCoord[0] << ", " << texCoord[1] << ")" << std::endl;
    }

    return 0;
}

注意，上述示例假设网格文件为 OBJ 格式，纹理文件为 PNG 格式。如果你的网格文件和纹理文件格式不同，需要相应地修改代码。
