如何将四面体树结构复制到 CUDA 设备内存?

If I want to move the below structure TetrahedronStruct to CUDA device memory, how should I proceed?

struct TetrahedronStruct {
  int index;
  int region;
  TriangleFaces Faces[4];
  Vertex Vertices[4];
  struct TetrahedronStruct *adjTetrahedrons[4];
};

typedef struct {
  long double Nx, Ny, Nz;
  long double d;
  Vertex V[3];
} TriangleFaces;

typedef struct {
  long double x, y, z;
} Vertex;

提供了网格细节(节点数、四面体、坐标和区域).树的创建是在 for 循环中完成的.基本上，每个人脸都根据其坐标和相邻关系在树中定位和排列.
