When we set screen->eye in thread of animation displayed 3D-model from another angle even if we call to_screen first.
1. Reset screen->eye in animation thread. : int Animation_5times_thread_011 ( HDC *hdc ) ;
2. Call display-function. : static void paintWindowProc_011( HWND hWnd, HDC* hdc, UINT uMsg, WPARAM wParam, LPARAM lParam, PAINTSTRUCT *ps_001);
3. put vector a little as spin and return to 1.
