Example Embodiment
[0045] Example 1
[0046] The embodiment of the present invention provides a three-dimensional visual simulation method for simulating driving, see figure 1 , The method includes:
[0047] Step 101: Load a three-dimensional scene model of the train traveling along the track.
[0048] The running screen of the user driving the train is refreshed at a fixed frequency. Each refresh includes:
[0049] Step 102: Correspondingly update the three-dimensional scene model according to the scene state input signal;
[0050] This includes correspondingly updating the signal state in the three-dimensional scene model according to the signal state input signal;
[0051] Step 103: Calculate the user's current point of view and perspective in the three-dimensional scene model according to the input signal of the motion state of the train;
[0052] Step 104: Combine the updated three-dimensional scene model and the viewpoint and perspective to refresh the running picture of the user driving the train tha...
