in practical applications, when the number of cameras in the target movie block is 2 or more than 2, if the user wants to view an animation scene captured by another camera, but does not know which camera the user wants to view, or wants to view an animation scene captured by any one camera except the first camera, a second switching instruction for randomly switching the cameras may be sent to the terminal, and the terminal may receive the second switching instruction sent by the user.
316. Switching from the first camera to a second camera according to the second switching instruction;
after the terminal acquires the second switching instruction, because the second switching instruction does not carry the unique identifier of the camera, the terminal randomly acquires the second camera from the camera information of the target movie block and switches from the first camera to the second camera, wherein the second camera is a camera different from the first camera.
317. Acquiring a fifth image of the animation scene played by the second camera;
after the terminal is switched to the second camera, a fifth image of the animation scene shot by the second camera can be acquired.
318. Rendering the fifth image to obtain a fifth three-dimensional display image;
after the terminal acquires the fifth image, the terminal may render the fifth image, so as to obtain a fifth stereoscopic display image. The fifth image shot by the second camera is a 2D plane image, the terminal needs to render the fifth image into a stereoscopic display image to present a 3D effect, and therefore the terminal renders the fifth image into a fifth stereoscopic display image.
319. Displaying the fifth stereoscopic display image through the display;
in practical applications, after the terminal obtains the fifth stereoscopic display image, the fifth stereoscopic display image may be displayed through the display, and at this time, the user wears the 3D glasses adapted to the fifth stereoscopic display image, so that the user can view the 3D effect presented by the fifth stereoscopic display image displayed by the display.
In this embodiment, after the terminal receives the second switching instruction, because the second switching instruction does not carry any unique identifier of the camera, the terminal randomly acquires the second camera from the camera information of the target movie block, switches from the first camera to the second camera, acquires a fifth image of the animation scene captured by the second camera, and renders the fifth image into a fifth stereoscopic display image for display, so that the user can view the animation scene with the 3D effect from the view angle of the random camera (i.e., the second camera).
320. Receiving a third transformation instruction of the user;
in practical applications, when a user wants to view an animation scene from different perspectives of a target camera, a third transformation instruction may be sent to the terminal, where the third transformation instruction carries transformation information of a second camera to transform the perspectives of the second camera, and then view the animation scene from the transformed perspectives. The terminal may receive a third transformation instruction sent by the user.
321. According to the third transformation instruction, transforming the orientation of the second camera to obtain a sixth image of the animation scene played by the second camera;
since the third transformation instruction carries transformation information of the second camera, the terminal can transform the orientation of the second camera according to the transformation information of the second camera in the third transformation instruction, and then obtain a sixth image of the animation scene shot by the second camera. The sixth image is an image captured by the second camera during any frame of the process of changing the orientation of the second camera by the terminal, for example, 100 frames are total during the process of changing the orientation of the second camera, and then the sixth image is an image of any frame of the 100 frames. Namely, the terminal obtains the sixth image in a real-time acquisition mode.
322. Rendering the sixth image to obtain a sixth stereoscopic display image;
after the terminal acquires the sixth image in real time, the sixth image can be rendered, so that a sixth stereoscopic display image is acquired, and the sixth stereoscopic display image is rendered in real time. The sixth image captured by the second camera is a 2D plane image, and the terminal needs to render the sixth image into a stereoscopic display image to display a 3D effect, so the terminal renders the sixth image into a sixth stereoscopic display image.
323. Displaying the sixth stereoscopic display image through the display.
The terminal can display the sixth stereoscopic display image through the display, and the sixth stereoscopic display image is rendered in real time, so that the user can wear the 3D glasses matched with the sixth stereoscopic display image, and can view the 3D effect displayed by the sixth stereoscopic display image displayed by the display in real time.
In this embodiment, the terminal renders each frame of image in the process of changing the orientation of the second camera in real time to obtain and display the sixth stereoscopic display image, so that the user can view the animation scene with the 3D effect from different viewing angles of the second camera.
