摘要： The present application discloses method for real-time processing image data based on a rendering engine. The method includes sampling a first set of data in a first pixel arrangement to be displayed as an image in a display screen with pixels in a second pixel arrangement. The method further includes creating a first model mapped with the first set of data to generate a second set of data and a second model mapped with the first set of data to generate a third set of data. Additionally, the method further includes rendering the second set of data using a first shader to output a fourth set of data and rendering the third set of data using a second shader to output a fifth set of data. Furthermore, the method includes superimposing the fourth set of data over the fifth set of data to display a sixth set of data.

摘要： The present application discloses method for generating a panorama image based on a rendering engine associated with a display apparatus. The method includes determining a display model configured to be a polygon prism for a rendering engine corresponding to a panorama view of a scene. Additionally, the method includes using multiple sampling cameras associated with the rendering engine to capture multiple sample sub-images of the panorama view in respective directions towards multiple sub-planes of the polygon prism. The method further includes attaching the multiple sample sub-images to respective multiple sub-planes to form a constructed display model. Furthermore, the method includes rendering the constructed display model by the rendering engine to reconstruct a panorama image and displaying the panorama image on the display apparatus.
