  • 3D-RENDERING METHOD AND DEVICE FOR LOGICAL WINDOW
    Publication number: 20140225894
    Abstract: A 3D-rendering method for a logical window is provided, including: drawing a 2D image of a target logical window; projecting the 2D image into a preset 3D coordinate space with aspect ratio of the 2D image being maintained, to obtain a 3D model of the target logical window; performing, in the preset 3D coordinate space, a 3D transformation on the 3D model of the target logical window; acquiring a correcting coordinate value and a correcting ratio value of the 3D model; and perspectively projecting the 3D model after the 3D transformation in the preset 3D coordinate space into a target projection plane. A 3D-rendering device is further provided.
