摘要：
Particular embodiments display an object over a background on a screen of an electronic device; and display a shadow effect for the object on the screen of the electronic device, including simulating a three-dimensional (3D) environment encompassing the object; simulating a light source at a specific position within the simulated 3D environment; simulating a shadow cast by the object on the background as a result of the light source shining on the object in the simulated 3D environment; and rendering the shadow on the screen of the electronic device.
