摘要： A data processing system (70) for graphics processing, including a scene manager (80). The scene manager (80) includes a scene loader (86) for receiving a description of 3 dimensional objects in a scene from a 3-dimensional modelling tool (46). The description includes first 2-dimensional frame data. The scene manager (80) has a texture image modification unit (84) for receiving second 2-dimensional frame data from a 2-dimensional rendering engine (40), and for replacing the first frame data by the second frame data. The scene manager (80) has an animation scheduler for scheduling and monitoring an animation of the scene. The system includes a display manager (96) operative to invoke the scene manager (80) to render output frames in a display buffer (100), and a scene Tenderer (88) configured for applying the 2-dimensional frame data to the 3-dimensional objects to produce textured 3-dimensional objects in the display buffer (100) and outputting the textured objects in the animation. Related apparatus and methods are also described.
