The invention concerns a method and a system for: (i) producing in a computer processing unit (2) a flow of synthetic images (3), and (ii) tracing a scene (4) by creating visual interactions between the synthetic image flow (3) and at least one video image flow (5).The computer processing unit (2) comprises: a motherboard (7), a graphics board (8) for scene rendering and display (4), including a processor for accelerating 2D/3D processing (9), a work buffer (10) and a texture memory (11), an acquisition means (12) for acquiring in real time video images (13), in a video buffer (14). The specific rendering of the scene (4) is carried out: by recopying the video buffer (14) in a memory zone (10, 11) of the graphics board (8), by tracing the synthetic images (16) in the work buffer (10). |
