Abstract. We present work on exploiting modern graphics hardware
towards the real-time production of a textured 3D mesh representation
of a scene observed by a multicamera system. The employed computa-
tional infrastructure consists of a network of four PC workstations each
of which is connected to a pair of cameras. One of the PCs is equipped
with a GPU that is used for parallel computations. The result of the
processing is a list of texture mapped triangles representing the recon-
structed surfaces. In contrast to previous works, the entire processing
pipeline (foreground segmentation, 3D reconstruction, 3D mesh compu-
tation, 3D mesh smoothing and texture mapping) has been implemented
on the GPU. Experimental results demonstrate that an accurate, high
