There exists a powerful algorithm for shape reconstruction\u003c\/p\u003e\u003cp\u003efrom arbitrary viewpoints, called Space Carving. However, it is computationally expensive and\u003c\/p\u003e\u003cp\u003ehence can not be used with applications in the field of 3D video or CSCW as well as interactive 3D model\u003c\/p\u003e\u003cp\u003ecreation. Attempts have been made to achieve real-time framerates using PC cluster systems. While these\u003c\/p\u003e\u003cp\u003eprovide enough performance they are also expensive and less flexible. Approaches that use GPU hardware\u003c\/p\u003e\u003cp\u003eacceleration on single workstations achieve interactive framerates for novel-view synthesis, but do\u003c\/p\u003e\u003cp\u003enot provide an explicit volumetric representation of the whole scene. The proposed approach shows the\u003c\/p\u003e\u003cp\u003eefforts in developing a GPU hardware-accelerated framework for obtaining the volumetric photo hull of\u003c\/p\u003e\u003cp\u003ea dynamic 3D scene as seen from multiple calibrated cameras. High performance is achieved by employing\u003c\/p\u003e\u003cp\u003ea shape from silhouette technique in advance to obtain a tight initial volume for Space Carving. Also\u003c\/p\u003e\u003cp\u003eseveral speed-up techniques are presented to increase efficiency. Since the entire processing is done on a\u003c\/p\u003e\u003cp\u003esingle PC the framework can be applied to mobile setups, enabling a wide range of further applications.\u003c\/p\u003e\u003cp\u003eThe approach is explained using programmable vertex and fragment processors with current hardware and\u003c\/p\u003e\u003cp\u003ecompared to highly optimized CPU implementations. It is shown that the new approach can outperform\u003c\/p\u003e\u003cp\u003ethe latter by more than one magnitude. The downloadable introduction has been written specifically for this  offer.
