A computer-based method and system for interactive volume rendering of a large volume data on a conventional personal computer using hardware-accelerated block filtration optimizing uses 3D-textured axis-aligned slices and block filtration. Fragment processing in a rendering pipeline is lessened by passing fragments to various processors selectively in blocks of voxels based on a filtering process operative on slices. The process involves generating a corresponding image texture and performing two-pass rendering, namely a virtual rendering pass and a main rendering pass. Block filtration is divided into static block filtration and dynamic block filtration. The static block filtration locates any view-independent unused signal being passed to a rasterization pipeline. The dynamic block filtration determines any view-dependent unused block generated due to occlusion. Block filtration processes utilize the vertex shader and pixel shader of a GPU in conventional personal computer graphics hardware. The method is for multi-thread, multi-GPU operation.

A plurality of vertex or fragment processors on a graphics processor perform computations. Each vertex or fragment processor is capable of executing a separate program to compute a specific result. A combiner manages the combination of the results from the respective processors, and produces a final transformed vertex or pixel value. The vertex or fragment processors and the combiner can be programmable to modify their operations. As such, the vertex or fragment processors can operate in a parallel or serial configuration, or both. The combiner manages and resolves the operations of the serial and/or parallel configurations. A synchronization barrier enables the combiner to perform data-dependency analysis to determine the timing and ordering of the respective processors' execution. A transformation module can include one or more programmable vertex processors that transforms three-dimensional geometric data into fragments. The fragment processors subsequently receive and compute a result for each fragment, which is combined using the combiner to produce the final pixel value.
