Abstract (en)

[origin: WO9847105A1] An apparatus including a three-dimensional buffer (438); a pixel bus (442); a plurality of rendering pipelines (440); and a control unit(454). Each rendering pipeline includes a first slice unit (544); a compositing unit (464); a two-dimensional slice compositing buffer (474); and a first interpolation unit (472 or 546). Sample point values are combined with pixels of the compositing buffer in the compositing unit along a plurality of interslice ray segments (410) which extend only between a current slice contained in the slice unit and a slice contained in the two-dimensional slice compositing buffer. Gradients are also computed at voxel positions to improve accuracy.
