    摘要： A method for Monte Carlo volume rendering in accordance with the present teachings includes: (a) tracing a plurality of light rays into a scene containing volumetric data, the light rays configured for simulating global illumination; (b) randomizing the scattering location and direction of the plurality of light rays through the volume, wherein a common sequence of random numbers is used in order for the scattering direction of each of the plurality of randomized scattered light rays to be substantially parallel; (c) computing at least one trilinearly interpolated and shaded sample along each of the plurality of randomized scattered light rays based on stored volumetric data, wherein at least a portion of the stored volumetric data used in at least a portion of the computing is configured for coherent access; and (d) rendering the volume with global illumination based on a plurality of iterations of the tracing, the randomizing, and the computing. Systems for Monte Carlo volume rendering are described.

    摘要： Disclosed are embodiments of a universal electroplating rack and method of using the rack. The universal electroplating rack comprises a main body adapted to accommodate and electrically connect to one or more customized inserts. Each customized insert is adapted to accommodate and electrically connect to a single workpiece. Additionally, both the main body and the customized insert(s) can comprise thief plates configured to improve plating uniformity across the plating surface area of the workpiece(s). Such a universal plating rack ensures a constant plating surface area regardless of workpiece size by varying the dimensions of the customized insert(s) so that universal processing parameters can be used for all workpieces. Consequently, for each new product developed, the universal electroplating racks of the invention will effectively reduce introduction costs, will avoid the need to qualify new electroplating process parameters (e.g., cycle time), and will effectively reduce lead time required.
