摘要： A computer graphics system generates a pixel value for a pixel in an image, the pixel value being representative of a point in a scene as recorded on an image plane of a simulated camera, the computer graphics system comprising a sample point generator and a function evaluator. The sample point generator is configured to generate a set of sample points, at least one sample point being generated using at least one dependent sample comprising at least one element of a low-discrepancy sequence offset by at least one element of another low-discrepancy sequence. The function evaluator is configured to generate at least one value representing an evaluation of a selection function at one of the sample points, the value generated by the function evaluator corresponding to the pixel value.

摘要： Computer graphics apparatus, methods, systems and program products (the term “programs” can include a product consisting of computer-readable program instructions encoded on a computer readable medium) are operable to generate pixel values for pixels in an image, and store or display a human-perceptible image based on the pixel values, using a selected ray-tracing methodology in which simulated rays are shot from the pixel into a scene, the simulated rays representing paths of simulated photons, the pixel value being representative of a point in a scene as recorded on an image plane of a simulated camera. The computer graphics system comprises a subdomain generator, a subdomain photon evaluator, an area value generator and a radiance value generator. An associated computer system generates, based on the pixel values, a display-controlling electrical output operable to control a display element and enable the display element to display an image.

摘要： The invention is directed to an arrangement for the generation of intensive short-wavelength radiation based on a gas discharge plasma. It is the object of the invention to find a novel possibility for generating intensive short-wavelength radiation, particularly EUV radiation, based on a gas discharge plasma which achieves a long life of the electrode system along with a high total efficiency of the radiation source without substantially increasing the dimensions of the discharge unit. This object is met, according to the invention, in that exclusively suitably shaped vacuum insulation areas which have the shape of an annular gap and which are formed depending on the product of gas pressure (p) and interelectrode distance (d) between the cathode and anode are provided for insulating the cathode and anode from one another in a cylindrically symmetric electrode arrangement for reliable suppression of electron arcing.
