Optimized anisotropic texture sampling

ActiveUS7339594B1Quality and performance be balanceIncrease and decrease numberTexturing/coloringCathode-ray tube indicatorsState variableAnisotropic filtering
Systems and methods for determining the number of texture samples used to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance or image quality. The number of texture samples may be increased or decreased based on texture state variables that may be specific to each texture map. Furthermore, the texture samples may be positioned along an axis of anisotropy to approximate an elliptical footprint, ensuring that the texture samples span the entire axis of anisotropy. A graphics driver may load the texture state variables and configure a system to modify the number of texture samples and / or position the texture samples used to produce the anisotropically filtered texture mapped pixel.

Progressive addition power lens

InactiveUS20050012895A1Effective areaReduces peak of astigmatismOptical partsSuccessive over-relaxationRelaxation equation
A system and method for designing a progressive lens are provided. Mean power is specified at points distributed over the entire surface of the lens and lens height is specified around the edge of the lens. Lens height is determined at the points consistent with the specified mean power and the lens edge height in part by solving a partial differential equation of the elliptic type subject to the lens edge height as a boundary condition. A successive over-relaxation technique may be employed to converge on the solution to the partial differential equation, and an over-relaxation factor may be determined to most efficiently relax the equation.

Tungsten carbide-intermetallic compound hard alloy of twin structure and preparation method thereof

The invention provides a tungsten carbide-intermetallic compound hard alloy of a twin structure. The alloy comprises a hard phase WC and an adhesive phase Ni3Al or FeAl or Fe3Al, wherein the adhesive phase is 10 to 40 volume percent. A manufacturing method for the alloy sequentially comprises the following steps of: mixing Ni powder or Fe powder, Al powder and fine WC powder uniformly according to the component proportion of the Ni3Al or the FeAl or the Fe3Al; spreading the mixed powder in a graphite container, heating the mixed powder to the temperature of between 900 and 1,200 DEG C under a non-oxidizing atmosphere, preserving the heat for over 1 hour, naturally cooling the heated powder, and coating the adhesive phase to the surface of the fine WC; grinding, crushing and screening the mixture of the fine WC and the adhesive phase; performing deoxidation pretreatment at the temperature of 400+/-50 DEG C under the hydrogen atmosphere; performing pre-wet milling on 52.31 to 75.97 weight percent or 55.79 to 76.97 weight percent or 53.66 to 76.37 weight percent of crude granular WC powder and the balance of mixed powder to obtain a wet milled mixture; performing spray drying and pressure molding; and performing low-pressure liquid phase sintering at the temperature of between 1,250 and 1,550 DEG C, and thus obtaining the tungsten carbide-intermetallic compound hard alloy of the twin structure. The crude crystal WC and the fine crystal WC are matched uniformly, so the alloy has high densification, high strength, good abrasion resistance and excellent high-temperature oxidation resistance and corrosion resistance; and the preparation method is simple and low in cost.
