摘要： Adaptive sampling alleviates aliasing by partitioning the field of view of an image sample point into depth regions. Portions of the scene are sampled within a depth region using sample rays. If a sample ray is not completely occluded in the depth region, corresponding sample rays are evaluated in adjacent depth regions. Sample rays can be recursively evaluated in further depth regions until all the subsamples intersect opaque objects or a depth limit or transparency threshold is reached. The value of an image sample point is the weighted combination of sample rays. The number of sample rays in each depth region may increase monotonically with distance along a line of sight from an image sample point for effects such as reflection, refraction, and illumination. The number of sample rays in each depth region may increase monotonically with distance from a focal plane for effects such as depth of field.
摘要翻译：自适应采样通过将图像采样点的视野划分为深度区域来缓解混叠。场景的部分使用采样光线在深度区域内采样。如果样品射线未在深度区域中完全闭塞，则在相邻的深度区域中评估相应的样品射线。可以在更深的深度区域递归地评估采样光线，直到所有子样本与不透明物体相交或达到深度限制或透明度阈值。图像采样点的值是采样光线的加权组合。每个深度区域中的采样光线的数量可以从图像采样点沿着视线的距离单调增加，以用于诸如反射，折射和照明的效果。每个深度区域中的采样光线的数量可以随着距离焦平面的距离而单调增加，以用于诸如景深的影响。

摘要： Methods for processing print jobs in rendering devices include representing multiple to-be-printed objects with fewer such objects before processing of the objects occurs. In this manner, processing and memory requirements are optimized. Examples include utilizing a single raster operation function of one object for an entirety of objects; using fewer raster operation functions than originally required for the entirety of objects; creating a no processing (NOP) situation; and effectively creating a mask. Other aspects include modifying raster operation functions of one or more objects to have fewer variables than originally specified by the print job. Printers having stored or accessible computer executable instructions for performing the steps are also disclosed as are host devices that may direct or control the printer to perform the same.

摘要： The present invention provides a method and apparatus for accurately matching colors. The color matching system includes a host computer and a color input device in communication with the host computer. Preferably the color input device is capable of obtaining spectral data, such as that obtained using a spectrophotometer. The host computer includes a color library, a color management system, a monitor, and a user interface. In one aspect of the invention, the user selects a target color, a color library to use for matching, a color distance tolerance, and a light source under which the colors are to be matched. The target color is compared to the colors in the library and the color or colors in the library that are within the specified color tolerance are reported. In a second aspect of the invention, the user selects a color and two illuminants. The color under each of the two illuminants is compared and the color distance between the two is reported. In a third aspect of the invention, a selected color is transformed to the color space of a designated printer and then back-transformed to the color space of the monitor and displayed. The displayed color represents a simulation of the selected color as it would appear if printed.

摘要： A computer database contains visual and other information of an object scene from which a television monitor or film display is created by electronically sampling points of the object scene information in the computer memory. Undesirable effects of aliasing are significantly reduced and substantially eliminated by pseudo-randomly distributing, in a particular manner, the occurrence of the point samples in space and time. Realistic depth of field is obtained in the images, corresponding to what is observed through a camera lens, by altering the sample point locations to simulate passing them through an optical aperture in a pseudo-random distribution thereacross. Further, effects of illumination, shadows, object reflection and object refraction are made more realistic by causing each sample point to pseudo-randomly select one of a predetermined number of possible ray directions.

摘要： An ordered object list is compared with an ordered ray list and if the coordinate value of an entry in the ray list is less than the coordinate value of an entry in the object list, then the ray is added to an active ray list, and a trace of that ray is made against all objects in an active object list. If the coordinate value of the entry in the ray list is greater than the coordinate value of the entry in the object list, then the coordinate value corresponding to the entry in the object list is added to an active object list, and a trace of all rays in the active ray list is made against that coordinate value. Rays and objects are removed from the active lists based on determinations as to whether a trace hit occurred and/or which object point is encountered.

摘要： A method for rendering an image including objects defined by surfaces. A rendering application selects an object in a first image and determines a surface of the object. An initial set of illumination values is calculated and is separated into low and high spatial frequency components associated with the surface of the object. The rendering application independently adjusts the illumination values of the low and high spatial frequency components based lighting information in the first image, and generates a modified set of illumination values by combining the adjusted low and high spatial frequency components. The surface of the object is then rendered using the modified set of illumination values. Advantageously, embodiments of the invention provide techniques for rendering an object without introducing halo effects around the object. Additionally, embodiments of the invention provide for rendering a sequence of frames without introducing fluctuations in the low frequency components from across frame.

摘要： Surfaces without a global surface coordinate system are divided into surface regions having local surface coordinate systems to enable the caching of surface attribute values. Surface attribute functions are evaluated to determine surface attribute values for the surface regions. A surface attribute value for a surface region may include contributions from two or more adjacent surfaces. A multiresolution cache stores surface attribute values at different resolution levels for surface regions of one or more surfaces, which may be discontiguous. Surface attribute values for a surface are retrieved from the multiresolution cache by dividing the surface into surface regions at a desired resolution level and selecting a corresponding resolution level of the multiresolution cache. One or more cached surface attribute values are retrieved for each surface region. Surface attribute values can be artistically or procedurally generated and can specify surface attributes including optical, illumination, animation, simulation, modeling, or rendering attributes.
