摘要： A method and system for implementing capturing and rendering geometric details for mesostructure surfaces is described herein. A mesostructure distance function is defined as a function of a given reference point and a given viewing direction. A distance from a reference point to a mesostructure surface point along a viewing direction is measured using the mesostructure distance function. This distance is used to determine the visibility of mesostructure surface for rendering silhouettes. The lighting visibility of the mesostructure surface point may also be determined and used for determining whether the mesostructure surface point is in shadow. This determination may then be used for rendering shadow silhouettes.

摘要： The described systems and methods are directed at interactively rendering graphics using precomputed radiance transfer (PRT). A reflectance matrix that represents the reflectance of a particular object to be rendered is determined. Source lighting associated with the object is represented using basis functions. The reflectance matrix is factored into view and light components. A raw transfer matrix is determined based, in part, from the factored reflectance matrix and the source lighting. The raw transfer matrix is partitioned to obtain transfer matrices, which are used to render the object. The described systems and methods are capable of rendering glossy objects with well-defined shadows.

摘要： Computer graphics image rendering techniques render images modeling transfer at two scales. A macro-scale is coarsely sampled over an object's surface, providing global effects like shadows and interreflections cast from an arm onto a body. A meso-scale is finely sampled over a small patch to provide local texture. Low-order spherical harmonics represent low-frequency lighting dependence for both scales. To render, a coefficient vector representing distant source lighting is first transformed at the macro-scale by a matrix at each vertex of a coarse mesh, resulting in vectors representing a spatially-varying hemisphere of lighting incident to the meso-scale. A radiance transfer texture specifies the meso-scale response to each lighting basis component, and a function of a spatial index and a view direction. A dot product of the macro-scale result vector with the vector looked up from the radiance transfer texture performs the correct shading integral. An id map places radiance transfer texture samples from a small patch over the object's surface, so that only two scalars are specified at high spatial resolution.

摘要： An image generator takes graphical objects and an occlusion relationship for the objects and resolves non-binary occlusion cycles with image compositing operations to produce an output image of the objects. The image generator takes an occlusion relationship for objects in a scene and a set of antialiased image layers with transparency of the objects and produces an antialiased image of the objects with hidden surfaces eliminated. One implementation operates on subsets of the objects in a scene that form non-binary cycles. This implementation uses a chain of atop operators to combine occluding objects with a selected object from a subset, and then combines this result with other objects in the cycle using over image operations. Another implementation computes a chain of out image operations for each object to combine the image layers of the occluding objects with the image layer of the object. The results of each chain of out image operations are summed to produce an output image.

摘要： A layered graphics rendering pipeline for real time 3D animation independently renders terms in a shading model to separate image layers. The layered pipeline factors the shading model into separate image layers and renders geometry to these layers independently. Each layer can have an independent update rate and a spatial resolution different than the resolution of the output images. A compositor that supports one or more image operators composites the factored layers into an output image to generate frames of animation. To reduce rendering overhead, factored terms can be rendered once and then re-used in later frames by warping the initial rendering.

摘要： A dense guide image or signal is used to inform the reconstruction of a target image from a sparse set of target points. The guide image and the set of target points are assumed to be derived from a same real world subject or scene. Potential discontinuities (e.g., tears, edges, gaps, etc.) are first detected in the guide image. The potential discontinuities may be borders of Voronoi regions, perhaps computed using a distance in data space (e.g., color space). The discontinuities and sparse set of points are used to reconstruct the target image. Specifically, pixels of the target image may be interpolated smoothly between neighboring target points, but where neighboring target points are separated by a discontinuity, the interpolation may jump abruptly (e.g., by adjusting or influencing relaxation) at the discontinuity. The target points may be used to select only a subset of the discontinuities to be used during reconstruction.
摘要翻译：使用密集的引导图像或信号来通知来自稀疏目标点集合的目标图像的重建。引导图像和目标点集合被假定为从相同的现实主题或场景导出。在引导图像中首先检测到潜在的不连续性（例如，泪液，边缘，间隙等）。潜在的不连续性可以是Voronoi区域的边界，可以使用数据空间中的距离（例如，颜色空间）来计算。不连续点和稀疏集合点用于重建目标图像。具体地说，目标图像的像素可以在相邻目标点之间平滑地内插，但是当相邻目标点被不连续分开时，插值可能突然地跳跃（例如，通过调节或影响松弛）而跳跃。目标点可以用于仅在重建期间仅选择要使用的不连续的子集。
