摘要： Described is a search technology in which spatially varying anisotropic reflectance is modeled using image data captured from a single view. Reflectance at each point is represented using a microfacet-based Bidirectional Reflectance Distribution Function (BRDF). Modeling processes the image data, which provides a partial normal distribution function (NDF) for each surface point. The NDF at each selected point is completed by texture synthesis using similar, overlapping partial NDFs from other points. Also described is a scanning device that illuminates a sample surface from a two-dimensional set of light directions using a linear array of LEDs moved over a flat sample.

摘要： A light gathering process may reduce the computational resources and storage required to render a scene with a participating homogeneous media. According to some implementations, Efficiency may be obtained by evaluating the final radiance along a viewing ray directly from the lighting rays passing near to it, and by rapidly identifying such lighting rays in the scene. To facilitate a search for nearby lighting rays, the lighting rays and viewing rays may be represented as a 6D point and a plane according to the corresponding Plucker coordinates and coefficients, respectively.

摘要： Removal of the effects of dust or other impurities on image data is described. In one example, a model of artifact formation from sensor dust is determined. From the model of artifact formation, contextual information in the image and a color consistency constraint may be applied on the dust to remove the dust artifacts. Artifacts may also be removed from multiple images from the same or different cameras or camera settings.

摘要： A real-time algorithm for rendering of an inhomogeneous scattering media such as smoke under dynamic low-frequency environment lighting is described. An input media animation is represented as a sequence of density fields, each of which is decomposed into a weighted sum of a set of radial basis functions (RBFs) and an optional residual field. Source radiances from single and optionally multiple scattering are directly computed at only the RBF centers and then approximated at other points in the volume using an RBF-based interpolation. Unique approximation techniques are introduced in the computational algorithms to simplify and speed up the computation of source radiance contributed by single and multiple scattering. Using the computed source radiances, a ray marching technique using slice-based integration of radiance along each viewing ray may be performed to render the final image.

摘要： An operating system shell has an underlying desktop object that is rendered according to different views. The operating system shell renders on a display screen a desktop graphical user interface with windows, tools, icons, etc. that are within a segment of the desktop object that can be observed (i.e., rendered) from one of the views. In illustrated implementations, the desktop object is of an extent that is greater than can be rendered from a single view. Allowing a user to select or access different views of the desktop object effectively provides an extended desktop that overcomes the fixed and limited display capabilities of conventional operating system shells.

摘要： Encoded HDR textures are described. In one aspect, a HDR image comprised is preprocessed such that HDR information is represented in a single color channel. The preprocessed image is quantized in view of two luminance ranges to retain HDR in the single color channel. Each block of quantized channel information is then encoded across two textures (encoded HDR textures). Specifically, when encoding a block of the quantized information, pixels in a first range of the two luminance ranges are put into a color channel associated with a first texture. Additionally, pixels in a second range of the two luminance ranges are stored into a color channel associated with a second texture.

摘要： A system is described for using a texture synthesis approach to produce digital images that simulate motion. The system operates by receiving a large-scale motion image that describes large-scale motion, as well as one or more exemplar images that describes small-scale motion. The system then applies a texture synthesis approach to duplicate the small-scale motion described in the exemplar image(s), as guided by the large-scale motion described in the large-scale motion image. This operation produces a synthesized motion image. The system then combines the synthesized motion image with the large-scale motion image to produce a combined motion image. The combined motion image presents the large-scale motion as modulated by the small-scale motion. The system can also take account for one or more application-specific constraints, such as incompressibility and boundary conditions.

摘要： Gradient domain editing of animated meshes is described. Exemplary systems edit deforming mesh sequences by applying Laplacian mesh editing techniques in the spacetime domain. A user selects relevant frames or handles to edit and the edits are propagated to the entire sequence. For example, if the mesh depicts an animated figure, then user-modifications to position of limbs, head, torso, etc., in one frame are propagated to the entire sequence. In advanced editing modes, a user can reposition footprints over new terrain and the system automatically conforms the walking figure to the new footprints. A user-sketched curve can automatically provide a new motion path. Movements of one animated figure can be transferred to a different figure. Caricature and cartoon special effects are available. The user can also select spacetime morphing to smoothly change the shape and motion of one animated figure into another over a short interval.

摘要： Described is a technology by which a GPU-based photon mapping mechanism/algorithm uses a kd-tree to render arbitrary dynamic scenes. For each frame, the mechanism emits and traces a set of photons into the scene. When a photon hits a surface, it can either be reflected, transmitted, or absorbed based on the surface material. Once photon tracing is done, a kd-tree is built for the stored photons. To estimate the radiance value at an arbitrary surface point, the k-nearest photons are located and filtered. The photon tracing and photon kd-tree construction, as well as the radiance estimation using k-nearest neighbor (KNN) searches are performed on graphics hardware, e.g., a GPU. In one example, only caustic photons are traced, whereby a photon is terminated and stored once it hits a diffuse surface.
