摘要： A method for automatically or semi-automatically constructing a digital 3D model of a scene from photographic data and photogrammetry data includes defining an initial rough model as a solution estimate. A reverse rendering step includes a second-order solution method that employs automatic differentiation techniques to accurately compute derivatives of an error function. In an embodiment of the method, at least one camera is placed within the scene being constructed, and photographic data from this camera is used in the solution process.

摘要： Systems and methods are provided for improving the latency for display of ink during user creation of ink content with an object, such as a stylus, mouse, finger (or other touch input), or other drawing device. A touchscreen display device is configured to perform a method for assigning pressure data to contact points, comprising receiving a first contact point from the touchscreen that is not associated with pressure information, wherein the first contact point is one of a plurality of contact points on a path made by an object across a surface of the touchscreen; determining a velocity of the object at the first contact point; determining a pressure that corresponds to the velocity; associating the pressure with the first contact point to generate an updated first contact point; and using the updated first contact point to render a digital ink.

摘要： Image-based lighting for use in rendering of digital objects is derived from image data collected from a real motion-picture set. The image data includes sets of correlated images at different exposure levels (302), each corresponding to a selected location. The image data is processed to define an extended dynamic range panoramic image (304) for each selected set location. The image data is color and intensity corrected based on a scaled reference object. At least key lights are modeled (306) for the set by processing a plurality of such panoramic images. Other lighting may be defined by interpolating from the panoramic images to mathematically define a location-specific set of fill lights. In the alternative, other set lighting may be modeled by projecting panoramic image data onto a dynamically sub-dividable light primitive derived from the set geometry. Any desired object may then rendered using the defined lights, and inserted into a corrected real image of the set at the desired location.

摘要： A computationally efficient method for rendering skin tissue (fig.5 element 160) to achieve lifelike results includes application of a blurring algorithm to a two-dimensional light map (fig.5 element 156). The algorithm is compact and is not derived from complex mathematical models of subsurface scattering in translucent materials fig.1 element 108), and yet achieves results similar to more complex models. The method includes receiving three-dimensional surface geometry relating to a digital object and other information for defining modeled light reflected from the surface, generating a two-dimensional matrix of light intensity values mapped (fig.1 element 105) to the surface geometry, blurring the matrix using a compact algorithm, and rendering the object using the blurred light intensity values (fig. 5 element 160).
