    摘要: A method and device for efficiently simulating lens flares produced by an optical system is provided. The method comprises the steps of—Simulating paths of rays from a light source through the optical system, the rays representing light; and Estimating, for points in a sensor plane, an irradiance, based on intersections of the simulated paths with the sensor plane.

    摘要: A variety of methods, devices and storage mediums are implemented for creating digital representations of figures. According to one such computer implemented method, a volumetric representation of a figure is correlated with an image of the figure. Reference points are found that are common to each of two temporally distinct images of the figure, the reference points representing movement of the figure between the two images. A volumetric deformation is applied to the digital representation of the figure as a function of the reference points and the correlation of the volumetric representation of the figure. A fine deformation is applied as a function of the coarse/volumetric deformation. Responsive to the applied deformations, an updated digital representation of the figure is generated.

    摘要: A method and a device for determining shadows in a computer-generated image are provided, wherein the determination whether a pixel x is in shadow is based on a shadow test function ƒ(d(x), z(P)), d(x) representing the depth of the pixel x with respect to the light source and z(p) being a shadow map z for the computer-generated image. According to the invention, the shadow test function ƒ satisfies f  ( d  ( x ) , z  ( p ) ) = ∑ i = 1 N  a i  ( d  ( x ) )  B i  ( z  ( p ) ) wherein ai are weighting coefficients depending on d, Bi are basis functions in terms of z and N is a natural number.

    摘要: Moiré is an appealing visual effect observable when two or more repetitive patterns are superposed. We introduce a method for designing and fabricating level-line moirés on curved surfaces. These moiré shapes are obtained by superposing a partly absorbing or partly light deviating curved base layer and a curved revealing layer formed by a grating of transparent lines or cylindrical lenses. The distances between base layer and revealing layer are adapted to the locally varying distances between successive transparent lines or cylindrical lenses of the curved revealing layer grating. We demonstrate the quality of our method by rendered simulations and by fabrication. The resulting level-line moiré display devices can be manufactured using different fabrication techniques, from multi-material 3D printing to molding.
