Using different deformation maps that have elements corresponding to respective pixels deriving from an original image and have low-spatial frequency components, the elements indicating a moving direction and a moving amount of the corresponding pixels, the pixels deriving from the original image are moved in a moving direction by a moving amount, the moving direction and the moving amount being specified by the elements corresponding to the respective pixels, and modulated images are obtained. The modulated images are separated into brightness components and color components to obtain brightness component images and color component images, brightness of brightness component images and/or color of color component images is modulated to obtain brightness-modulated image and/or color-modulated image, and a video is obtained, the video being configured by arranging integrated images obtained by integrating the obtained brightness-modulated images and/or color-modulated images.

A method for generating visual representations of interactions between two different materials is provided. The method can be performed using a computing device operated by a computer user or artist. The method includes modeling a primary material as a plurality of first particles and modeling a layer portion of a secondary material as a fluid volume.

At least one boundary condition might be assigned to a boundary positioned between the layer portion and the outer portion, the at least one boundary condition includes at least one pressure value. Values of motion parameters might be determined by applying the at least one boundary condition at the boundary and generating one or more visual representations of the primary material interacting with the secondary material based on the values of the motion parameters.

A computer-implemented method for inverse simulation of a plurality of fibers. The method comprises: providing a computational model for describing mechanical behavior of fibers; obtaining target geometry information describing a target configuration or dynamical behavior of the plurality of fibers; and inverse simulating the behavior of the plurality of fibers, using the computational model and the target geometry information, to calculate a target set of fiber mechanical parameters for the plurality of fibers. Fibers with the calculated target set of fiber mechanical parameters exhibit the target configuration or dynamical behavior. In some embodiments, the inverse simulation comprises using analysis-by-synthesis to help derive the target set of fiber mechanical parameters. In some embodiments, the inverse simulation uses a neural network to infer information about fiber mechanical parameters from the target geometry information. The invention also provides a method of training the neural network.
