A method includes generating, based on user images, a user 3-D model. The method proceeds with obtaining, via a user interface, a request to graphically represent an accessory on to a user graphical representation. This user graphical representation is generated using the user 3-D model. In response to this request, an accessory 3-D model is obtained. Further, the method includes positioning, via the user interface and based on parameters of the user 3-D model and of the accessory 3-D model, an accessory graphical representation on to the user graphical representation. The method further includes updating, in response to detecting user movement, the user 3-D model and the accessory 3-D model and presenting, via the user interface and based on these updated 3-D models, the accessory graphical representation and the user graphical representation in accordance with the user movement.

A visual perception of an arbitrary transparent material is imparted to an arbitrary image. In accordance with each element of each deformation map included in a sequence of deformation maps that correspond to a time series, each element of a target image is moved to obtain each deformed image of the time series. Each element of each of the deformation maps indicates a movement direction and a movement amount of each pixel of the target image corresponding to the element. Each deformation map included in a sequence of deformation maps corresponding to a first time interval in the time series corresponds to each of two-dimensional arrays obtained by moving, in a first direction, elements of two-dimensional arrays corresponding to immediately-previous deformation maps, and each deformation map included in a sequence of deformation maps corresponding to a second time interval in the time series corresponds to each of two-dimensional arrays obtained by moving, in a second direction, elements of two-dimensional arrays corresponding to immediately-previous deformation maps. Here, the first direction and the second direction differ from one another.
