The basic methodologies used in animation are presented and their most significant problems connected with combining real and virtual worlds are recognised.Measured objects are classified into groups based on their mechanical properties and behaviour. The optical methods of shape and movement parameters determination adequate for fast virtual object generation are presented. Combination of various fringe projection techniques with photogrammetry is proposed to calculate the temporal shape and position of the object points. The spatio-temporal analysis of a projected fringe pattern delivers information about object shape and its out-of-plane deformation. The shape of measured object is calculated based on algorithm spatial carrier phase shifting technique. The analysis of marker dislocations during the measurement provides information about object shifts within the measurement volume. Combined information about object shape and its dislocation during the measurement enable to generate a virtual model that can be used to generate e.g.: realistic animation.The short comparison between proposed method and currently available systems is given and exemplary results of measurements are presented. The further directions of development of proposed techniques are presented.
