Numerical simulation of a structure of the fluctuating field appearing at a kinetic stage of the phase transition is performed for the systems with scalar and two-component (complex) order parameters. It is found that the ordering process is accompanied by a large-scale filamentary structure of the fluctuating field. The dense local groups and chains of the nuclei are created in the system. A complicated topology of the ordering is found in the system with complex order parameter. This system creates specific ``toroidal'' vortices. Kinetic scenarios in 3D-space are compared with the 2D- and 1D projections of the analogous structures previously found.
