<p>Wave attractors are peculiar phenomena that occur in stratified/rotating fluid due to internal/inertial waves self-focusing. The huge energy accumulation taking place in such types of slow leads to an intense instability production, and secondary waves make the observation of the attractor more difficult. The existing at the moment methods for wave attractor visualization uses the filtration by temporal behaviour which requires long history. In this article, a new method considering spatial structure is proposed. It allows to process only a few snapshots to visualize the wave attractor in a non-linear regime.</p>
