Adapting natural phenomena rendering for realtime applications has become a common practice in computer graphics. We propose a GPU-based multi-band methodfor optimized synthesis of “far from coast” ocean waves using an empirical Fourier domain model. Instead of performing two independent syntheses for low- and high-band frequencies of ocean waves, we perform only low-band synthesis and employ results to reproduce high frequency details ofocean surface by an optimized iterative up-sampling stage.Our experimental results show that this approach greatlyimproves the performance of original multi-band synthesiswhile maintaining image quality.
