Abstract:

Most of current music visualizations are monotone. In this article, a aquarelle-style music visualization integrated perfectly with music was implemented. It adopts some key technologies, such as aquarelle effect based on alpha channel, tidy physical model, piecemeal joint, and composite anti-aliasing, etc. The example of music visualization by bloom, stalk, dimple and goldfish shows that this method can get good effect with low CPU occupancy and small memory request.

Key words: alpha channel, real-time rendering, music visualization, composite anti-aliasing
