Aquatica engine can be used to simplify the implementation of water surfaces in application with DirectX9 graphics. Key features of the engine:Water surface approximation using heightmaps, Heightmaps can be generated in real-time using FFT or Perlin noise, Generation of normalmaps, Generation of geometry: simple grid, geomipmap grid, radial grid, Water rendering options include: reflections, refractions, CPU/GPU displacement...
