Introduction to hydrax and parameter description of hydraxdemo. hdx

1. What is hydrax?

Hydrax is an ogre add-on project that provides an easy-to-use library for rendering water.
It includes all the effects and is configurable, such as water depth, smooth conversion, blister effect, and corrosion effect, which can be selected in real time, and they do not rely on shaders such as RTT's texture quality, mesh size, grid complexity, Perlin Noise textures size, and hydrax components.
