I’m studying the RT Fluid Example in Example Content, and I found that the material called HeightSim is a very important part.
After studying the example, I think the idea of generating water waves is to find the edge of the water wave to expand the water wave, and then subtract the last water wave (it should be able to form different heights and “move” wave), so as to form a larger and larger circle.
So I try to describe every node in HeightSim, but I can’t understand why multiply 0.5 for PreviousHeight1 to make the water wave normal (greater than 0.5 will be crazy, less than 0.5 will become strange)
Why multiply this by 0.5?
