I would like to ask a question, I am looking at the knowledge about water surface movement recently, I am using some knowledge like Genstener wave, I would like to ask what equation is used to fit the default water surface material of Babylonjs

You can find the code here:

sebavan/Babylon.js/blob/master/packages/dev/materials/src/water/water.vertex.fx#L137


      
          #include<vertexColorMixing>

          

          	// Point size

          #if defined(POINTSIZE) && !defined(WEBGPU)

          	gl_PointSize = pointSize;

          #endif

          

          	float finalWaveCount = 1.0 / (waveCount * 0.5);

          

          	vec3 p = position;

          	float newY = (sin(((p.x / finalWaveCount) + time * waveSpeed)) * waveHeight * windDirection.x * 5.0)

          			   + (cos(((p.z / finalWaveCount) +  time * waveSpeed)) * waveHeight * windDirection.y * 5.0);

          	p.y += abs(newY);

          	

          	gl_Position = viewProjection * finalWorld * vec4(p, 1.0);

          

          #ifdef REFLECTION

          	worldPos = viewProjection * finalWorld * vec4(p, 1.0);

          	

          	// Water

          	vPosition = position;
