Align objects to the water surface using normals

When accessing height, you can query the normal of the water surface at a given point as an additional output.

1. Set the following variable in the search parameter struct sent to the system:

    searchParameters.outputNormal = true;
   

2. Use the result to align an object along the surface of the water, for example:

    gameObject.transform.LookAt(searchResult.projectedPositionWS + searchResult.normalWS, Vector3.up);
   

3. When using the Burst version of the API, allocate the array to store normals.

   The following script contains only the relevant lines to add to the script to float an array of objects to support querying normals.

    public class FitToWaterSurface_Burst : MonoBehaviour
    {
        NativeArray<float3> normalWSBuffer;
   
        void Start()
        {
            normalWSBuffer = new NativeArray<float3>(resolution * resolution, Allocator.Persistent);
        }
   
        void Update()
        {
            searchJob.outputNormal = true;
            searchJob.normalWSBuffer = normalWSBuffer;
        }
   
        private void OnDestroy()
        {
            normalWSBuffer.Dispose();
        }
    }
