The NormalToWorld method in the Transform struct is used to convert a normal vector from local space to world space. This is particularly useful when you need to transform normals for lighting calculations or physics interactions in a global context.
To use the NormalToWorld method, you need to have a Transform instance that represents the local transformation of an object. You can then call this method with a local normal vector to get the corresponding world space normal vector.
// Assume 'transform' is an instance of Transform Vector3 localNormal = new Vector3(0, 1, 0); // A normal pointing upwards in local space Vector3 worldNormal = transform.NormalToWorld(localNormal); // 'worldNormal' now contains the normal vector in world space
