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 rendering or physics calculations, ensuring they are correctly oriented in the global coordinate system.
To use the NormalToWorld method, you need to have a Transform instance and a local normal vector that you want to convert to world space. The method takes a reference to a Vector3 representing the local normal and returns a Vector3 that represents the normal in world space.
Ensure that the Transform instance is properly initialized with the correct position, rotation, and scale before calling this method to get accurate results.
// Example usage of Transform.NormalToWorld // Assume we have a Transform instance Transform transform = new Transform(); // Define a local normal vector Vector3 localNormal = new Vector3(0, 1, 0); // Example normal pointing up in local space // Convert the local normal to world space Vector3 worldNormal = transform.NormalToWorld(ref localNormal); // worldNormal now contains the normal vector in world space
