Displacement mapping shifts actual vertices of a model based on a texture (Displacement Map), making it appear truly deformed or bumpy.
Unlike normal mapping, displacement mapping actually alters the geometry of the object, which means it changes both its silhouette and depth.
Think of it as carving or sculpting an object based on a template (the displacement map). Each vertex on the surface shifts, so the model reflects the texture’s shape in a real, physical way.
