What is displacement modifier?

A displacement modifier is a tool used in 3D modeling and computer graphics to alter the surface of a 3D object by displacing its vertices based on a texture or height map. This technique allows for the creation of complex surface details, such as bumps and grooves, without adding extra geometry. Displacement modifiers are commonly used in rendering to achieve more realistic textures and details in models. They can be applied in various software, including Blender and Maya, enhancing the overall visual quality of the rendered scene.
