Displacement in 3D modeling texturing uses a texture map to modify a model’s surface geometry, creating real physical depth or height variations.
Unlike bump or normal maps (which only simulate depth visually), displacement actually changes the mesh, adding true details like wrinkles, stone grains, or terrain.
It’s vital for realistic work in games, VFX, or product design where genuine geometric detail matters.
To try it, use a simple grayscale texture (white = high, black = low) on a basic mesh (like a cube) in Blender—small adjustments will show how displacement affects the surface.
