Displacement Map

A displacement map is a grayscale or vector texture that physically moves the vertices of a mesh along their normals to create real geometric detail. Bright values push the surface outward and dark values pull it inward, so the silhouette and shadows genuinely change. Unlike normal or bump maps, it alters actual geometry.

The renderer reads the height value at each point and offsets the corresponding geometry along its surface normal. Because it moves real vertices, the mesh needs enough polygons, or on-the-fly tessellation, to resolve the fine detail the map describes.

A displacement map moves real geometry, so it changes the model's silhouette and casts correct self-shadows. A normal map only alters how light reacts to a flat surface, leaving the silhouette unchanged. Displacement is heavier but more physically accurate.

Both use grayscale height data, but a bump map only fakes relief by perturbing shading, while a displacement map physically moves geometry. A bump map is cheap and leaves the outline flat; displacement is costlier and produces true depth.

Use displacement when the silhouette and self-shadowing must be physically correct, such as terrain, deep grooves, or close-up hero surfaces. Use normal maps for fine detail where performance matters and the outline can stay flat. A common workflow pairs coarse displacement with a fine normal map.

Displacement moves existing vertices, so there must be enough of them to represent the detail in the map. If the mesh is too low-resolution the detail is lost, which is why engines tessellate the surface at render time or artists subdivide the geometry first.

In Blender you connect a height texture to a Displacement node in the material and enable the Displacement setting, or add a Displace modifier for mesh-level control. Cycles supports true render-time displacement with adaptive subdivision for high detail.

Tessellation is the process of subdividing geometry into more polygons, while displacement is what moves those new vertices to form detail. They work together: tessellation supplies the density and the displacement map supplies the shape.

Yes. Meshy's PBR output pairs cleanly with displacement workflows, so you can layer height detail on top of AI-generated models for renders where the silhouette must be exact. This suits terrain, close-ups, and film-quality shots.
