If we instead represent this detail with a bump map, the surface geometry can become much simpler, and the detail is represented as a texture which modulates how light reflects off the surface. See in Glossary to represent the fine surface detail, and a lower resolution polygonal surface for the larger shape of the model. To avoid this, we should use a normal map A type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. Over a large model with lots of fine surface detail this would require a very high number of polygons to be drawn. On the right you can see the polygons required to make up the detail of a single screwhead. A sheet of aircraft metal with details modeled as real geometry.ĭepending on the situation it is not normally a good idea to have such tiny details modelled as “real” geometry.

One way to do this would be to model these details as geometry, as shown below. They are a special kind of texture that allow you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry.įor example, you might want to show a surface which has grooves and screws or rivets across the surface, like an aircraft hull.
