9 MATERIALS REFERENCE» Displacement228Displacement maps are detailed maps, which are interpreted as height information.Using displacement maps you can create highly detailed structures fromrather simple geometry by just using a plain image. Each point on the geometryis displaced along the interpolated vertex normals using the height informationof the map, resulting in a realistic silhouette and producing correct shadows andreflections. Accuracy is only limited by the resolution of the texture image andmemory requirements are very low. To avoid cracks in the displaced surfacesthe vertex normals should be smooth and consistent. Using a higher tesselatedbases mesh can improve performance a lot.» Displacement Height: Defines the height of the displacement.» Use Accurate Silhouettes in OpenGL: Off by default, this feature allows to calculatethe displacement in OpenGL like in raytracing mode. Turning it on maydrastically reduce the performance.» Use Texture: Loads an image texture for the diffuse color channel. Uses theimage as pattern on the surfaces.
