7.1 Truelight Materials» DisplacementDisplacement maps are detailed maps, which are interpreted as height information.Using displacement maps you can create highly detailed structuresfrom rather simple geometry by just using a plain image. Each point on thegeometry is displaced along the interpolated vertex normals using the heightinformation of the map, resulting in a realistic silhouette and producing correctshadows and reflections. Accuracy is only limited by the resolution of thetexture image and memory requirements are very low. To avoid cracks in thedisplaced surfaces the vertex normals should be smooth and consistent. Usinga higher tesselated bases 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.225
