deprecated Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. The concept of positioning textures on surfaces complies with the standard X3D. Because there has been no appropriate texturing concept in GML3, CityGML adds the class TexturedSurface to the geometry model of GML 3. A texture is specified as a raster image referenced by an URI, and can be an arbitrary resource, even in the internet. Textures are positioned by employing the concept of texture coordinates, i.e. each texture coordinate matches with exactly one 3D coordinate of the TexturedSurface. The use of texture coordinates allows an exact positioning and trimming of the texture on the surface geometry. Each surface may be assigned one or more appearances, each refering to one side of the surface. deprecated Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. A property that has an _Appearance as its value domain, which can either be a Material (Color,...) or a Texture. The _Appearance Element can either be encapsulated in an element of this type or an XLink reference to a remote _Appearance element (where remote geometry elements are located in another document or elsewhere in the same document). Either the reference or the contained element must be given, but neither both nor none. The side of the surface the _Appearance refers to is given by the orientation attribute, which refers to the corresponding sign attribute of the orientable surface: + means the side with positive orientation, and - the side with negative orientation. deprecated Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. This abstract type is the parent type of MaterialType and SimpleTextureType. It is derived from gml:AbstractGMLType, thus it inherits the attribute gml:id and may be referenced by an appearanceProperty, although it is defined elsewhere in another appearanceProperty. deprecated Deprecated since CityGML version 0.4.0.

Use the concepts of the CityGML Appearance module instead. Textures can be qualified by the attribute textureType. The textureType differentiates between textures, which are specific for a certain object and are only used for that object (specific), and prototypic textures being typical for that kind of object and are used many times for all objects of that kind (typical). A typical texture may be replaced by a specific, if available. Textures may also be classified as unknown. deprecated Deprecated since CityGML version 0.4.0.
