CityEngine 2008

Building Editor
The Building Editor provides a workflow to build and customize buildings, facades, street items and other (generic) geometry. It enables the automated variation of buildings (including proportions and rythms) and appearance (for example the application of layered textures).
Scene Editor
The Scene Editor allows to browse and manage all elements (assets) that have been created in a CityEngine scene. The associated scripting window provides tools for both general and specific editing and manipulation of buildings and other city objects. You can also control the parameters of the individual building placement.
Variation Engine
CityEngine features a unique Variation Engine, which features quick changes of urban environments or single buildings to give the most flexibility for changing production needs.
Rythm and Proportion Tool
Building designs often comprises of repetitive elements. To give full control to the artist CityEngine offers a sophisticated rythm and proportion for authentic appearence of variated building designs.
Unique Split, Occlusion and Repeat operators
Dimensions are very important - even in virtual worlds. CityEngine's Split, Occlusion and Repeat operators govern a perfect fit of buildings and their elements into a given design context. For example, in case of a row house that is covering a facade of a neighboring house, both houses will not get any facade elements except wall on the occluded surface.
Directability
Artists can adjust many parameters of buildings like style, epoche, usage mix and building type. They can even give variation in every attribute of every building or a whole cityscape.
Intuitive Editing
Intuitive Editing of building location, street networks, materials and variations.
Street Network Editor
The Street Network Editor is used to design the layout of a city consisting of streets, districts, blocks and building lots. It grows urban street networks based on socio-statistical input, for example a simple population density or land-use map. Different street types follow density measures. Highways for example connect very dense population areas. Generated streets or building lots can be easily edited and modified.
Scalability
CityEngine was designed specifically to handle thousands of photorealistic buildings. For very large scenes, the geometry production and export processes can be run in batch mode.
Compatibility
CityEngine is compatible with industry standard geometry formats. Currently, we are supporting the following major formats: FBX, Collada and Wavefront OBJ/MTL.
Support for Software Rendering & Rendering Pipelines
To optimize the use of CityEngine models in the production pipeline, we support direct (and instanced) export into the scene description languages of Pixar's RenderMan (tm) and Mental Images' Mental Ray (tm).
Built In Asset Manager
The CityEngine includes an Asset Manager whichs allows for the preview and organisation of all the (architectural) geometry objects used in a scene.
