This tutorial describes how CityEngine can be used to work for typical urban planning tasks. The actual creation of the building starts now.
You’ll use textured planes instead of the complex window asset. The left-to-right rectangular selection is usually used to select tiny objects such as single Street Graph Nodes when there are many objects occupying the same space. The following figures depict the extruded mass model first and the described decomposition into floors and tiles below. The following image shows the rule set applied to arbitrary mass models: The Roof rule prepares the UV coordinates to cover the entire roof face, sets the roof texture, and applies the texture coordinates to the geometry.
Selects a single object. Since writing custom distribution rules for building placement patterns can result in quite complex CGA code, we propose in this tutorial to simply use either point shapes or manually created footprint shapes of any form, as a faster way to control the footprint distribution.
Next, the floors are further broken down into elements called tiles floor subdivisions. The default folders that store your project data, such as assets, rules, and scenes, are already present, though empty.
This way, the windows and textures are set back 0. Selection type Result Single click. Of course, urban planning processes are typically reaching a much higher level of complexity than the simplified case described in this tutorial. The facades can now be modeled.

CityEngine is a procedural modeling application. In this section, you’ll add a simple level of detail LOD mechanism to your simple building. Otherwise LOD equals zerodo not load the window asset, but use a simple plane coming from the facade instead. Approximately streets were created, but you can’t see them all in the viewport until you frame the view. Select Objects of Same Type. Once you have a selection, the right mouse button context menu contains entries with which you can select additional elements.
This rule file is executed when the generation is triggered.
Tutorial 16: Urban planning
The appearance of the ground floor is often different from the other floors, especially for front facades. You’ll now create a low resolution version in a few steps. As you will see, CityEngine can be used in multiple contexts, disciplines, and planning phases for your projects.
Essential Skills project, which you should already have linked to your workspace. Later in this tutorial, you’ll need rule files and assets for the generation of the building models.
The modes are also listed in the Selection Tool submenu in the toolbar. Using the operation s x,y,zthe size of the scope can be set in the Esr rule. Selects all objects completely within the selection rectangle. The result of this section will look like the following image: The predefined styles for usage mixes, footprint shapes, and the ability to create grid-like arrays make this process substantially esgi simple.
The mass model is created with the extrude operation as follows:.
Tutorial 6: Basic shape grammar
The height is now defined as a random value between 15 and The Groundfloor rule refines the groundfloor shape cityengins a similar subdivision split, with the difference that an entrance is placed on the right.
You’ll analyze a finished rule file that contains all the steps to create a basic building. We increase the amenity of the entrance by adding a water basin and trees. Finally, we move our focus to the exterior space and add seri elements. Now you’ll copy all necessary files from the cityengime Tutorial 1 project into your new project.
The width and height of the scope are not affected since relative coordinates are used: You’ll use them now. They differ not only due to the existence of an entrance, but often also due to different sized floor heights, window appearance, color, and so on. Many people may find this quite intuitive and more flexible, especially for small to medium-sized contexts. The options are shown in the following table:.

Rather than listing all nine texture names as single assets, the function in step 2 returns one of the nine window textures in the asset folder. The building rules in this tutorial have a small set of attributes to actually design the building, especially the overall building volume. The Current Mouse Scheme drop-down menu lists the available schemes of other 3D apps.
Terrain and dynamic city layouts. While the Selection Cityengins is active, press Ctrl and Shift to either add or subtract from your selection. Same start rule on all visible layers. The z dimension is set to The simplest way this is done is by defining the value as a user set value in the rule. This tutorial was developed in collaboration with Matthias Buehler http:
