Controllable Procedural Generation of Landscapes - Unity Client

This is the Unity client repo for the ACM MM24 paper "Controllable Procedural Generation of Landscapes".

Environment

Unity 2022.3.14f1c1 (not tested with other versions, but a 2022.xx version should be OK)

Structure

The landscape models used are located in Assets/AssetStoreOriginals/APAC_Garden/Art, which are mostly from third-parties.

Assets/SceneGen is the main directory. The necessary files for conversion (which are the outputs of the main generation process, see the other repo) should be put into Assets/SceneGen/Inputs. The scripts for conversion are put in Assets/SceneGen/Scripts. Other directories are mainly used for the terrain textures.

By default, Assets/SceneGen/Image_Landscape, Assets/SceneGen/Scene_Landscape, and Assets/SceneGen/Mat_Landscape are used for storing the outputs.

Usage

1. Put all outputs of the main generation process into Assets/SceneGen/Inputs. Alternatively, you can try using the files in Assets/SceneGen/SampleInputs. Just ensure that height_map_xx.png, label_map_xx.png, and scene_xx.json are all put into the directory.
2. Open Unity and open any saved scene. By default, you can just open Assets/SceneGen/scene.unity.
3. From the menu bar, select "Tools"->"Landscape Generator", and then click "Generate".
4. Wait a few seconds (or several minutes if there are many scenes).
5. By default, the generated scenes are stored in Assets/SceneGen/Scene_Landscape. Some images of these scenes are rendered and saved in Assets/SceneGen/Image_Landscape (you can disable it by modifying Assets/SceneGen/Scripts/SceneRenderer.cs).

Others

The scripts for conversion are generally straightforward. You can modify them if necessary.

If you encounter some bugs, please create a issue.
