 The goal of this project is to develop a tool that integrates vegetation (trees) into 3D urban models in order to improve the efficiency of thermal simulations.

 == Installation and Usage
 
 === Install Required Packages
 
-This project uses link:https://www.cgal.org[CGAL], link:https://curl.se/[curl] and link:https://github.com/nlohmann/json[nlohmann/json libraries]. Go check them out if you don't have them locally installed.

 === Set up an environment 
 We provide here two example of environment, Mamba and venv
@@ -52,42 +46,44 @@ source .venv/bin/activate
 With the environment set up, install the required packages:
 
 ```bash
-pip install -r requirements.txt
+mamba install -c conda-forge cgal-cpp  fmt spdlog mpfr boost-cpp curl -y
 ```
 
+=== Alternatively you can use a Docker container:
+```bash
+docker build -t 2024m1vegetation:latest
+docker run -it 2024m1vegetation:latest
+```
+
+Note: on VsCode you can use the Remote - Containers extension to reopen the project in a container.
+
 === Build the Project
 
 Configure and build the project using CMake:
 ```bash
-# Configure CMake
-cmake --preset default
+cd build
+# Clean the build directory
+rm -rf *
 
 # Build the project
-cmake --build --preset default
+cmake ..
 
-# Test the build
-ctest --preset default
-```
+# Compile the project
+make
 
-=== Usage (currently a basic alpha wrapper)
-
-To use the alpha wrapper, run the following command:
-
-```bash
-./build/default/bin/wrap <input_file> <alpha> <offset>
+# Run the tests
+make test
 ```
 
-The output mesh will be saved in the `/output`` folder.
-
-=== Example
-
-Here's an example of how to use the alpha wrapper:
+=== Usage 
 
 ```bash
-./build/default/bin/wrap data/trees/oranger.off 10
+./build/run
 ```
 
-=== Notes
+The `config.json` file contains the gps coordinates of the 2 corners of the area to pull data from OpenSTreetMap.
+
+The output mesh will be saved in the `/temp` directory.
 
 You can visualize the output mesh with **Meshlab** or any other mesh viewer. (Note: Meshlab does not work well with Wayland.)
