Legolize

Transform Terrain into Bricks

legolize is a Blender add-on that converts QGIS-exported terrain data into a stylized brick landscape.

Installation and Usage

1. In QGIS:

   • Ensure you have a DEM layer and a color layer.
   • Create a new print layout with a square map.
   • Select the DEM layer and ensure it's visible in the print layout.
   • Save the image as "displacement.png" in your installation directory.
   • Make the color layer visible and ensure it's correctly positioned.
   • Save this image as "color.png" in the same installation directory.

2. Download the legolize.py file to your installation directory.

3. In Blender:

   • Open Blender, select and delete the default cube.
   • Go to the Scripting workspace.
   • Load and run the legolize.py file.
   • Switch back to the Modeling or Layout workspace.
   • Open the sidebar (N key) to see the Legolize panel.
   • Adjust settings as desired.
   • Click "Legolize!" to generate the brick landscape.
   • Render your scene.

To update with new terrain:

• Return to QGIS and repeat steps to export new "displacement.png" and "color.png" images.
• In Blender, simply click "Legolize!" again to update with the new terrain data.
