GardenDesigner: Encoding Aesthetic Principles into Jiangnan Garden Construction via a Chain of Agents
The paper presents GardenDesigner, a novel framework that leverages a chain of specialized agents and encoded aesthetic principles to automate the generation of diverse and aesthetically pleasing Jiangnan gardens, enabling non-expert users to create complex digital environments via simple text inputs in under a minute.

Imagine you want to build a traditional Jiangnan Garden. These are the famous, intricate Chinese gardens known for their winding paths, tiny rock mountains, reflective ponds, and hidden pavilions.
Traditionally, building one (even digitally) is like trying to compose a symphony without knowing music theory. You need a master architect, a historian, and a botanist working together for weeks. They have to dig through old books, hand-model every rock, and carefully place every tree to ensure the garden feels "right" according to ancient, unwritten rules of beauty.
GardenDesigner is like a super-smart, magical gardening assistant that does all this heavy lifting for you in under a minute. You just type a sentence like, "I want a peaceful garden with a small pond, a red bridge, and a pavilion for watching the moon," and the system builds the whole thing for you.
Here is how it works, broken down into simple parts:
1. The "Chain of Agents": A Team of Specialized Robots
Instead of one giant brain trying to do everything at once, GardenDesigner uses a team of four specialized "robots" (called agents) that pass the work down the line, like an assembly line in a factory:
- The Landscaper (Terrain Agent): First, it looks at your text and draws the ground. It knows that Jiangnan gardens are all about water. So, it doesn't just make flat ground; it creates a landscape where water is the "soul" of the garden, surrounded by little hills and flat areas, just like nature intended.
- The Pathmaker (Road Agent): Next, it lays down the walking paths. In a regular park, paths might be straight and efficient. But in a Jiangnan garden, the path is an adventure! This agent makes sure the paths are winding and winding, forcing you to turn corners and discover new views, rather than seeing the whole garden at once.
- The Curator (Asset Selection Agent): Now it needs to pick the furniture. It has a massive library of 3D rocks, plants, and buildings. But it doesn't just grab random items. It acts like a museum curator who knows the cultural rules. It knows, for example, that a specific type of pine tree belongs near a rock, or that a pavilion should face the water. It picks the perfect items based on your description.
- The Interior Designer (Layout Agent): Finally, it arranges the furniture. It uses a set of invisible "rules of beauty" (like "don't put two big rocks right next to each other" or "keep the path open for a view"). It nudges everything into place until the whole scene feels balanced and harmonious.
2. The Secret Sauce: "GardenVerse"
You can't build a great garden without good materials. The researchers created a special database called GardenVerse.
- Think of this as a gourmet pantry instead of a generic grocery store.
- Instead of just having "a rock" or "a tree," they have 132 specific, high-quality 3D models of rocks, plants, and buildings that actually look like they belong in a Jiangnan garden.
- Crucially, they asked real human experts to write "notes" on these items. For example, a note might say, "This moon gate looks best when placed against a white wall with a circular window." The AI reads these notes to make smart decisions.
3. The "Aesthetic Principles": The Rules of the Game
The magic isn't just in the tools; it's in the rules the AI follows. The researchers taught the AI four main "laws" of Jiangnan garden design:
- Water is King: Everything revolves around the water.
- The Mystery of the Winding Path: Never show the whole garden at once. Make the visitor walk, turn, and discover.
- Miniature Nature: Use rocks and plants to represent huge mountains and forests in a tiny space.
- Asymmetrical Balance: Don't make it perfectly symmetrical (like a French palace). Make it look naturally balanced, like a painting.
4. What Can You Do With It?
The team built a tool inside Unity (a popular game engine) where anyone can type a sentence and see a 3D garden appear instantly.
- For Gamers & Filmmakers: You can instantly generate beautiful backgrounds for your video games or movies.
- For Tourists: You can create a "virtual tour" of a garden you've never visited.
- For Real Gardeners: The system can even print out a 2D map (a blueprint) that real construction workers can use to build an actual physical garden in a park or backyard.
The Big Picture
Before this, making a digital Jiangnan garden was like trying to paint the Mona Lisa with a crayon—it took too long and required too much skill. GardenDesigner gives you a paintbrush that knows how to paint the Mona Lisa for you, as long as you tell it what you want to see. It preserves ancient cultural art and makes it accessible to everyone, turning complex history into a simple text message.
