User-friendly graph editing for procedural modeling of buildings.

Area of Science:

• Computer Graphics
• Computational Geometry
• Digital Art

Background:

• Traditional 3D modeling workflows can be restrictive for artists.
• Existing methods may not seamlessly integrate complex geometric operations.
• A need exists for intuitive, workflow-compatible procedural content creation tools.

Purpose of the Study:

• To propose a novel rule-based editing metaphor for 3D building creation.
• To enable artists to intuitively generate and modify architectural models.
• To leverage graph-based representations for enhanced modeling flexibility.

Main Methods:

• Representing the rule base as a directed acyclic graph (DAG).
• Shifting the development paradigm to rule-based representations.
• Developing a visual interface for rule creation, editing, and workflow control.
• Implementing tools for Boolean operations and local controlling operators.

Main Results:

• Artists can intuitively create buildings without altering their existing workflows.
• The system supports visual editing and connection of rules to control the generation process.
• New commands, such as Boolean operations, are easily integrated into the artist's toolbox.
• The approach facilitates model verification and editing via graph rewriting.

Conclusions:

• The proposed rule-based editing metaphor offers an intuitive and flexible approach to 3D architectural modeling.
• This method enhances artistic control and expands the possibilities for procedural content generation.
• The DAG representation and graph rewriting techniques open avenues for advanced model manipulation and verification.
