AI Analyzes Your Plan
Upload a floor plan and the neural network instantly detects walls, doors, windows, and room boundaries. Parallel inference combines multiple detection models for maximum accuracy.
Neural network powered
AI Floor Plan Renderer
Ritn3D uses trained neural networks to analyze your floor plan, detect structural elements, classify rooms by type, and render a photorealistic 3D interior model automatically. The AI handles wall detection, door and window placement, room labeling, and material assignment — delivering a complete 3D visualization without any manual 3D modeling.
How It Works
Three simple steps to your interactive 3D model
- 2
Automatic Room Classification
The AI classifies each detected room by type — kitchen, bathroom, bedroom, living room — and assigns appropriate materials, lighting, and textures based on the room's function.
- 3
Instant 3D Rendering
The rendering pipeline generates a complete 3D interior model with PBR materials, realistic lighting, and proper architectural proportions. Your model is ready to explore in seconds.
Everything You Need
Professional 3D visualization made simple
Multi-Model AI Detection
Ritn3D combines multiple detection models running in parallel to identify walls, openings, and room types. This ensemble approach delivers reliable detection across a wide range of floor plan styles and qualities.
Automatic Room Classification
The AI identifies room types based on size, shape, and spatial relationships. Kitchens, bathrooms, bedrooms, and living areas each receive appropriate materials and lighting in the generated 3D model.
PBR Material Assignment
Each surface receives physically-based rendering materials matched to its room type. Bathroom tiles, hardwood floors, painted walls, and exterior finishes are assigned automatically for a realistic result.
Intelligent Lighting
The renderer places interior light sources in each room with appropriate color temperature and intensity. Combined with HDRI-based ambient lighting, the result is a naturally lit interior visualization.
Review Before Rendering
After AI detection, you get a review step to verify and adjust the detected layout. Fix any misdetections before rendering to ensure your 3D model is accurate.
Continuous Improvement
The detection models are regularly updated to handle a wider variety of floor plan styles, line weights, and annotation patterns. Each update improves accuracy across all input types.
Frequently Asked Questions
Everything you need to know. Can’t find the answer you’re looking for? Feel free to reach out.
Detection accuracy is highest on clean, legible floor plans with clear wall lines and standard architectural symbols. The review step before rendering lets you correct any misdetections, so the final 3D model always matches your intended layout.
Ritn3D uses a combination of convolutional neural networks for wall and opening detection, along with classification models for room type identification. Multiple models run in parallel to maximize detection speed and accuracy.
Hand-drawn floor plans are not currently supported. The AI works best with clean digital floor plans, scanned architectural drawings, and PDF exports from CAD software. Professional plans with straight, consistent wall lines produce the most accurate results.
AI detection completes in seconds. The full 3D rendering pipeline typically takes 30 to 60 seconds depending on the number of rooms and complexity of the layout. The entire process from upload to interactive 3D model is under 2 minutes.
The detection models are updated periodically to improve accuracy across all floor plan types. Individual corrections you make in the review step ensure your specific model is accurate but do not directly retrain the AI in real time.
The AI works best on single-story floor plans with standard wall representations. Heavily annotated plans, 3D perspective drawings, or layouts with non-standard symbols may require more manual adjustments in the review step. Multi-story buildings are processed one floor at a time.
