1. Traditional 3D Models: What They Are and Their Limitations
1.1 Where 3D Models Shine
For decades, 3D models have been an invaluable tool in architecture, design, and real estate marketing. Static or partially interactive, these models display properties with photorealistic visuals that help stakeholders visualize spaces well before construction completes. A few typical use cases:
- Architectural Previews: Providing clients or investors with a sense of shape, layout, and aesthetics.
- Marketing Assets: Off-plan renderings are widely used in brochures or websites, clarifying apartment layouts or office building silhouettes.
- Basic Virtual Walkthroughs: Some 3D modeling solutions add partial interactivity, letting users rotate or zoom in on designs.
While 3D models remain indispensable for early concept approvals and marketing materials, they are limited in scope. Once created, a 3D model is largely static—it doesn’t automatically update to reflect real-world progress, operational data, or changes in occupant use. Moreover, the user’s interaction with the model tends to be minimal: viewing or rotating it from a few angles.
1.2 Shortcomings of Traditional 3D Rendering
As the construction, real estate, and event industries explore more immersive presentations, purely static 3D models can’t meet growing demands. They often lack:
- Real-Time Data Integration: No direct link to sensors or occupant analytics, so they can’t show “live” changes in conditions or usage.
- Interactivity & Scalability: Typically designed for limited exploration; bigger or multi-phase developments can make 3D files cumbersome or outdated.
- Operational Context: Where do we see energy usage, traffic flow, or occupant satisfaction? Traditional 3D visualizations simply can’t incorporate these insights.
