Three-dimensional building management system visualization

The patent transforms the standard two-dimensional grid view into a three-dimensional building model that visually represents rooms, floors, and spatial relationships. This dimensional change allows users to perceive correlations between neighboring rooms and floors through spatial proximity and visual connectivity, directly addressing the loss of correlation information while maintaining manageable complexity through intuitive visualization.

The patent creates a virtual three-dimensional copy of the building model that can be rendered and manipulated in a web browser without requiring expensive proprietary hardware or software. The system uses standard web technologies to replicate the visualization capabilities previously available only through costly proprietary solutions, making comprehensive building model rendering accessible and practical.

The patent segments the building model data into manageable components and processes them incrementally in the browser using WebGL and JavaScript. Instead of loading and processing the entire model at once, the system divides the rendering task into smaller segments that can be processed efficiently, reducing browser latency and preventing freezing while maintaining accessibility through standard web browsers.

The patent implements partial loading and progressive rendering of building data, where essential elements are displayed first and additional details are loaded as needed. The system processes and renders critical building information immediately while deferring less critical data, achieving comprehensive representation without requiring all data to be processed simultaneously, thus improving processing speed and reducing latencies.
