Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D modeling technologies lack seamless navigation capabilities, such as orbiting, viewing orthographic floor plans, and walking through models with smooth transitions, which are essential for applications like real estate documentation and space modification.
Innovation Solution
A system that allows users to orbit around a model on a specific axis, view an orthographic floor plan, and walk through it while maintaining a fixed height, utilizing input devices and 3D rendering engines for smooth transitions between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users can switch between orbiting, floor plan, and walking modes in 3D models, then user interaction and navigation capability are improved, but system complexity increases
Solution Approach 1:
The system implements a unified 3D viewing platform that integrates multiple navigation modes (orbiting, floor plan view, and walking through) within a single application framework. This multi-functional approach allows one system to serve multiple user needs and interaction styles, improving adaptability without requiring separate applications for each viewing mode.
Solution Approach 2:
The system dynamically switches between different navigation modes based on user input and contextual requirements. The camera transformation parameters and rendering settings are adjusted in real-time to transition smoothly between orbiting, floor plan, and walking modes, enabling the system to adapt its behavior dynamically rather than requiring rigid, separate systems for each mode.
2Ease of operation
If smooth transitions between navigation modes are implemented, then user experience is improved, but processing requirements and system complexity increase
Solution Approach 1:
The system pre-calculates and prepares transformation parameters for mode transitions before executing them. By anticipating the needed camera movements and rendering settings changes, the system can execute smooth transitions more efficiently, reducing the computational burden during actual transition execution and improving overall user experience.
Solution Approach 2:
The system introduces intermediate transition states and buffer zones between different navigation modes. Rather than abrupt switches, the system uses intermediary transformation stages that bridge the gap between modes, smoothing the transition and reducing the complexity of direct mode switching by breaking down the transition into manageable intermediate steps.
3Measurement precision
If the system maintains specific height above ground during walking mode, then navigation precision is improved, but movement flexibility is reduced
Solution Approach 1:
The system applies different height constraints locally within the walking mode navigation. Rather than enforcing a fixed height globally, the system allows height variations at specific locations or during specific actions (such as looking up or down), while maintaining the general principle of staying above ground level. This localized approach preserves navigation precision while allowing necessary movement flexibility.

AI summary
The present disclosure concerns a methodology that allows a user to “orbit” around a model on a specific axis of rotation and view an orthographic floor plan of the model. A user may view and “walk through” the model while staying at a specific height above the ground with smooth transitions between orbiting, floor plan, and walking modes.
