Dynamic Virtual Environment Modeler for Realistic Object Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for simulating an object in a physical room, such as overlaying a floor lamp in a photo, often result in unrealistic images due to improper lighting, orientation, and layout, and do not allow for viewing the object from different angles.
Innovation Solution
A dynamic virtual environment modeler that uses a smartphone to record a video panorama of a room and allows users to drag and drop digital representations of objects, employing 3D model data and real-time rendering to create realistic simulations of objects from various perspectives, accounting for user height and orientation.

Engineering Contradiction Analysis
1Ease of manufacture
If 2D image overlay is used to simulate objects in a room, then the implementation is simple and quick, but the realism and natural appearance deteriorates due to improper lighting, orientation, and layout
Solution Approach 1:
The patent transitions from 2D image overlay to 3D model rendering, adding a dimensional aspect that enables realistic lighting, orientation, and spatial relationships. The system uses 3D models with multiple viewpoints and lighting information to create natural-looking object simulations that respect the room's geometry and illumination conditions.
Solution Approach 2:
The patent introduces an intermediate processing layer that captures room geometry, lighting conditions, and camera parameters, then uses this information to guide the rendering of 3D objects. This intermediary step ensures that simulated objects integrate naturally with the real environment by matching lighting, shadows, and perspective.
2Productivity
If a single static image is used to display an object in a room, then the processing is simple, but the ability to view the object from different angles is lost
Solution Approach 1:
The patent replaces static image display with dynamic 3D model rendering that responds to user interactions. The system generates multiple rendered views of the same 3D object from different angles and positions, allowing users to explore the object virtually while maintaining efficient processing through pre-computed rendering techniques.
Solution Approach 2:
The patent performs preliminary rendering of 3D objects from multiple predetermined viewpoints and stores these pre-computed images. When users want to view the object from different angles, the system efficiently retrieves and displays the appropriate pre-rendered views, avoiding the need for real-time rendering calculations.
3Manufacturing precision
If 3D model data and real-time rendering are used to create realistic simulations, then the realism and viewing flexibility improve, but the device complexity and computational requirements increase
Solution Approach 1:
The patent divides the complex rendering task into separate components: room geometry capture, lighting condition analysis, 3D model data preparation, and view synthesis. Each component is processed independently and then integrated, reducing the complexity of any single processing step while maintaining overall realism.
Data Source
AI summary
An object can be simulated in an environment using a three-dimensional model of the object as viewed from a virtual camera at a position in the environment. The position in the environment can be determined using user input or through visual analysis of a video recording. Composite frames depicting the modeled object may be played back based on the orientation of the playback device.
