Engineering Contradiction Analysis
1Ease of manufacture
If traditional methods are used to construct three-dimensional virtual objects in computer-generated environments, then the objects can be created with high precision and complexity, but the process becomes extremely time-consuming and complex for users
Solution Approach 1:
The patent uses photogrammetry to capture images of real-world objects and automatically generates three-dimensional virtual models by processing these images. This copying approach allows users to create complex virtual objects quickly by simply photographing real objects, eliminating the need for manual modeling while preserving geometric accuracy and detail
Solution Approach 2:
The patent replaces manual mechanical modeling operations with automated computational image processing. Instead of requiring users to manually construct three-dimensional models through complex interface operations, the system automatically generates virtual objects from captured images using photogrammetric algorithms, significantly reducing time and complexity
2Manufacturing precision
If detailed three-dimensional virtual objects are constructed manually, then high precision and complexity are achieved, but the operation becomes complex and difficult for beginners
Solution Approach 1:
By copying geometric information directly from real-world objects through photography, the system achieves high construction precision without requiring users to understand complex modeling operations. The photogrammetric process automatically extracts accurate three-dimensional geometry from multiple two-dimensional images
Solution Approach 2:
The system performs automatic object recognition and model generation without requiring user intervention in the complex modeling process. The software independently handles image processing, feature detection, and three-dimensional reconstruction, making the operation simple while maintaining high precision
3Productivity
If automated voxel generation from real-world objects is implemented, then creation time is reduced and ease of use is improved, but the complexity of the system increases
Solution Approach 1:
The patent introduces a photogrammetry processing system as an intermediary between simple image capture and voxel generation. This intermediary automatically handles the complex tasks of three-dimensional reconstruction and mesh processing, converting captured images into voxel representations without requiring users to understand the underlying complexity
Data Source
AI summary
A three-dimensional computer-generated environment can be presented to a user. The user can create a virtual representation of a real-world object within the computer-generated environment by directing an input device towards the real-world object and tracing contours of the real-world object. The virtual representation can include voxels. The user can edit the virtual representation or create a new virtual object formed of voxels by depositing or removing voxels at virtual locations within the computer-generated environment based on selection inputs, release inputs, and optionally movement inputs detected by the input device. In some cases, the user can provide inputs via another input source, such as a hand of the user, that are detected by additional sensors or devices.
