Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional modeling systems face challenges in identifying and correcting defects in digital models, such as minute holes, gaps, and overlapping elements, which can lead to unsuitable models for printing, due to cumbersome error identification processes and difficulty in differentiating between defects in small regions.
Innovation Solution
The system generates intelligent viewpoints and displays digital images of a three-dimensional model with optimized viewpoints and a local color scheme to highlight defects, using bounding and medial spheres to identify exterior and interior vertices with defects, and applying graph coloring to differentiate adjacent connected vertices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional error identification tools mark individual defects with visual indicators, then defects can be located, but users must manually manipulate and inspect the model at various angles and zoom levels to identify affected regions, which is time-consuming and frustrating
Solution Approach 1:
The system automatically generates and presents optimal viewpoints that highlight defects without requiring user manipulation. The computer selects and displays viewpoints that automatically bring defects into view, allowing the model to 'serve itself' by presenting its own defects in the most identifiable manner rather than requiring active user exploration
Solution Approach 2:
The system performs preliminary analysis to identify缺陷 locations and pre-calculates optimal viewpoints before presentation to the user. By advance determining which viewpoints will best display defects, the system eliminates the need for users to manually explore various angles and zoom levels, directly presenting the most informative views
2Device complexity
If conventional tools use the same visual indicator for all defects, then implementation is simple, but users cannot differentiate between errors occurring within a small region of the three-dimensional model
Solution Approach 1:
The system assigns different visual indicators or colors to defects based on their local characteristics, such as defect type, location, or severity. This allows defects in the same region to be differentiated through localized visual properties while maintaining overall system simplicity
Solution Approach 2:
The system uses color coding to differentiate between various types of defects or to highlight the significance of different defects. By changing colors based on defect characteristics, the system provides rich differentiation information without complicating the underlying error indication mechanism
3Measurement precision
If users manually manipulate the three-dimensional model to identify defects in hollow or occluded areas, then all regions can be inspected, but the process is cumbersome and defects may remain hidden from view
Solution Approach 1:
The system generates viewpoints from multiple dimensions including internal viewpoints within hollow structures and perspectives that penetrate occluded areas. By adding these alternative viewing dimensions, the system makes previously hidden defects visible without requiring cumbersome manual manipulation to access hard-to-reach regions
4Manufacturing precision
If many defects are grouped together in a small space, then model detail is preserved, but users have difficulty identifying and differentiating between various defects
Solution Approach 1:
The system segments clustered defects into individual identifiable units by generating specific viewpoints that isolate and highlight each defect. Through strategic viewpoint selection and visual enhancement, the system separates visually overlapping defects so users can identify and address each one individually while preserving the underlying model detail

AI summary
Systems and methods are disclosed for generating viewpoints and/or digital images of defects in a three-dimensional model. In particular, in one or more embodiments, the disclosed systems and methods generate exterior viewpoints by clustering intersection points between a bounding sphere and rays originating from exterior vertices corresponding to one or more defects. In addition, in one or more embodiments, the disclosed systems and methods generate interior viewpoints by clustering intersection points between one or more medial spheres and rays originating from vertices corresponding to interior vertices corresponding to one or more defects. Furthermore, the disclosed systems and methods can apply colors to vertices corresponding to defects in the three-dimensional model such that adjacent vertices in the three-dimensional model have different colors and are more readily discernable.
