3D Model Comparison via Superposed Rendering and Transparency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for comparing 3D modeled objects lack an efficient method to visualize and interact with differences between two versions of a 3D modeled object or assembly, requiring users to switch between windows or use complex radio buttons, which is not ergonomic and limits focus on the 3D view.
Innovation Solution
A computer-implemented method that displays two 3D modeled objects superposed in the same scene, allowing user interaction through a user-interaction tool to control non-uniform variations in rendering, such as transparency, enabling real-time, seamless comparison without leaving the focus on the 3D view.

Engineering Contradiction Analysis
1Ease of operation
If users switch between windows or use radio buttons to compare 3D objects, then comparison functionality is achieved, but user ergonomics and focus on 3D view deteriorate
Solution Approach 1:
The patent merges the comparison functionality directly into the 3D view by displaying both versions of the 3D object within the same scene. Instead of requiring users to switch between separate windows or use radio buttons to toggle views, both object versions are simultaneously visible and superposed in the 3D space, allowing direct visual comparison without leaving the 3D context.
Solution Approach 2:
The patent introduces a new dimension for comparison by using transparency as a visual parameter. One version of the object is rendered with full opacity while the other is rendered with partial transparency, allowing users to perceive both versions simultaneously in the same spatial location. This dimensional approach to differentiation eliminates the need for temporal switching between views.
2Productivity
If users switch between windows to compare 3D objects, then comparison is possible, but visual focus and efficiency deteriorate
Solution Approach 1:
The patent combines multiple object versions into a single 3D scene, eliminating the need for users to switch between separate windows or views. Both object versions are displayed simultaneously in the same spatial context, allowing users to compare features directly without the time loss associated with focus changes or window switching.
Solution Approach 2:
The patent maintains continuous visual focus on the 3D scene throughout the comparison process. Users can interact with and examine both object versions without interrupting their visual attention or requiring them to shift focus to different interfaces. The comparison action continues uninterrupted within the unified 3D viewing environment.

AI summary
The disclosure notably relates to a computer-implemented method for comparing a first 3D modeled object and a second 3D modeled object. The method comprises upon manipulation of a user-interaction tool that controls at least one non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object, updating the displaying of the first 3D object and the second 3D object. The user-interaction tool is configured to be manipulated via a predetermined set of at least one action, a repetition of each respective action of the set controlling a respective non-uniform variation of the rendering of both the first 3D modeled object and the second 3D modeled object. Such a method improves the comparison of a first 3D modeled object and a second 3D modeled object that each represent a part or an assembly of parts.
