Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Working with three-dimensional objects in a 3D space is challenging due to the freedom of interaction, which makes it difficult to achieve a desired field-of-view or precise edits, leading to a complex user experience.
Innovation Solution
A 3D editing system that dynamically sets the positions of camera and object handles to restrict interactions and simplify editing processes, by analyzing the positional elements of 3D objects and automatically adjusting camera orientations and object handles to preserve relationships and improve interactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is allowed to be positioned anywhere in 3D space with full freedom of rotation and orientation, then the flexibility of camera interaction is improved, but the complexity of achieving a desired field-of-view increases
Solution Approach 1:
The camera control system is segmented into independent components: position control, orientation control, and field-of-view control. Each component can be adjusted independently through dedicated UI controls, allowing users to achieve desired views without managing all camera parameters simultaneously. This segmentation reduces the cognitive load and operational complexity while maintaining full 3D space accessibility.
Solution Approach 2:
An intermediary control system is introduced between the user and the camera parameters. This system provides automated assistance in calculating the necessary camera adjustments to achieve a desired field-of-view, acting as a mediator that translates user intent into precise camera positioning and orientation without requiring users to manually compute all parameters.
2Adaptability or versatility
If 3D objects are allowed to be positioned and rotated anywhere in 3D space with full freedom, then the versatility of object placement is improved, but the precision required to perform desired edits increases
Solution Approach 1:
Object transformation controls are segmented into position, rotation, and scaling operations. Each transformation type has dedicated UI controls that provide intuitive manipulation methods. The system separates global object placement from local editing operations, allowing users to position objects freely while performing precise edits through specialized tools that adapt to the object's current state and position.
Solution Approach 2:
The system provides more controls and interaction methods than strictly necessary, allowing users to perform edits at different levels of precision. Users can apply coarse adjustments when exact precision is not needed, and switch to fine-tuned controls when precision is required. This partial action approach reduces the burden of maintaining high precision for all operations.
3Adaptability or versatility
If full freedom of interaction with 3D objects and cameras is provided, then the versatility of the 3D environment is improved, but the complexity of the user experience increases
Solution Approach 1:
The user interface is segmented into functional modules: camera controls, object selection, transformation tools, and property editing. Each module handles a specific aspect of interaction, reducing the overall complexity presented to the user. Users can access only the relevant controls for their current task rather than being overwhelmed by all possible interactions simultaneously.
Solution Approach 2:
The system employs universal control mechanisms that handle multiple functions through standardized interfaces. For example, a unified selection tool works for both cameras and 3D objects, and transformation controls adapt to the selected object type. This multi-functionality reduces the number of separate controls users must learn while maintaining versatile interaction capabilities.

AI summary
Disclosed is a system and associated methods for improving interactions with three-dimensional (“3D”) objects in a 3D space by dynamically defining the positioning of the handles used to control the interactions with the camera and/or the 3D objects. The system analyzes the positioning of different constructs that form the 3D objects. From the analysis, the system defines handles at different dynamically determined positions about the 3D objects. The system applies an edit from a first dynamically determined position about a particular 3D object in response to a user interaction with a first handle defined at the first dynamically determined position, and applies the edit from a second dynamically determined position about the particular 3D object in response to a user interaction with a second handle defined at the second dynamically determined position.
