3D Sketch Region of Interest Control Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces for 3D modeling lack intuitiveness and ease of use for sketching in three-dimensional virtual spaces, making it difficult for users to efficiently generate and manipulate 3D models.
Innovation Solution
An interfacing method that determines a region of interest in a 3D virtual space based on user input, allows for the control of the region's position through rotation and movement, and generates sketch lines within this region based on further user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional 2D user interface is used for 3D sketching, then the interface is simple and easy to implement, but the intuitiveness and ease of operation for 3D sketching is poor
Solution Approach 1:
The patent transitions from traditional 2D interface interactions to 3D spatial interactions by allowing users to select and manipulate regions of interest directly in the 3D virtual space. The interface enables users to define regions of interest through 3D space selection, rotate and move these regions along 3D axes, and generate sketch lines within the defined 3D region, thereby providing intuitive 3D sketching capabilities.
2Measurement precision
If the entire 3D space is displayed at once, then the overview is complete, but the precision for sketching in specific regions is insufficient
Solution Approach 1:
The patent divides the 3D virtual space into multiple regions of interest that can be selectively displayed and manipulated. Users can define specific regions of interest within the 3D space, and the system displays and enables sketching operations only within the selected region, thereby providing high precision for sketching while maintaining the ability to navigate the complete 3D space through region selection.
3Ease of operation
If multiple sketch lines are generated without region selection, then the workflow is simple, but the organization and manipulation of sketch lines is difficult
Solution Approach 1:
The patent introduces the concept of a 'region of interest' as an intermediary structure that organizes sketch lines. When users define a region of interest in 3D space, all sketch lines generated within that region are automatically associated with it. This intermediary region structure enables users to selectively manipulate, rotate, and move groups of sketch lines together, simplifying the organization and manipulation process.

AI summary
Disclosed are an interfacing method and an apparatus for three-dimensional (3D) sketch. According to an example embodiment, the interfacing method for sketching in a virtual space of three dimensions includes determining a surface including an area in which a first user input is received in the virtual space to be a region of interest, controlling a position of the region of interest in the virtual space based on a second user input on the region of interest, and generating at least one sketch line belonging to the region of interest based on a third user input.
