2D to 3D Scene Conversion via Touch Gesture Plane Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for creating three-dimensional (3D) computer graphics representations from two-dimensional (2D) drawings or images are either fully automatic and inflexible, or require staged processes that do not allow for user control or input in vector formats, limiting the complexity and controllability of the output scene.
Innovation Solution
A system and method that enables users to construct a 3D scene simultaneously with inputting 2D drawings or images in raster or vector form, using a graphical user interface with a touch-sensitive display to arrange and project 2D planes in virtual 3D space, allowing for rotation and modification of content using gestures and tools like 'pinching for parallel' and 'hinge for angled' interfaces.

Engineering Contradiction Analysis
1Extent of automation
If automatic techniques are used to create 3D representation from 2D images, then the process is automated, but the output geometry is mathematically inferred and not controllable by the user
Solution Approach 1:
The system allows users to directly manipulate and position 2D images in 3D space through intuitive touch interface gestures, making the system serve the user's creative intent rather than forcing mathematical inference. Users can pinch to create parallel planes, use hinge gestures for rotation, and directly place images where they want them in the 3D scene.
Solution Approach 2:
The patent introduces an intermediary touch-sensitive display interface that translates simple user gestures into complex 3D scene construction operations. This intermediary layer bridges the gap between simple user input and sophisticated 3D rendering, allowing users to control the geometry directly without complex manual manipulation.
2Stability of the object's composition
If staged processes are used where 3D geometry is constructed first and then image data is affixed, then the process is systematic, but it is not an integrated process and lacks flexibility
Solution Approach 1:
The patent merges the 3D geometry construction and image data affixing operations into a single integrated process. Users simultaneously define the 3D spatial arrangement and place 2D images on the appropriate planes during the same interactive session, eliminating the need for separate staged operations and enabling flexible adjustments at any point.
Solution Approach 2:
The system dynamically adjusts the 3D scene configuration as users interact with it. The geometry and image placement are not fixed in separate stages but can be continuously modified and repositioned during the same workflow, allowing the scene to adapt to user needs in real-time.
3Manufacturing precision
If conventional systems like 'Tour into the picture' are used to augment raster images with depth values, then depth information is added, but the system only works with raster format and not vector format
Solution Approach 1:
The patent creates a universal interface that accepts both raster and vector image formats through the same touch interaction mechanism. The system treats different image formats uniformly, allowing users to pinch, rotate, and position both raster and vector images in the 3D space using identical gestures and operations.
Solution Approach 2:
The system changes the parameter of image format acceptance from restricted to inclusive. By implementing a format-agnostic projection and positioning system, it can handle various image types (raster, vector, multiple layers) without requiring different processing workflows, thereby expanding versatility.
4Device complexity
If conventional systems use restricted output scenes with specific mesh structures, then the implementation is simplified, but the output scene complexity is limited
Solution Approach 1:
The patent segments the 3D scene into multiple independent 2D planes that can be individually manipulated. Each plane can be positioned, rotated, and scaled independently through touch gestures, allowing users to construct complex scenes from simple modular units while maintaining implementation simplicity through consistent interaction patterns.

AI summary
A computer-implemented method of and system for converting a two-dimensional drawing into a navigable three-dimensional computer graphics representation of a scene that includes inputting the two-dimensional drawing, embedding some portion of the two-dimensional drawings onto one or more two-dimensional planes, arranging the two-dimensional planes in a virtual three-dimensional space; and outputting the arranged two-dimensional planes into the three-dimensional computer graphics representation of the scene.
