3D Model Editing via 2D Vector Overlay on UV Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D modeling techniques are time-consuming and tedious when trying to individually alter or color separate areas of a 3D model that are not part of a mesh group, requiring the creation of multiple 3D models.
Innovation Solution
A system and method using 2D vectors, such as SVG, to create editable configurations of 3D models by dynamically forming virtual mesh groups on the 3D model, allowing for individual editing of areas without requiring them to be independent mesh groups, through overlaying 2D vectors on UV maps and applying color or texture transformations.

Engineering Contradiction Analysis
1Ease of operation
If multiple 3D models are created to individually edit separate areas, then individual editing capability is improved, but time consumption and model complexity increase
Solution Approach 1:
The patent segments the 3D model into multiple editable regions by creating virtual mesh groups from 2D vector geometries overlaid on the UV map. Each vector geometry defines a specific editable region, allowing individual manipulation without creating separate 3D models. This segmentation enables selective editing of model portions while maintaining a single unified 3D model structure.
Solution Approach 2:
The patent introduces 2D vector geometries as an intermediary layer between the UV map and the 3D model surfaces. These vectors serve as mediators that define editable regions by mapping onto the UV coordinates, allowing users to create virtual mesh groups that correspond to specific model areas without modifying the underlying 3D model structure or creating multiple models.
2Adaptability or versatility
If separate 3D models are created for different mesh groups, then individual area manipulation is enabled, but device complexity and processing requirements increase
Solution Approach 1:
The patent solves the complexity problem by working in the 2D UV space rather than directly in 3D model space. By overlaying 2D vector geometries on the UV map, the system defines editable regions in two dimensions, which then map to the corresponding 3D surfaces. This dimensional reduction simplifies the complexity management while maintaining the ability to manipulate individual model areas.
3Ease of operation
If traditional mesh grouping is used to enable individual editing, then editing flexibility is improved, but the requirement for physical grouping limits versatility
Solution Approach 1:
The patent implements dynamic virtual mesh groups that can be created, modified, and removed without permanently altering the 3D model structure. Unlike traditional mesh grouping that requires permanent physical segmentation, the vector-based approach allows flexible, temporary grouping of model areas for editing purposes. The virtual groups are dynamically generated from vector geometries and can be adjusted at any time without committing structural changes to the model.

AI summary
A system and method is provided for creating editable configurations of 3D models. A 2D vector outlining a plurality of geometries is created and overlaid on the UV map of a 3D model. The 2D vector is used to create a plurality of virtual mesh groups outlined by the 2D vector, on the underlying mesh group of the 3D model. At least one mesh is selected from the plurality of virtual mesh groups for editing, thereby creating a plurality of editable configurations of the 3D model. The virtual mesh group is edited by applying any one of coloring, imaging, and texturing operations. The editing a virtual mesh group for applying a color transformation is replaced by applying the color transformation to the 2D vector and rasterizing the 2D vector into an image and applying the image as a texture on the UV map.
