3D Mesh Geometry Integration via UV Mapping and Intersection Vertices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring information between three-dimensional meshes in computer-aided design do not allow for the optimization of geometry, as they only transfer texture information without modifying the mesh geometry.
Innovation Solution
A system that maps a first mesh onto a second mesh using UV maps, calculates intersection vertices and edges, and integrates the geometry of the first mesh into the second mesh, enabling the optimization of the second mesh's geometry by transferring and combining vertices and edges.

Engineering Contradiction Analysis
1Loss of information
If UV mapping is used to transfer information between meshes, then texture information can be shared between meshes, but the geometry of the meshes cannot be modified or optimized
Solution Approach 1:
The patent merges UV mapping (for texture transfer) with mesh geometry transformation operations. The system combines the source mesh geometry with the target mesh while maintaining UV coordinate correspondence, allowing both texture information transfer and geometry modification to occur simultaneously through the merging process
Solution Approach 2:
The patent introduces UV coordinates as an intermediary that mediates between the source mesh and target mesh. By using UV coordinates as the mediating framework, the system enables both texture mapping and geometry transformation to be coordinated through the same coordinate system, resolving the contradiction between information transfer and geometry modification
2Manufacturing precision
If mesh geometry is transformed and integrated, then the second mesh can be optimized, but the complexity of the transformation process increases
Solution Approach 1:
The patent performs preliminary actions by pre-calculating UV coordinates for the source mesh vertices and pre-determining the transformation parameters before actual geometry integration. This preliminary preparation simplifies the subsequent geometry transformation process by having all necessary mapping information ready in advance
Solution Approach 2:
The patent segments the mesh transformation process into distinct operations: vertex coordinate transformation, edge transformation, face transformation, and UV coordinate mapping. Each segment handles a specific aspect of the geometry transformation, making the overall complex process more manageable and systematic

AI summary
A system for transferring a mesh into a 3D mesh, includes: a mesh receiving unit receiving a first mesh and a second mesh; a mapping unit mapping the mesh onto the 3D mesh, thereby generating a combined mesh comprising combined vertices; an intersection calculating unit calculating intersection vertices formed between the mesh and the 3D mesh in the combined mesh and further configured to add the intersection vertices to the combined mesh; and an edge calculating unit calculating combined edges between the intersection vertices and the combined vertices. The edge calculating unit is further configured to add the combined edges to the combined mesh.
