Seam Resolution in 3D Texture Mapping via UV Remapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying two-dimensional images to three-dimensional structures often result in seams, especially when the three-dimensional geometry is customized or unknown in advance, leading to incomplete, inaccurate, or seam-ridden textures.
Innovation Solution
A method involving the creation of a seam map in UV space, where control circuitry identifies sub-images and defines seam connectivity, allowing for remapping of objects to avoid seams by generating UV locations and applying seam offsets to ensure seamless texture application.

1Area of stationary object
If a two-dimensional image is wrapped around a three-dimensional structure, then the texture coverage is improved, but seams appear on the three-dimensional geometry
Solution Approach 1:
The patent divides the two-dimensional image into multiple sub-images corresponding to different portions of the three-dimensional structure. By segmenting the texture mapping into multiple manageable parts, the system can process and adjust each sub-image independently to minimize seam visibility while maintaining comprehensive texture coverage.
Solution Approach 2:
The patent introduces UV space as an additional dimensional framework for mapping two-dimensional images to three-dimensional structures. By operating in this extended UV coordinate space, the system can define seam connectivity and perform remapping operations that resolve seams in ways not possible with traditional single-plane mapping approaches.
2Adaptability or versatility
If the three-dimensional geometry is customized or unknown in advance, then the adaptability is improved, but seam resolution becomes difficult
Solution Approach 1:
The patent performs preliminary actions by defining seam connectivity in UV space before the actual texture application. By pre-establishing the connectivity relationships and creating a seam map in advance, the system prepares the mapping framework to handle customized or unknown geometries, enabling seamless remapping when decals or objects are applied later without requiring advance knowledge of the final geometry.
Solution Approach 2:
The patent implements feedback mechanisms by checking whether object V locations fall within seam boundaries on the two-dimensional image. When seams are detected, the system automatically remaps the affected objects or decals to resolve the seams, creating a closed-loop process that continuously monitors and corrects seam issues during the texture application process.
3Adaptability or versatility
If decals are applied to customize three-dimensional geometry, then the versatility is improved, but seams and inaccuracies appear in the texture mapping
Solution Approach 1:
The patent introduces UV space and seam maps as intermediary frameworks between the decal application process and the final texture mapping. This intermediary layer allows decals to be placed and customized on the three-dimensional structure without directly creating seams, as the UV coordinate system and seam connectivity definitions mediate the mapping process to ensure accurate, seam-free integration of custom decals into the overall texture.

AI summary
Systems and methods are provided for resolving seams in computer graphics when a two-dimensional image is applied to a three-dimensional structure. The method can include providing a two-dimensional image in a UV space, identifying at least one sub-image on the two-dimensional image, defining a seam connectivity for the two-dimensional image in the UV space, and remapping the location of an object on the two-dimensional image when the location of the object is within at least one seam boundary of the seam map.
