Meshning

Meshning is a term used in computer graphics and computational geometry to describe a method for constructing a unified mesh by fusing multiple input meshes through alignment, fusion, and adaptive remeshing, with emphasis on maintaining consistent topology and element quality.

The term blends the word mesh with a process-oriented suffix and appears mostly in discussions of exploratory design, experimental toolchains, and non-standard workflows rather than formal standards. It is sometimes used to distinguish a fusion-based approach from traditional single-source remeshing.

A typical meshning workflow includes several stages: registering input meshes to a common coordinate frame, performing a fusion step that merges overlapping surfaces and resolves conflicts, and applying local remeshing to improve element shapes. Attribute transfer, such as textures or physical properties, may accompany the fusion, followed by validation against quality metrics like element aspect ratio and dihedral angle to ensure the result is suitable for downstream tasks.

Variants and methods of meshning vary by application. Surface meshning targets triangulated or polygonal surfaces, while volumetric meshning aims to create solid mesh representations. Multi-resolution or hierarchical meshning combines coarse and fine regions to balance accuracy and performance, often incorporating feature-preserving smoothing and topology optimization techniques.

Applications span computer-aided design, digital fabrication, and finite element analysis, where multiple assets or scans must be merged into a single coherent mesh. It is also used in terrain modeling and visual effects pipelines where consistency across assets is important.

Challenges include maintaining manifold topology, preserving sharp features, avoiding non-manifold edges, and managing computational cost. As a non-standard term, its exact meaning can vary across communities, and no universal protocol governs meshning.
