verts

Verts is the plural shorthand used in geometry and computer graphics for vertex, the point where edges meet. In polygonal meshes, a vertex specifies a corner of a polygon and provides a position in 3D space, typically stored as coordinates (x, y, z). While vertices can exist individually, polygons such as triangles and quads are defined by linking vertices with edges and faces; multiple faces can share the same vertex, producing connected topology.

In practice, a mesh stores not only vertex positions but also per-vertex attributes such as normals for lighting, texture coordinates (UVs) for image mapping, and sometimes color or weight data. Rendering pipelines use vertex shaders to transform vertex positions through model-view-projection matrices before rasterization.

Vertex editing is a core operation in 3D modeling: moving a vertex reshapes surrounding geometry; actions like duplicating, merging (welding) nearby vertices, or splitting edges change topology. Subdivision algorithms add new vertices to refine surfaces and smooth detail.

Common considerations include ensuring clean topology and manifoldness for printing or simulation, avoiding duplicate vertices, and managing vertex counts for performance. In everyday software usage, 'verts' is common shorthand, while 'vertices' remains the formal plural in mathematics and technical writing.
