T-vertices
T-vertices is a term used in computer graphics to describe a problem that can occur during mesh refinement or mesh simplification. The most common case occurs in naive implementations of continuous level of detail, where a finer-level mesh is "sewn" together with a coarser-level mesh by simply aligning the finer vertices on the edges of the course polygons. The result is a continuous mesh, however due to the nature of the z-buffer and certain lighting algorithms such as Gouraud shading, visual artifacts can often be detected.〔(Frequent Mesh Problems, www.cs.princeton.edu )〕 Some modeling algorithms such as subdivision surfaces will fail when a model contains T-vertices. == References ==
