In computer graphics, a triangle strip is a subset of triangles in a triangle mesh with shared vertices, and is a more memory-efficient method of storing information about the mesh. They are more efficient than un-indexed lists of triangles, but usually equally fast or slower than indexed triangle lists.
When choosing a triangle for starting or continuing a triangle strip, the selection is based on a triangle's degree (i.e. the number of triangles adjacent to it), with smaller degrees being preferred. If implemented using a priority queue to quickly identify triangles that can start a new strip, the algorithm runs in linear time. [1]
One way of sharing vertex data between triangles is the triangle strip. With strips of triangles each triangle shares one complete edge with one neighbour and another with the next. Another way is the triangle fan which is a set of connected triangles sharing one central vertex.
The shortest strip for which this is possible consists of three equilateral triangles, folded at the edges where two triangles meet. Its aspect ratio – the ratio of the strip's length [ c ] to its width – is 3 ≈ 1.73 {\displaystyle {\sqrt {3}}\approx 1.73} , and the same folding method works for any larger aspect ratio.
A triangle fan is a primitive in 3D computer graphics that saves on storage and processing time. It describes a set of connected triangles that share one central vertex (unlike the triangle strip that connects the next vertex point to the last two used vertices to form a triangle), possibly within a triangle mesh .

In computational geometry, polygon triangulation is the partition of a polygonal area (simple polygon) P into a set of triangles, [1] i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P. Triangulations may be viewed as special cases of planar straight-line graphs.
