A triangle strip is a series of connected triangles, sharing vertices, allowing for faster rendering and more efficient memory usage for computer graphics. They are optimized on most graphics cards, making them the most efficient way of describing an object. There are two primary reasons to use triangle strips:

• Triangle strips increase code efficiency. After the first triangle is defined using three vertices, each new triangle can be defined by only one additional vertex, sharing the last two vertices defined for the previous triangle.
• Triangle strips reduce the amount of data needed to create a series of triangles. The number of vertices stored in memory is reduced from 3N to N+2, where N is the number of triangles to be drawn. This allows for less use of disk space, as well as making them faster to load into RAM.
