A triangle strip is a series of connected triangular faces. These faces are defined by three consecutive points in a point list. The first three vertices (denoted below by v1, v2, and v3), define the first triangular face. A new triangle is formed by connecting the next point with its two immediate predecessors. That is, every additional point vi defines a new triangular face with vertices vi–2, vi–1, and vi.
For example, the second triangle is defined by v2, v3, v4, the third by v3, v4, v5, etc. The following diagram illustrates a typical IFMETriangleStrip.
