Interpretation of Vertices |
point |
each vertex describes the location of a point |
line strip |
series of connected line segments; each vertex
after first describes the endpoint of next segment |
line loop |
same as line strip but final segment added from
final vertex to first vertex |
separate line |
each pair of vertex describes a line segment |
polygon |
line loop formed by vertices describes the boundary
of a convex polygon |
triangle strip |
each vertex after the first two describes a triangle
given by that vertex and the previous two |
triangle fan |
each vertex after the first two describes a triangle
given by that vertex, the previous vertex, and the
first vertex |
separate triangle |
each consecutive triad of vertices describes a triangle |
quadrilateral strip |
each pair of vertices after the first two describes
a quadrilateral given by that pair and the previous pair |
independent quad |
each consecutive group of four vertices describes
a quadrilateral |
