Renders the vertices as a list of isolated straight line segments. Calls that use this primitive type fail if the count is less than two or is odd.
LineStrip
Renders the vertices as a single polyline. Calls that use this primitive type fail if the count is less than two.
PointList
Renders the vertices as a collection of isolated points. This value is unsupported for indexed primitives.
TriangleFan
Renders the vertices as a triangle fan.
TriangleList
Renders the specified vertices as a sequence of isolated triangles. Each group of three vertices defines a separate triangle. Back-face culling is affected by the current winding-order render state.
TriangleStrip
Renders the vertices as a triangle strip. The back-face culling flag is flipped automatically on even-numbered triangles.
