    D3DPT_LINELIST      = 2
    D3DPT_LINESTRIP     = 3

End Enum

Constants

D3DPT_POINTLIST
Renders the vertices as a collection of isolated points.
D3DPT_LINELIST
Renders the vertices as a list of isolated straight line segments. Calls using this primitive type fail if the count is less than 2 or is odd.
D3DPT_LINESTRIP
Renders the vertices as a single polyline. Calls using this primitive type fail if the count is less than 2.
D3DPT_TRIANGLELIST
Renders the specified vertices as a sequence of isolated triangles. Each group of three vertices defines a separate triangle.

Backface culling is affected by the current winding-order render state.

D3DPT_TRIANGLESTRIP
Renders the vertices as a triangle strip. The backface-culling flag is automatically flipped on even-numbered triangles.
D3DPT_TRIANGLEFAN
Renders the vertices as a triangle fan.

Remarks

Using triangle strips or fans is often more efficient than using triangle lists because fewer vertices are duplicated. For more information see Triangle Strips and Triangle Fans.
