PointList | Renders the vertices as a collection of isolated points. This value is unsupported for indexed primitives. |
|
LineList | 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. |
|
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. |
|
TriangleFan | Renders the vertices as a triangle fan. |
Remarks
A triangle strip renders the vertices as a series of connected triangles. Culling is removing a face from the list of faces to render. Faces can be culled using a number of techniques including: back face, view frustum, and occlusion culling.
Using triangle strips or triangle fans is often more efficient than using triangle lists because fewer vertices are duplicated.
