PrimitiveType Enumeration

Defines how data in a vertex stream is interpreted during a draw call.

Namespace: Microsoft.Xna.Framework.Graphics
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public enum PrimitiveType

Members

  Member name Description
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.
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.

Remarks

Using triangle strips or triangle fans is often more efficient than using triangle lists because fewer vertices are duplicated.
