PrimitiveType Enumeration

Defines how vertex data is ordered.

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

Syntax

public enum PrimitiveType

Members

  Member name Description
TriangleList The data is ordered as a sequence of triangles; each triangle is described by three new vertices. Back-face culling is affected by the current winding-order render state.
TriangleStrip The data is ordered as a sequence of triangles; each triangle is described by two new vertices and one vertex from the previous triangle. The back-face culling flag is flipped automatically on even-numbered triangles.
LineList The data is ordered as a sequence of line segments; each line segment is described by two new vertices. The count may be any positive integer.
LineStrip The data is ordered as a sequence of line segments; each line segment is described by one new vertex and the last vertex from the previous line seqment. The count may be any positive integer.

Remarks

A strip is often more efficient than a list because fewer vertices are duplicated.
