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

Syntax

public enum SetDataOptions

	Member name	Description
	Discard	The SetData operation will discard the entire buffer. A pointer to a new memory area is returned so that the direct memory access (DMA) and rendering from the previous area do not stall.
	None	Portions of existing data in the buffer may be overwritten during this operation.
	NoOverwrite	The SetData operation will not overwrite existing data in the vertex and index buffers. Specifying this option allows the driver to return immediately from a SetData operation and continue rendering.

Dynamic geometry may be rendered on the Xbox 360 by using DrawUserPrimitives.
