IndexBuffer Class

  • 项目

Describes the rendering order of the vertices in a vertex buffer.

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

Syntax

public class IndexBuffer : GraphicsResource

Example

The vertex stream and index data of the graphics device must be set before any call to DrawIndexedPrimitives. The following example sets the index data and associates a user-created vertex buffer of type VertexPositionNormalTexture with vertex stream 0 (zero) of the graphics device.

graphics.GraphicsDevice.Vertices[0].SetSource(
    vertexBuffer, 0,
    VertexPositionNormalTexture.SizeInBytes );

graphics.GraphicsDevice.Indices = lineListIndexBuffer;
