IndexBuffer Class
XNA Game Studio 4.0
Describes the rendering order of the vertices in a vertex buffer.
Namespace: Microsoft.Xna.Framework.Graphics
Assembly: Microsoft.Xna.Framework.Graphics (in microsoft.xna.framework.graphics.dll)
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; it associates a user-created vertex buffer of type VertexPositionNormalTexture with vertex stream 0 (zero) of the graphics device.
// Initialize the vertex buffer, allocating memory for each vertex. vertexBuffer = new VertexBuffer(graphics.GraphicsDevice, vertexDeclaration, points, BufferUsage.None); // Set the vertex buffer data to the array of vertices. vertexBuffer.SetData<VertexPositionColor>(pointList);
