Device.SetStreamSource Method ()

How Do I...?

  • Generate a Scene

Binds a vertex buffer to a device data stream.

Overload List

public void SetStreamSource(int, VertexBuffer, int);
public void SetStreamSource(int, VertexBuffer, int, int);

Remarks

When a flexible vertex format vertex shader is used, the stride of the vertex stream must match the vertex size, computed from the flexible vertex format (FVF). When a declaration is used, the stride should be greater than or equal to the stream size computed from the declaration.

Exceptions

InvalidCallException

The method call is invalid. For example, a method's parameter might contain an invalid value.

Generate a Scene

This example shows how to begin scene generation and draw primitives.

The SetStreamSource method binds a vertex buffer to a device data stream to create an association between the vertex data and one of several data stream ports that feed the primitive processing functions. The parameters for this method are the number of the data stream, the name of the VertexBuffer object, and the stream vertex stride.

In the following C# code example, it is assumed that the device is the rendering Device, and vBuffer is a vertex buffer filled with CustomVertex.PositionNormal data.

              [C#]
              
device.BeginScene();

device.SetStreamSource(0, vBuffer, 0);
device.VertexFormat = CustomVertex.PositionNormal.Format;
device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1);

device.EndScene();
