As a result of step 3, your graphics card will know where to find what data inside each vertex. In this example, it will pass bytes 0 to 11 (3 floats) to the POSITION0 input of the vertex shader. Bytes 12 to 15 (1 float) will be passed to the COLOR0 input of the vertex shader. The Complete MyVertexPositionColor Struct This is what you should have at the moment: public struct MyVertexPositionColor { public Vector3 Position; public Color Color; public MyVertexPositionColor(Vector3 position, Color color) { Position = position; Color = color; } public static readonly VertexElement[] VertexElements = { new VertexElement(0, 0, VertexElementFormat.Vector3, VertexElementMethod.Default, VertexElementUsage.Position, 0), new VertexElement(0, sizeof(float)*3, VertexElementFormat.Color, VertexElementMethod.Default, VertexElementUsage.Color, 0), }; public static readonly int SizeInBytes = sizeof(float) * (3 + 1); }

With the struct ready to be used, you can define the vertices and turn them into a VertexBuffer stream, as explained in recipe 5-4. This time, you re using your own vertex format: private void InitVertices() { myVertexDeclaration = new VertexDeclaration(device, MyVertexPositionColor.VertexElements); MyVertexPositionColor[] vertices = new MyVertexPositionColor[3]; int i = 0; vertices[i++] = new MyVertexPositionColor(new Vector3(1, 1, -1), Color.Red); vertices[i++] = new MyVertexPositionColor(new Vector3(3, 5, -1), Color.Green); vertices[i++] = new MyVertexPositionColor(new Vector3(5, 1, -1), Color.Blue);

vertBuffer = new VertexBuffer(device, MyVertexPositionColor.SizeInBytes * vertices.Length, BufferUsage.WriteOnly); vertBuffer.SetData<MyVertexPositionColor>(vertices, 0, vertices.Length); } The first line creates the VertexDeclaration, which is nothing more than what you coded in step 3 earlier. It will be passed to your graphics card before rendering the triangle. The middle part of the method creates an array holding three MyVertexPositionColors, defining another silly triangle. For each vertex, you store the position and color. To create a VertexBuffer based on the array, you need to specify how many bytes one vertex occupies, so you pass in MyVertexPositionColor.SizeInBytes. When it comes to drawing this triangle from the VertexBuffer, you need this code, as explained in recipe 5-4: basicEffect.Begin(); foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Begin(); device.VertexDeclaration = myVertexDeclaration; device.Vertices[0].SetSource(vertBuffer, 0, MyVertexPositionColor.SizeInBytes); device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1); pass.End(); } basicEffect.End(); Before you render the triangles, you need to pass the VertexElements to the graphics card so it knows how to correctly separate the byte stream into useful data.

As a second example, you will create a new vertex format, capable of storing a Position, a Texture coordinate, and an extra Vector4. This allows you to pack four extra values with every vertex sent from your XNA project to your vertex shader; Figure 5-28 shows two of such vertices as a byte stream. This is the new struct, where you again can identify the three main parts: public struct MyCustomVertexFormat { public Vector3 Position; public Vector2 TexCoords; public Vector4 Extra; public MyCustomVertexFormat(Vector3 Position, Vector2 TexCoords, Vector4 Extra) { this.Position = Position; this.TexCoords = TexCoords; this.Extra = Extra; }

The top part allows each vertex to store a Position, a Texture coordinate, and an extra Vector4. Next, you link them to your vertex shader input. You indicate the first Vector3 should be linked to the POSITION0 semantic. Because it is the first data item, it can be found at byte 0 (the second argument). The second line indicates that the Vector2 containing the Texture coordinate should be linked to the TEXCOORD0 input of the vertex shader. The Position takes up three floats, so the Texture coordinate can be found at position sizeof(float)*3 = 12, which can be verified in Figure 5-28. The third line links the additional Vector4 to another TEXTURE semantic, because these can be used to pass extra data. Since the TEXTURE0 intrinsic is already used, you link it to the TEXTURE1 intrinsic by specifying 1 as the last argument. This Vector4 is preceded by a Position and Texture coordinate data, occupying three and two floats, so the extra Vector4 can be found at byte number sizeof(float)*(3+2) = 20, which again is shown in Figure 5-28.
