I have to admit you've got me confused.

Which sample in the SDK are you referring to? Have you found some code you dont understand (and want to use), or is your post outlining the code you want to find/write?

I dont know what the MDX/C# equivalent is, but there is a D3DXCreateMesh() function that you can use to allocate an empty mesh - and then fill it manually as you see appropriate.

this is a code included in DirectX help file.

[C#]

int numberVerts = 8;
short[] indices = {
0,1,2, // Front Face
1,3,2, // Front Face
4,5,6, // Back Face
6,5,7, // Back Face
0,5,4, // Top Face
0,2,5, // Top Face
1,6,7, // Bottom Face
1,7,3, // Bottom Face
0,6,1, // Left Face
4,6,0, // Left Face
2,3,7, // Right Face
5,2,7 // Right Face
};

Mesh mesh = new Mesh(numberVerts * 3, numberVerts, MeshFlags.Managed,
CustomVertex.PositionColored.Format, device);

using(VertexBuffer vb = mesh.VertexBuffer)
{
GraphicsStream data = vb.Lock(0, 0, LockFlags.None);

data.Write(new CustomVertex.PositionColored(-1.0f, 1.0f, 1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(-1.0f, -1.0f, 1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(1.0f, 1.0f, 1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(1.0f, -1.0f, 1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(-1.0f, 1.0f, -1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(1.0f, 1.0f, -1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(-1.0f, -1.0f, -1.0f, 0x00ff00ff));
data.Write(new CustomVertex.PositionColored(1.0f, -1.0f, -1.0f, 0x00ff00ff));

vb.Unlock();
}

using (IndexBuffer ib = mesh.IndexBuffer)
{
ib.SetData(indices, 0, LockFlags.None);
}




how can i render the above code in

device.BeginScene();


device.EndScene();


EDIT: These forums use 'source' and 'code' tags....
