[SlimDX] CustomVertex ??

Recommended Posts

I've got some problems to convert the customVertex from MDX to slimDX. Is there no CustomVertex Class in slimDX ?
        _vbuffer = New VertexBuffer(GetType(CustomVertex.PositionNormalTextured), _
                            6, _dxdevice, 0, CustomVertex.PositionNormalTextured.Format, _
                            Pool.Managed)

        Dim _verts As CustomVertex.PositionNormalTextured() = CType(_vbuffer.Lock(0, LockFlags.None), CustomVertex.PositionNormalTextured())


        For x = 0 To 5
            _verts(x) = New CustomVertex.PositionNormalTextured(_vec(x), n, _tex(x).X, _tex(x).Y)
            xt += 1
        Next
        _vbuffer.Unlock()

Thanks for help

Nope, SlimDX has none built in. I think the SampleFramework has that support, but I'll let Mike chime in on that. Building vertex structs is fairly easy though, they typically work like this:

using System.Runtime.InteropServices;
using SlimDX;

[StructLayout(LayoutKind.Sequential)]
struct PositionNormalTextured
{
public Vector3 Position;
public Vector3 Normal;
public Vector2 TexCoords;

public property int Size
{
get { return 32; }
}

public property VertexFormat VertexFormat
{
return VertexFormat.Position | VertexFormat.Normal | VertexFormat.TexCoord1;
}
};


(Written completely off memory so be prepared for minor errors.)

The Sample Framework right now has two vertex types if you want to use them: TransformedColoredVertex and TransformedColoredTexturedVertex. The CustomVertex class from MDX is not included because it has no direct Direct3D counterpart. It's simply a collection of vertex types that are easy to declare on your own.
