Question about Directx to Xna conversion
hi guys I am tring to convert a directx vertex structure for a grass shared to XNA, but cannot figure out? can any of the XNA team Help?
Friend Structure GrassVertex
' Methods
Shared Sub New()
GrassVertex.Format = (VertexFormats.Texture3 Or VertexFormats.Position)
End Sub
' Fields
Public Shared ReadOnly Format As VertexFormats
Public position As Vector3
Public u0 As Single
Public u1 As Single
Public v0 As Single
Public v1 As Single
End Structure
