Determining Support for Vertex Tweening

To determine if Microsoft® Direct3D® supports vertex tweening, check for the D3DVTXPCAPS_TWEENING flag in the VertexProcessingCaps member of the D3DCAPS8 structure. The following code example uses the Direct3DDevice8.GetDeviceCaps method to determine if tweening is supported.

'
' This example assumes that d3dDevice
' is a valid Direct3DDevice object.
'
Dim d3dCaps As D3DCAPS8

d3dDevice.GetDeviceCaps d3dCaps
If 0 <> (d3dCaps.VertexProcessingCaps & D3DVTXPCAPS_TWEENING) Then
    //Vertex tweening is supported.
End If
