I'm
trying to render an animated mesh (tiny.x), I have translated the c#
sample code to vb.net but when it gets to the DrawSubset method it
throws an error:
-Run-time exception thrown : System.AccessViolationException.
I have realized that it happens an earlier error when trying to set the Device.RenderState.VertexBlend property.
The exception is:
-ErrorString:"D3DERR_INVALIDCALL"
I'm including the device intialization:
Dim DispMode As DisplayMode
DispMode = Manager.Adapters(Manager.Adapters.Default.Adapter).CurrentDisplayMode
' Define the presentation parameters
Params = New PresentParameters()
Params.Windowed = True
Params.SwapEffect = SwapEffect.Discard
Params.AutoDepthStencilFormat = DepthFormat.D16
Params.EnableAutoDepthStencil = True
Dim adapterOrdinal As Integer = Manager.Adapters.Default.Adapter
Dim flags As CreateFlags = CreateFlags.SoftwareVertexProcessing
Dim capacidad As Caps = Manager.GetDeviceCaps(adapterOrdinal, DeviceType.Hardware)
If capacidad.MaxVertexBlendMatrices >= 4 Then
flags = CreateFlags.HardwareVertexProcessing
If capacidad.DeviceCaps.SupportsHardwareTransformAndLight Then
flags = CreateFlags.HardwareVertexProcessing
End If
If capacidad.DeviceCaps.SupportsPureDevice Then
flags = flags Or CreateFlags.PureDevice
End If
Else
flags = CreateFlags.SoftwareVertexProcessing
End If
' Try to create the device
Try
xoDevice = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, Me, flags, Params)
' Define which type of vertex will be used
xoDevice.VertexFormat = VertexParams
...
Does anyone know what can be happening
Thank you so much in advance for any comments
