Enum TextureOptions
Resource options for textures.
[Flags]
public enum TextureOptionsFields
None = 0None. The default.
Enables resource data sharing between two or more Direct3D devices.
The only resources that can be shared are 2D non-mipmapped textures. SharpDX.Direct3D11.ResourceOptionFlags.Shared and SharpDX.Direct3D11.ResourceOptionFlags.SharedKeyedmutex are mutually exclusive. WARP and REF devices do not support shared resources. If you try to create a resource with this flag on either a WARP or REF device, the create method will return an E_OUTOFMEMORY error code. Note?? Starting with Windows?8, WARP devices fully support shared resources. ? Note?? Starting with Windows?8, we recommend that you enable resource data sharing between two or more Direct3D devices by using a combination of the SharpDX.Direct3D11.ResourceOptionFlags.SharedNthandle and SharpDX.Direct3D11.ResourceOptionFlags.SharedKeyedmutex flags instead.
Enables the resource to be synchronized by using the SharpDX.DXGI.KeyedMutex.Acquire(System.Int64,System.Int32) and SharpDX.DXGI.KeyedMutex.Release(System.Int64) APIs.
The following Direct3D 11 resource creation APIs, that take SharpDX.Direct3D11.ResourceOptionFlags parameters, have been extended to support the new flag. SharpDX.Direct3D11.Device.CreateTexture1D(SharpDX.Direct3D11.Texture1DDescription@,SharpDX.DataBox[],SharpDX.Direct3D11.Texture1D) SharpDX.Direct3D11.Device.CreateTexture2D(SharpDX.Direct3D11.Texture2DDescription@,SharpDX.DataBox[],SharpDX.Direct3D11.Texture2D) SharpDX.Direct3D11.Device.CreateTexture3D(SharpDX.Direct3D11.Texture3DDescription@,SharpDX.DataBox[],SharpDX.Direct3D11.Texture3D) SharpDX.Direct3D11.Device.CreateBuffer(SharpDX.Direct3D11.BufferDescription@,System.Nullable{SharpDX.DataBox},SharpDX.Direct3D11.Buffer) If you call any of these methods with the SharpDX.Direct3D11.ResourceOptionFlags.SharedKeyedmutex flag set, the interface returned will support the SharpDX.DXGI.KeyedMutex interface. You can retrieve a reference to the SharpDX.DXGI.KeyedMutex interface from the resource by using IUnknown::QueryInterface. The SharpDX.DXGI.KeyedMutex interface implements the SharpDX.DXGI.KeyedMutex.Acquire(System.Int64,System.Int32) and SharpDX.DXGI.KeyedMutex.Release(System.Int64) APIs to synchronize access to the surface. The device that creates the surface, and any other device that opens the surface by using OpenSharedResource, must call SharpDX.DXGI.KeyedMutex.Acquire(System.Int64,System.Int32) before they issue any rendering commands to the surface. When those devices finish rendering, they must call SharpDX.DXGI.KeyedMutex.Release(System.Int64). SharpDX.Direct3D11.ResourceOptionFlags.Shared and SharpDX.Direct3D11.ResourceOptionFlags.SharedKeyedmutex are mutually exclusive. WARP and REF devices do not support shared resources. If you try to create a resource with this flag on either a WARP or REF device, the create method will return an E_OUTOFMEMORY error code. Note?? Starting with Windows?8, WARP devices fully support shared resources.
Set this flag to enable the use of NT HANDLE values when you create a shared resource.
By enabling this flag, you deprecate the use of existing HANDLE values. When you use this flag, you must combine it with the SharpDX.Direct3D11.ResourceOptionFlags.SharedKeyedmutex flag by using a bitwise OR operation. The resulting value specifies a new shared resource type that directs the runtime to use NT HANDLE values for the shared resource. The runtime then must confirm that the shared resource works on all hardware at the specified feature level. Without this flag set, the runtime does not strictly validate shared resource parameters (that is, formats, flags, usage, and so on). When the runtime does not validate shared resource parameters, behavior of much of the Direct3D API might be undefined and might vary from driver to driver. Direct3D 11 and earlier: This value is not supported until Direct3D 11.1.
Remarks
This enumeration is used in TextureDescription.The TextureOptions must be 'None' when creating textures with CPU access flags.
