D3DDEVTYPE enumeration
Defines device types.
Syntax
typedef enum D3DDEVTYPE {
D3DDEVTYPE_HAL = 1,
D3DDEVTYPE_NULLREF = 4,
D3DDEVTYPE_REF = 2,
D3DDEVTYPE_SW = 3,
D3DDEVTYPE_FORCE_DWORD = 0x7fffffff
} D3DDEVTYPE, *LPD3DDEVTYPE;
Constants
-
D3DDEVTYPE_HAL
-
Hardware rasterization. Shading is done with software, hardware, or mixed transform and lighting.
-
D3DDEVTYPE_NULLREF
-
Initialize Direct3D on a computer that has neither hardware nor reference rasterization available, and enable resources for 3D content creation. See Remarks.
-
D3DDEVTYPE_REF
-
Direct3D features are implemented in software; however, the reference rasterizer does make use of special CPU instructions whenever it can.
The reference device is installed by the Windows SDK 8.0 or later and is intended as an aid in debugging for development only.
-
D3DDEVTYPE_SW
-
A pluggable software device that has been registered with IDirect3D9::RegisterSoftwareDevice.
-
D3DDEVTYPE_FORCE_DWORD
-
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
Remarks
All methods of the IDirect3D9 interface that take a D3DDEVTYPE device type will fail if D3DDEVTYPE_NULLREF is specified. To use these methods, substitute D3DDEVTYPE_REF in the method call.
A D3DDEVTYPE_REF device should be created in D3DPOOL_SCRATCH memory, unless vertex and index buffers are required. To support vertex and index buffers, create the device in D3DPOOL_SYSTEMMEM memory.
If D3dref9.dll is installed, Direct3D will use the reference rasterizer to create a D3DDEVTYPE_REF device type, even if D3DDEVTYPE_NULLREF is specified. If D3dref9.dll is not available and D3DDEVTYPE_NULLREF is specified, Direct3D will neither render nor present the scene.
