IDirect3DRM2
Applications use the methods of the IDirect3DRM2 interface to create Direct3DRM2 objects and work with system-level variables.
Applications use the methods of the IDirect3DRMDevice2 and IDirect3DRMDevice interfaces to interact with the output device. While the IDirect3DRMDevice interface, when created from the IDirect3DRM interface, works with an IDirect3DDevice Immediate Mode device, the IDirect3DRMDevice2 interface, when created from the IDirect3DRM2 interface or initialized by the IDirect3DRMDevice2::InitFromClipper, IDirect3DRMDevice2::InitFromD3D2, or IDirect3DRMDevice2::InitFromSurface method, works with an IDirect3DDevice2 Immediate Mode device. The IDirect3DDevice2 device supports the DrawPrimitive interface, as well as execute buffers, and is required for progressive meshes and for alpha blending and sorting of transparent objects.
IDirect3DRM2 supports all the methods in IDirect3DRM. In addition, the IDirect3DRM2::CreateProgressiveMesh method had been added. The IDirect3DRM2::CreateDeviceFromSurface, IDirect3DRM2::CreateDeviceFromD3D, and IDirect3DRM2::CreateDeviceFromClipper methods all create a DIRECT3DRMDEVICE2 object. The IDirect3DRM2::CreateViewport method creates a viewport on a DirectDRMDevice2 object. The IDirect3DRM2::LoadTexture and IDirect3DRM2::LoadTextureFromResource methods load a Direct3DRMTexture2 object.
To access the IDirect3DRM2 Component Object Model (COM) interface, create an IDirect3DRM object with Direct3DRMCreate, then query for IDirect3DRM2 from IDirect3DRM.
For a conceptual overview, see IDirect3DRM and IDirect3DRM2 Interfaces.
The methods of the IDirect3DRM2 interface can be organized into the following groups:
Animation CreateAnimation CreateAnimationSet Devices CreateDevice CreateDeviceFromClipper CreateDeviceFromD3D CreateDeviceFromSurface GetDevices Enumeration EnumerateObjects Faces CreateFace Frames CreateFrame Lights CreateLight CreateLightRGB Materials CreateMaterial Meshes CreateMesh CreateMeshBuilder Miscellaneous CreateObject CreateUserVisual GetNamedObject Load Tick Progressive Meshes CreateProgressiveMesh Search paths AddSearchPath GetSearchPath SetSearchPath Shadows CreateShadow Textures CreateTexture CreateTextureFromSurface LoadTexture LoadTextureFromResource SetDefaultTextureColors SetDefaultTextureShades Viewports CreateViewport Wraps CreateWrap The IDirect3DRM2 interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
AddRef QueryInterface Release IDirect3DRM2
IDirect3DRM2::AddSearchPath
Adds a list of directories to the end of the current file search path.
HRESULT AddSearchPath(
LPCSTR lpPath
);Parameters
- lpPath
- Address of a null-terminated string specifying the path to add to the current search path.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained Mode Return Values.
Remarks
For Microsoft® Windows®, the path should be a list of directories separated by semicolons (;).

IDirect3DRM2::CreateDeviceNot implemented on the Windows platform.
HRESULT CreateDevice(
DWORD dwWidth,
DWORD dwHeight,
LPDIRECT3DRMDEVICE* lplpD3DRMDevice
);IDirect3DRM2
IDirect3DRM2::CreateDeviceFromClipperCreates a Direct3DRMDevice2 Windows device by using a specified DirectDrawClipper object. An IDirect3DRMDevice2 interface works with an IDirect3DDevice2 Immediate Mode device. The IDirect3DDevice2 device supports the DrawPrimitive interface, as well as execute buffers, and is required for progressive meshes and for alpha blending and sorting of transparent objects.
HRESULT CreateDeviceFromClipper(
LPDIRECTDRAWCLIPPER lpDDClipper,
LPGUID lpGUID,
int width,
int height,
LPDIRECT3DRMDEVICE2 * lplpD3DRMDevice

Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained Mode Return Values.
Remarks
If the lpGUID parameter is NULL, the system searches for a device with a default set of device capabilities. This is the recommended way to create a Retained Mode device because it always works, even if the user installs new hardware.
The system describes the default settings by using the following flags from the D3DPRIMCAPS structure in internal device-enumeration calls:
If a hardware device is not found, the monochromatic (ramp) software driver is loaded. An application should enumerate devices instead of specifying NULL in the lpGUID parameter if it has special needs that are not met by this list of default settings.
IDirect3DRM2
IDirect3DRM2::CreateDeviceFromD3DCreates a Direct3DRMDevice2 Windows device by using specified Direct3D objects. An IDirect3DRMDevice2 interface works with an IDirect3DDevice2 Immediate Mode device.

Remarks
The child frame inherits the motion attributes of its parent. For example, if the parent is moving with a given velocity, the child frame will also move with that velocity. Furthermore, if the parent is set rotating, the child frame will rotate about the origin of the parent. Frames that have no parent are called scenes. To create a scene, specify NULL as the parent. An application can create a frame with no parent and then associate it with a parent frame later by using the IDirect3DRMFrame2::AddChild method.

Remarks
The memory associated with the image is used each time the texture is rendered, rather than the memory being copied into Direct3D Retained Mode's buffers. This allows the image to be used both as a rendering target and as a texture.
IDirect3DRM2
IDirect3DRM2::CreateTextureFromSurface
Creates a texture from a specified DirectDraw surface.
HRESULT CreateTextureFromSurface(
LPDIRECTDRAWSURFACE lpDDS,

IDirect3DRM2::LoadLoads an object.
HRESULT Load(
LPVOID lpvObjSource,
LPVOID lpvObjID,
LPIID * lplpGUIDs,
DWORD dwcGUIDs,
D3DRMLOADOPTIONS d3drmLOFlags,
D3DRMLOADCALLBACK d3drmLoadProc,
LPVOID lpArgLP,
D3DRMLOADTEXTURECALLBACK d3drmLoadTextureProc,
LPVOID lpArgLTP,
LPDIRECT3DRMFRAME lpParentFrame
);Parameters
- lpvObjSource
- Source for the object to be loaded. This source can be a file, resource, memory block, or stream, depending on the source flags specified in the d3drmLOFlags parameter.
- lpvObjID
- Object name or position to be loaded. The use of this parameter depends on the identifier flags specified in the d3drmLOFlags parameter. If the D3DRMLOAD_BYPOSITION flag is specified, this parameter is a pointer to a DWORD value that gives the object's order in the file. This parameter can be NULL.
- lplpGUIDs
- Address of an array of interface identifiers to be loaded. For example, if this parameter is a two-element array containing IID_IDirect3DRMMeshBuilder and IID_IDirect3DRMAnimationSet, this method loads all the animation sets and mesh-builder objects. Possible GUIDs must be one or more of the following: IID_IDirect3DRMMeshBuilder, IID_IDirect3DRMAnimationSet, IID_IDirect3DRMAnimation, and IID_IDirect3DRMFrame.
- dwcGUIDs
- Number of elements specified in the lplpGUIDs parameter.
- d3drmLOFlags
- Value of the D3DRMLOADOPTIONS type describing the load options.
- d3drmLoadProc
- A D3DRMLOADCALLBACK callback function used when the system reads the specified object.
- lpArgLP
- Address of application-defined data passed to the D3DRMLOADCALLBACK callback function.
- d3drmLoadTextureProc
- A D3DRMLOADTEXTURECALLBACK callback function used to load any textures used by an object that require special formatting. This parameter can be NULL.
- lpArgLTP
- Address of application-defined data passed to the D3DRMLOADTEXTURECALLBACK callback function.
- lpParentFrame
- Address of a parent Direct3DRMFrame object. This argument only affects the loading of animation sets. When an animation that is loaded from an .x file references an unparented frame in the .x file, the unparented frame's parent is set to the parent frame at lpParentFrame. However, if you use Load to load any frames in the .x file, the parent frame at lpParentFrame will not be used as the parent frame for frames in the .x file with no parent. That is, lpParentFrame is used only when you load animation sets. This value of lpParentFrame can be NULL.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained Mode Return Values.
Remarks
This method allows great flexibility in loading objects from DirectX files. See IDirect3DRM::Load for an example of how to use it.
IDirect3DRM2
IDirect3DRM2::LoadTexture
Loads a Direct3DRMTexture2 texture from the specified file. This texture can have 8, 24, or 32 bits-per-pixel, and it should be in either the Windows bitmap (.bmp) or Portable Pixmap (.ppm) P6 format.
HRESULT LoadTexture(
const char * lpFileName,
LPDIRECT3DRMTEXTURE2* lplpD3DRMTexture
);Parameters
- lpFileName
- Address of the name of the required .bmp or .ppm file.
- lplpD3DRMTexture
- Address of a pointer to be initialized with a valid IDirect3DRMTexture2 pointer if the call succeeds.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained Mode Return Values.
Remarks
LoadTexture checks whether the texture is in BMP or PPM format, which are the formats it can load. If you want to load other formats, you can add code to the callback to load the image into a D3DRMIMAGE structure and then use IDirect3DRM2::CreateTexture.
If you write your own texture callback, the LoadTexture call in the texture callback does not take a reference to the texture. For example:
HRESULT loadTextures(char *name, void *arg, LPDIRECT3DRMTEXTURE2 *tex) { return lpD3DRM2->LoadTexture(name, tex); }In this sample, no reference is taken for tex. If you want to keep a reference to each texture loaded by your texture callback, you should AddRef the texture. For example:
LPDIRECT3DRMTEXTURE2 *texarray; HRESULT loadTextures(char *name, void *arg, LPDIRECT3DRMTEXTURE2 *tex) { if (FAILED(lpD3DRM2->LoadTexture(name, tex)) { return NULL; } texArray[current++] = tex; tex->AddRef(); return tex; }IDirect3DRM2
IDirect3DRM2::LoadTextureFromResourceLoads a Direct3DRMTexture2 texture from a specified resource.

IDirect3DRM2
IDirect3DRM2::SetDefaultTextureShades
Sets the default shades to be used for an Direct3DRMTexture2 object.
HRESULT SetDefaultTextureShades(
DWORD dwShades
);Parameters

Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained Mode Return Values.
Remarks
The default search path is taken from the value of the D3DPATH environment variable. If this is not set, the search path will be empty. When opening a file, the system first looks for the file in the current working directory and then checks every directory in the search path.
D3DPATH is an environment variable that sets the default search path.
