Note: If the returned string is empty, there are no problems.

Reimplemented from Ogre::RenderSystem.

◆ _initialise()

void Ogre::D3D11RenderSystem::_initialise ( )

overridevirtual

Start up the renderer using the settings selected (Or the defaults if none have been selected).

Called by Root::setRenderSystem. Shouldn't really be called directly, although this can be done if the app wants to.

Reimplemented from Ogre::RenderSystem.

◆ _createRenderWindow()

RenderWindow* Ogre::D3D11RenderSystem::_createRenderWindow	(	const String &	name,
		unsigned int	width,
		unsigned int	height,
		bool	fullScreen,
		const NameValuePairList *	miscParams = `0`
	)

virtual

Creates a new rendering window.

Remarks: This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

: After creation, this window can be retrieved using getRenderTarget().

Parameters

name	The name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
width	The width of the new window.
height	The height of the new window.
fullScreen	Specify true to make the window full screen without borders, title bar or menu bar.
miscParams	A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platforms unless indicated otherwise:

Key	Type / Values	Default	Description	Platform
title	String	RenderTarget name	The title of the window that will appear in the title bar
left	Positive integers	Centred	Screen x coordinate from left
top	Positive integers	Centred	Screen y coordinate from left
border	none, fixed, resize	resize	The type of window border (in windowed mode)
hidden	true, false	false	hide the created window
FSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Full screen antialiasing factor
gamma	true, false	false	Enable hardware conversion from linear colour space to gamma colour space on rendering to the window.
vsync	true, false	false	Synchronize buffer swaps to monitor vsync, eliminating tearing at the expense of a fixed frame rate
vsyncInterval	1, 2, 3, 4	1	If vsync is enabled, the minimum number of vertical blanks that should occur between renders. For example if vsync is enabled, the refresh rate is 60 and this is set to 2, then the frame rate will be locked at 30.
Full Screen	true, false	false	Specify whether to create the window in full screen mode
displayFrequency	Refresh rate in Hertz (e.g. 60, 75, 100)	Desktop vsync rate	Display frequency rate, for fullscreen mode
parentWindowHandle	Win32: HWND as int Linux: X11 Window as ulong Emscripten: canvas selector String ("#canvas")	0 (none)	Parent window handle, for embedding the OGRE in a child of an external window
externalWindowHandle	Win32: HWND as int Linux: X11 Window as ulong or ulong:uint:ulong (display:screen:windowHandle) or ulong:uint:ulong:ulong (display:screen:windowHandle:XVisualInfo*) OS X Cocoa: OgreGLView address as an integer. You can pass NSView or NSWindow too, but should perform OgreGLView callbacks into the Ogre manually. OS X Carbon: WindowRef as an integer iOS: UIWindow address as an integer	0 (none)	External window handle, for embedding the OGRE render in an existing window
externalGLControl	true, false	false	Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls.	OpenGL
currentGLContext	true, false	false	Use an externally created GL context. (Must be current)	OpenGL
minColourBufferSize	Positive integer (usually 16, 32)	16	Min total colour buffer size. See EGL_BUFFER_SIZE	OpenGL
windowProc	WNDPROC	DefWindowProc	function that processes window messages	Win 32
colourDepth	16, 32	Desktop depth	Colour depth of the resulting rendering window; only applies if fullScreen	Win32
FSAAHint	RenderSystem specific. Currently enables EQAA/ CSAA mode on D3D: if you want 4f8x (8x CSAA), set FSAA=4 and this to "f8"	Blank	FSAA mode hint	D3D
outerDimensions	true, false	false	Whether the width/height is expressed as the size of the outer window, rather than the content area	Win32
monitorIndex		-1		Win 32
monitorHandle		0 (none)		Win 32 (OpenGL)
enableDoubleClick	true, false	false	Enable the window to keep track and transmit double click messages.	Win32
useNVPerfHUD	true, false	false	Enable the use of nVidia NVPerfHUD	D3D
depthBuffer	true, false	true	Use depth buffer	D3D
NSOpenGLCPSurfaceOrder	-1 or 1	1	NSOpenGLCPSurfaceOrder	OSX
contentScalingFactor	Positive Float	The default content scaling factor of the screen	On IOS specifies the CAEAGLLayer content scaling factor. This can be useful to limit the resolution of the OpenGL ES backing store. For example, the iPhone 4's native resolution is 960 x 640. Windows are always 320 x 480, if you would like to limit the display to 720 x 480, specify 1.5 as the scaling factor.	OSX, iOS, Android
externalViewHandle	UIView pointer as an integer	0	External view handle, for rendering OGRE render in an existing view	iOS
externalViewControllerHandle	UIViewController pointer as an integer	0	External view controller handle, for embedding OGRE in an existing view controller	iOS
externalSharegroup	EAGLSharegroup pointer as an integer	0	External sharegroup, used to shared GL resources between contexts	iOS
CSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Coverage sampling factor	Android
maxColourBufferSize	Positive integer (usually 16, 32)	32	Max EGL_BUFFER_SIZE	Android
maxStencilBufferSize	Positive integer (usually 0, 8)	0	EGL_STENCIL_SIZE	Android
maxDepthBufferSize	Positive integer (usually 0, 16, 24)	16	EGL_DEPTH_SIZE	Android

◆ destroyRenderTarget()

void Ogre::D3D11RenderSystem::destroyRenderTarget ( const String & name )

virtual

Destroys a render target of any sort.

Reimplemented from Ogre::RenderSystem.

◆ setStencilCheckEnabled()

void Ogre::D3D11RenderSystem::setStencilCheckEnabled ( bool enabled )

virtual

Turns stencil buffer checking on or off.

Remarks: Stencilling (masking off areas of the rendering target based on the stencil buffer) can be turned on or off using this method. By default, stencilling is disabled.

Implements Ogre::RenderSystem.

◆ setStencilBufferParams()

void Ogre::D3D11RenderSystem::setStencilBufferParams	(	CompareFunction	func = `CMPF_ALWAYS_PASS`,
		uint32	refValue = `0`,
		uint32	compareMask = `0xFFFFFFFF`,
		uint32	writeMask = `0xFFFFFFFF`,
		StencilOperation	stencilFailOp = `SOP_KEEP`,
		StencilOperation	depthFailOp = `SOP_KEEP`,
		StencilOperation	passOp = `SOP_KEEP`,
		bool	twoSidedOperation = `false`,
		bool	readBackAsTexture = `false`
	)

virtual

This method allows you to set all the stencil buffer parameters in one call.

Unlike other render states, stencilling is left for the application to turn on and off when it requires. This is because you are likely to want to change parameters between batches of arbitrary objects and control the ordering yourself. In order to batch things this way, you'll want to use OGRE's Compositor stencil pass or separate render queue groups and register a RenderQueueListener to get notifications between batches.

◆ _setTexture()

void Ogre::D3D11RenderSystem::_setTexture	(	size_t	unit,
		bool	enabled,
		const TexturePtr &	texPtr
	)

virtual

Sets the texture to bind to a given texture unit.

User processes would not normally call this direct unless rendering primitives themselves.

Parameters

unit	The index of the texture unit to modify. Multitexturing hardware can support multiple units (see RenderSystemCapabilites::getNumTextureUnits)
enabled	Boolean to turn the unit on/off
texPtr	Pointer to the texture to use.

Implements Ogre::RenderSystem.

◆ _setSampler()

		Sampler &	s
	)

Implements Ogre::RenderSystem.

◆ _setAlphaRejectSettings()

void Ogre::D3D11RenderSystem::_setAlphaRejectSettings	(	CompareFunction	func,
		unsigned char	value,
		bool	alphaToCoverage
	)

virtual

Sets the global alpha rejection approach for future renders.

By default images are rendered regardless of texture alpha. This method lets you change that.

Parameters

func	The comparison function which must pass for a pixel to be written.
value	The value to compare each pixels alpha value to (0-255)
alphaToCoverage	Whether to enable alpha to coverage, if supported

Implements Ogre::RenderSystem.

◆ _setViewport()

void Ogre::D3D11RenderSystem::_setViewport ( Viewport * vp )

virtual

Sets the provided viewport as the active one for future rendering operations.

This viewport is aware of it's own camera and render target. Must be implemented by subclass.

Parameters

vp	Pointer to the appropriate viewport.

Implements Ogre::RenderSystem.

◆ _endFrame()

void Ogre::D3D11RenderSystem::_endFrame ( void )

virtual

Ends rendering of a frame to the current viewport.

Implements Ogre::RenderSystem.

◆ _setCullingMode()

void Ogre::D3D11RenderSystem::_setCullingMode ( CullingMode mode )

virtual

Sets the culling mode for the render system based on the 'vertex winding'.

A typical way for the rendering engine to cull triangles is based on the 'vertex winding' of triangles. Vertex winding refers to the direction in which the vertices are passed or indexed to in the rendering operation as viewed from the camera, and will wither be clockwise or anticlockwise (that's 'counterclockwise' for you Americans out there ;) The default is CULL_CLOCKWISE i.e. that only triangles whose vertices are passed/indexed in anticlockwise order are rendered - this is a common approach and is used in 3D studio models for example. You can alter this culling mode if you wish but it is not advised unless you know what you are doing. You may wish to use the CULL_NONE option for mesh data that you cull yourself where the vertex winding is uncertain.

Implements Ogre::RenderSystem.

◆ _setDepthClamp()

void Ogre::D3D11RenderSystem::_setDepthClamp ( bool enable )

virtual

Clamp depth values to near and far plane rather than discarding.

Useful for "shadow caster pancaking" or with shadow volumes

Reimplemented from Ogre::RenderSystem.

◆ _setDepthBufferParams()

void Ogre::D3D11RenderSystem::_setDepthBufferParams	(	bool	depthTest = `true`,
		bool	depthWrite = `true`,
		CompareFunction	depthFunction = `CMPF_LESS_EQUAL`
	)

virtual

Sets the mode of operation for depth buffer tests from this point onwards.

Sometimes you may wish to alter the behaviour of the depth buffer to achieve special effects. Because it's unlikely that you'll set these options for an entire frame, but rather use them to tweak settings between rendering objects, this is an internal method (indicated by the '_' prefix) which will be used by a SceneManager implementation rather than directly from the client application. If this method is never called the settings are automatically the same as the default parameters.

Parameters

depthTest	If true, the depth buffer is tested for each pixel and the frame buffer is only updated if the depth function test succeeds. If false, no test is performed and pixels are always written.
depthWrite	If true, the depth buffer is updated with the depth of the new pixel if the depth test succeeds. If false, the depth buffer is left unchanged even if a new pixel is written.
depthFunction	Sets the function required for the depth test.

Implements Ogre::RenderSystem.

◆ _setDepthBias()

void Ogre::D3D11RenderSystem::_setDepthBias	(	float	constantBias,
		float	slopeScaleBias
	)

virtual

Sets the depth bias, NB you should use the Material version of this.

Remarks: When polygons are coplanar, you can get problems with 'depth fighting' where the pixels from the two polys compete for the same screen pixel. This is particularly a problem for decals (polys attached to another surface to represent details such as bulletholes etc.).

: A way to combat this problem is to use a depth bias to adjust the depth buffer value used for the decal such that it is slightly higher than the true value, ensuring that the decal appears on top.

Note: The final bias value is a combination of a constant bias and a bias proportional to the maximum depth slope of the polygon being rendered. The final bias is constantBias + slopeScaleBias * maxslope. Slope scale biasing is generally preferable but is not available on older hardware.

Parameters

constantBias	The constant bias value, expressed as a value in homogeneous depth coordinates.
slopeScaleBias	The bias value which is factored by the maximum slope of the polygon, see the description above. This is not supported by all cards.

Implements Ogre::RenderSystem.

◆ _convertProjectionMatrix()

		Matrix4 &	dest,
		bool	forGpuProgram = `false`
	)

virtual

Converts a uniform projection matrix to suitable for this render system.

Remarks: Because different APIs have different requirements (some incompatible) for the projection matrix, this method allows each to implement their own correctly and pass back a generic OGRE matrix for storage in the engine.

Implements Ogre::RenderSystem.
