Ogre::D3D11RenderSystem::~D3D11RenderSystem ( )

Member Function Documentation

◆ _beginFrame()

void Ogre::D3D11RenderSystem::_beginFrame ( )

overridevirtual

Signifies the beginning of a frame, i.e.

the start of rendering on a single viewport. Will occur several times per complete frame if multiple viewports exist.

Implements Ogre::RenderSystem.

◆ _clearStateAndFlushCommandBuffer()

void Ogre::D3D11RenderSystem::_clearStateAndFlushCommandBuffer ( )

overridevirtual

On D3D11 calls ClearState followed by Flush().

On GL3+ it calls glFlush

Do not call this function while inside rendering internals, as it will clear the device state, thus leaving it inconsistent with what we think it is set to.

Reimplemented from Ogre::RenderSystem.

◆ _createRenderWindow()

Window* Ogre::D3D11RenderSystem::_createRenderWindow	(	const String &	name,
		uint32	width,
		uint32	height,
		bool	fullScreen,
		const NameValuePairList *	miscParams = `0`
	)

overridevirtual

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	Notes
title	Any string	RenderTarget name	The title of the window that will appear in the title bar
colourDepth	16, 32	Desktop depth	Colour depth of the resulting rendering window; only applies if fullScreen	Win32 Specific
left	Positive integers	Centred	Screen x coordinate from left
top	Positive integers	Centred	Screen y coordinate from left
depthBuffer	true, false	true	Use depth buffer	DirectX9 specific
externalWindowHandle	Win32: HWND as integer GLX: poslong:posint:poslong (display:screen:windowHandle) or poslong:posint:poslong:poslong (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. 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 specific
externalGLContext	Context as Unsigned Long	0 (create own context)	Use an externally created GL context	OpenGL Specific
parentWindowHandle	Win32: HWND as integer GLX: poslong:posint:poslong (display:screen:windowHandle) or poslong:posint:poslong:poslong (display:screen:windowHandle:XVisualInfo*)	0 (none)	Parent window handle, for embedding the OGRE in a child of an external window
contentScalingFactor	Positive Float greater than 1.0	The default content scaling factor of the screen	Specifies the CAEAGLLayer content scaling factor. Only supported on iOS 4 or greater. 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.	iOS Specific
externalViewHandle	UIView pointer as an integer	0	External view handle, for rendering OGRE render in an existing view	iOS Specific
externalViewControllerHandle	UIViewController pointer as an integer	0	External view controller handle, for embedding OGRE in an existing view controller	iOS Specific
externalSharegroup	EAGLSharegroup pointer as an integer	0	External sharegroup, used to shared GL resources between contexts	iOS Specific
Full Screen	true, false	false	Specify whether to create the window in full screen mode	OS X Specific
MSAA	Positive integer (usually 1, 2, 4, 8, 16)	1	Multisample antialiasing factor
MSAA_Quality	Depends on RenderSystem and hardware. Currently supports: 0 ... infinite number (depends on HW)	Blank	Full screen antialiasing hint
displayFrequency	Refresh rate in Hertz (e.g. 60, 75, 100)	Desktop vsync rate	Display frequency rate, for fullscreen mode
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.
border	none, fixed, resize	resize	The type of window border (in windowed mode)
outerDimensions	true, false	false	Whether the width/height is expressed as the size of the outer window, rather than the content area
useNVPerfHUD	true, false	false	Enable the use of nVidia NVPerfHUD
gamma	true, false	false	Enable hardware conversion from linear colour space to gamma colour space on rendering to the window.
enableDoubleClick	true, false	false	Enable the window to keep track and transmit double click messages.	Win32 Specific
MSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Full screen antialiasing factor	Android Specific
CSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Coverage sampling factor (https://www.khronos.org/registry/egl/extensions/NV/EGL_NV_coverage_sample.txt)	Android Specific
maxColourBufferSize	Positive integer (usually 16, 32)	32	Max EGL_BUFFER_SIZE	Android Specific
minColourBufferSize	Positive integer (usually 16, 32)	16	Min EGL_BUFFER_SIZE	Android Specific
maxStencilBufferSize	Positive integer (usually 0, 8)	0	EGL_STENCIL_SIZE	Android Specific
maxDepthBufferSize	Positive integer (usually 0, 16, 24)	16	EGL_DEPTH_SIZE	Android Specific

Implements Ogre::RenderSystem.

overridevirtual

Sets the size of points and how they are attenuated with distance.

Remarks: When performing point rendering or point sprite rendering, point size can be attenuated with distance. The equation for doing this is attenuation = 1 / (constant + linear * dist + quadratic * d^2) .

		const ColourValue &	specular,

		Real	shininess,
		TrackVertexColourType	tracking
	)

overridevirtual

Sets the surface properties to be used for future rendering.

This method sets the the properties of the surfaces of objects to be rendered after it. In this context these surface properties are the amount of each type of light the object reflects (determining it's colour under different types of light), whether it emits light itself, and how shiny it is. Textures are not dealt with here, see the _setTetxure method for details. This method is used by _setMaterial so does not need to be called direct if that method is being used.

Parameters

ambient	The amount of ambient (sourceless and directionless) light an object reflects. Affected by the colour/amount of ambient light in the scene.
diffuse	The amount of light from directed sources that is reflected (affected by colour/amount of point, directed and spot light sources)
specular	The amount of specular light reflected. This is also affected by directed light sources but represents the colour at the highlights of the object.
emissive	The colour of light emitted from the object. Note that this will make an object seem brighter and not dependent on lights in the scene, but it will not act as a light, so will not illuminate other objects. Use a light attached to the same SceneNode as the object for this purpose.
shininess	A value which only has an effect on specular highlights (so specular must be non-black). The higher this value, the smaller and crisper the specular highlights will be, imitating a more highly polished surface. This value is not constrained to 0.0-1.0, in fact it is likely to be more (10.0 gives a modest sheen to an object).
tracking	A bit field that describes which of the ambient, diffuse, specular and emissive colours follow the vertex colour of the primitive. When a bit in this field is set its ColourValue is ignored. This is a combination of TVC_AMBIENT, TVC_DIFFUSE, TVC_SPECULAR(note that the shininess value is still taken from shininess) and TVC_EMISSIVE. TVC_NONE means that there will be no material property tracking the vertex colours.

◆ _setVertexArrayObject()

void Ogre::D3D11RenderSystem::_setVertexArrayObject ( const VertexArrayObject * vao )

overridevirtual

Part of the low level rendering interface.

Tells the RS which VAO will be bound now. (i.e. Vertex Formats, buffers being bound, etc.) You don't need to rebind if the VAO's mRenderQueueId is the same as previous call.

Remarks: Assumes _setPipelineStateObject has already been called.

overridevirtual

Binds a texture to a vertex, geometry, compute, tessellation hull or tessellation domain sampler.

Remarks: Not all rendersystems support separate vertex samplers. For those that do, you can set a texture for them, separate to the regular texture samplers, using this method. For those that don't, you should use the regular texture samplers which are shared between the vertex and fragment units; calling this method will throw an exception.

		const Vector4 *	viewportSizes,
		const Vector4 *	scissors,
		uint32	numViewports,
		bool	overlaysEnabled,
		bool	warnIfRtvWasFlushed
	)

overridevirtual

When the descriptor is set to Load clear, two possible things may happen:

The region is cleared.
The whole texture is cleared. What actually happens is undefined (depends on the API). But calling "beginRenderPassDescriptor( desc, viewportSettings );" with the same descriptor but different viewports (without changing the desc) guarantees that each region is cleared:

Each time the subregion is switched

Only once (the whole texture), when the first viewport was set.

: When switching between render targets, two beginRenderPassDescriptor in a row automatically implies calls endRenderPassDescriptor. In fact this is faster to perfom than calling beginRenderPassDescriptor - endRenderPassDescriptor in pairs, because we can smartly flush only what needs to be flushed. endRenderPassDescriptor only needs to be called when no other beginRenderPassDescriptor will follow (i.e. at the end of the frame or when starting compute jobs)

Parameters

desc
anyTarget	Contains the first valid texture in mRenderPassDesc, to be used for reference (e.g. width, height, etc). Could be colour, depth, stencil, or nullptr.
mipLevel	Mip at which anyTarget is bound
viewportSize
warnIfRtvWasFlushed	See CompositorPassDef::mWarnIfRtvWasFlushed

overridevirtual

Immediately clears the whole frame buffer on the selected RenderPassDescriptor.

Prefer clearing using the LoadAction semantics in the RenderPassDescriptor. This function is provided for two reasons:

Remarks: Each render system must be able to inform the world of what options must/can be specified for it's operation.

: These are passed as strings for portability, but grouped into a structure (_ConfigOption) which includes both options and current value.

: Note that the settings returned from this call are affected by the options that have been set so far, since some options are interdependent.

overridevirtual

Number of priority config options in RenderSystem::getPriorityConfigOption.

Remarks: IMPORTANT: The return value can change after calls to setConfigOption, it can even return higher or lower values than before.

for( size_t i=0; i < rs->getNumPriorityConfigOptions(); ++i )
    rs->setConfigOption( rs->getPriorityConfigOption( i ), value );
 
// BAD:
const size_t cachedNumOptions = rs->getNumPriorityConfigOptions();

void Ogre::D3D11RenderSystem::preExtraThreadsStarted ( )

overridevirtual

Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.

Remarks

Call this from your main thread before starting your other threads (which themselves should call registerThread()). Note that if you start your own threads, there is a specific startup sequence which must be respected and requires synchronisation between the threads:

[Main thread]Call preExtraThreadsStarted
[Main thread]Start other thread, wait
[Other thread]Call registerThread, notify main thread & continue
[Main thread]Wake up & call postExtraThreadsStarted

Once this init sequence is completed the threads are independent but this startup sequence must be respected.

Implements Ogre::RenderSystem.

◆ registerThread()

void Ogre::D3D11RenderSystem::registerThread ( )

overridevirtual

Register the an additional thread which may make calls to rendersystem-related objects.

Remarks: This method should only be called by additional threads during their initialisation. If they intend to use hardware rendering system resources they should call this method before doing anything related to the render system. Some rendering APIs require a per-thread setup and this method will sort that out. It is also necessary to call unregisterThread before the thread shuts down.

Note: This method takes no parameters - it must be called from the thread being registered and that context is enough.

Implements Ogre::RenderSystem.

◆ reinitialise()

void Ogre::D3D11RenderSystem::reinitialise ( )

overridevirtual

Restart the renderer (normally following a change in settings).

Implements Ogre::RenderSystem.

◆ setClipPlane()

void Ogre::D3D11RenderSystem::setClipPlane	(	ushort	index,
		Real	A,
		Real	B,
		Real	C,
		Real	D
	)

◆ setConfigOption()

void Ogre::D3D11RenderSystem::setConfigOption	(	const String &	name,
		const String &	value
	)

overridevirtual

Sets an option for this API.

Remarks: Used to confirm the settings (normally chosen by the user) in order to make the renderer able to initialise with the settings as required. This may be video mode, D3D driver, full screen / windowed etc. Called automatically by the default configuration dialog, and by the restoration of saved settings. These settings are stored and only activated when RenderSystem::initialise or RenderSystem::reinitialise are called.

: If using a custom configuration dialog, it is advised that the caller calls RenderSystem::getConfigOptions again, since some options can alter resulting from a selection.

Parameters

name	The name of the option to alter.
value	The value to set the option to.

Implements Ogre::RenderSystem.

◆ setDrawBuffer()

bool Ogre::D3D11RenderSystem::setDrawBuffer ( ColourBufferType colourBuffer )

overridevirtual

Sets the colour buffer that the render system will to draw.

If the render system implementation or configuration does not support a particular value, then false will be returned and the current colour buffer value will not be modified.

Parameters

colourBuffer Specifies the colour buffer that will be drawn into.

Reimplemented from Ogre::RenderSystem.

◆ setLightingEnabled()

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

◆ setNormaliseNormals()

void Ogre::D3D11RenderSystem::setNormaliseNormals ( bool normalise )

◆ setShadingType()

void Ogre::D3D11RenderSystem::setShadingType ( ShadeOptions so )

◆ setStencilBufferParams()

void Ogre::D3D11RenderSystem::setStencilBufferParams	(	uint32	refValue,
		const StencilParams &	stencilParams
	)

overridevirtual

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

Remarks

The stencil buffer is used to mask out pixels in the render target, allowing you to do effects like mirrors, cut-outs, stencil shadows and more. Each of your batches of rendering is likely to ignore the stencil buffer, update it with new values, or apply it to mask the output of the render. The stencil test is:

(Reference Value & Mask) CompareFunction (Stencil Buffer Value & Mask)

The result of this will cause one of 3 actions depending on whether the test fails, succeeds but with the depth buffer check still failing, or succeeds with the depth buffer check passing too.

: 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 separate render queue groups (see RenderQueue) and register a RenderQueueListener to get notifications between batches.

Parameters

refValue	The reference value used in the comparison (dynamic)
stencilParams	The static parameters that involve more expensive state changes. Ogre dev implementors note: Should check if the stencilParams are different from before

◆ setSubroutine() [1/2]

void Ogre::D3D11RenderSystem::setSubroutine	(	GpuProgramType	gptype,
		const String &	slotName,
		const String &	subroutineName
	)

◆ setSubroutine() [2/2]

void Ogre::D3D11RenderSystem::setSubroutine	(	GpuProgramType	gptype,
		size_t	slotIndex,
		const String &	subroutineName
	)

◆ shutdown()

void Ogre::D3D11RenderSystem::shutdown ( )

overridevirtual

Shutdown the renderer and cleanup resources.

Reimplemented from Ogre::RenderSystem.

◆ unregisterThread()

void Ogre::D3D11RenderSystem::unregisterThread ( )

overridevirtual

Unregister an additional thread which may make calls to rendersystem-related objects.

Implements Ogre::RenderSystem.

◆ validateConfigOptions()

String Ogre::D3D11RenderSystem::validateConfigOptions ( )

overridevirtual

Validates the options set for the rendering system, returning a message if there are problems.

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

Implements Ogre::RenderSystem.

◆ validateDevice()

bool Ogre::D3D11RenderSystem::validateDevice ( bool forceDeviceElection = false )

overridevirtual

Some render systems have moments when GPU device is temporarily unavailable, for example when D3D11 device is lost, or when iOS app is in background, etc.

Reimplemented from Ogre::RenderSystem.

◆ validateSampleDescription()

SampleDescription Ogre::D3D11RenderSystem::validateSampleDescription	(	const SampleDescription &	sampleDesc,
		PixelFormatGpu	format
	)

overridevirtual

Returns supported sample description for requested FSAA mode, with graceful downgrading.
