LowerCpuOverhead

Optimize for low CPU overhead.

Use this on slow CPUs (i.e. older AMD CPU models) or if CPU is the bottleneck. This strategy is optimized for having a lot of different materials. Default on Desktop.

LowerGpuOverhead

Optimize for low GPU overhead.

Use this if GPU is the bottleneck. This strategy performs best when you have few materials. Do not enable this mode blindly unless you've profiled and it gives you important benefits. Default on mobile.

static

Fill the provided string and string vector with all the sub-folder needed to instantiate an HlmsPbs object with the default distribution of the HlmsResources.

These paths are dependent of the current RenderSystem.

This method can only be called after a valid RenderSysttem has been chosen.

All output parameter's content will be replaced with the new set of paths.

		String const **	outResourceGroup
	)		const

inherited

Returns the filaname & resource group a datablock was created from, and is associated with its hashed name (this was passed as in ).

Returns null ptr if not found. Note that it may also be a valid pointer but contain an empty string. The reason this String doesn't live in HlmsDatablock is to prevent cache trashing (datablocks are hot iterated every frame, and the filename & resource groups are rarely ever used) Usage: String const *filename; String const *resourceGroup; datablock->getFilenameAndResourceGroup( &filename, &resourceGroup ); if( filename && resourceGroup && !filename->empty() && !resourceGroup->empty() ) { //Valid filename & resource group. }

		const HlmsCache &	passCache,
		const QueuedRenderable &	queuedRenderable,
		bool	casterPass
	)

inherited

Retrieves an HlmsCache filled with the GPU programs to be used by the given renderable.

If the shaders have already been created (i.e. whether for this renderable, or another one) it gets them from a cache. Otherwise we create it. It assumes that renderable->setHlms( this, parameters ) has already called.

Parameters

lastReturnedValue	The last value returned by getMaterial.
passCache	The cache returned by .
renderable	The renderable the caller wants us to give the shaders.
movableObject	The MovableObject owner of the renderable (we need it to know if renderable should cast shadows)
casterPass	True if this pass is the shadow mapping caster pass, false otherwise

Returns: Structure containing all necessary shaders

inlineinherited

◆ getNameStr()

const String* Ogre::Hlms::getNameStr ( IdString name ) const

inherited

Returns the string name associated with its hashed name (this was passed as refName in ).

Returns null ptr if not found. The reason this String doesn't live in HlmsDatablock is to prevent cache trashing (datablocks are hot iterated every frame, and the full name is rarely ever used)

		SceneManager *	sceneManager
	)

virtual

Called every frame by the Render Queue to cache the properties needed by this pass.

i.e. Number of PSSM splits, number of shadow casting lights, etc

Parameters

shadowNode The shadow node currently in effect. Can be null.

Returns: A hash and cached property parameters. Unlike , the cache must be kept by the caller and not by us (because it may change every frame and is one for the whole pass, but Mesh' properties usually stay consistent through its lifetime but may differ per mesh)

Reimplemented from Ogre::HlmsBufferManager.

◆ releaseSlot()

void Ogre::ConstBufferPool::releaseSlot ( ConstBufferPoolUser * user )

inherited

Releases a slot requested with requestSlot.

◆ reloadFrom()

virtual void Ogre::Hlms::reloadFrom	(	Archive *	newDataFolder,
		ArchiveVec *	libraryFolders = `0`
	)

virtualinherited

Destroys all the cached shaders and in the next opportunity will recreate them from the new location.

This is very useful for fast iteration and real-time editing of Hlms shader templates.

Remarks: Calling with null pointer is possible and will only invalidate existing shaders but you should provide a valid pointer before we start generating the first shader (or else crash).

: Existing datablock materials won't be reloaded from files, so their properties won't change (i.e. changed from blue to red), but the shaders will.

Parameters

libraryFolders When null pointer, the library folders paths won't be changed at all (but still will be reloaded). When non-null pointer, the library folders will be overwriten. Pass an empty container if you want to stop using libraries.

Reimplemented in Ogre::HlmsCompute.

◆ requestSlot()

void Ogre::ConstBufferPool::requestSlot	(	uint32	hash,
		ConstBufferPoolUser *	user,
		bool	wantsExtraBuffer
	)

inherited

Requests a slot and fills 'user'. Automatically schedules for update.

◆ saveAllTexturesFromDatablocks()

		set< String >::type &	savedTextures,
		bool	saveOitd,

	)

inherited

◆ scheduleForUpdate()

void Ogre::ConstBufferPool::scheduleForUpdate	(	ConstBufferPoolUser *	dirtyUser,
		uint8	dirtyFlags = `DirtyConstBuffer`
	)

inherited

◆ setAreaLightForwardSettings()

void Ogre::Hlms::setAreaLightForwardSettings	(	uint16	areaLightsApproxLimit,
		uint16	areaLightsLtcLimit
	)

inherited

Area lights use regular Forward.

Parameters

areaLightsApproxLimit Maximum number of area approx lights that will be considered by the shader. Default value is 1. Use 0 to disable area lights.

Note: There is little to no performance impact for setting this value higher than you need. e.g. If you set areaLightsApproxLimit = 4, but you only have 2 area lights on scene, you'll pay the price of 2 area lights (but the RAM price of 4).

Beware of setting this value too high (e.g. 65535) as the amount of memory space is limited (we cannot exceed 64kb, including unrelated data to lighting, but required to the pass)

Parameters

areaLightsLtcLimit Same as areaLightsApproxLimit, but for LTC lights

◆ setDebugOutputPath()

void Ogre::Hlms::setDebugOutputPath	(	bool	enableDebugOutput,
		bool	outputProperties,
		const String &	path = `BLANKSTRING`
	)

inherited

Call to output the automatically generated shaders (which are usually made from templates) on the given folder for inspection, analyzing, debugging, etc.

Remarks: The shader will be dumped when it is generated, not when this function gets called. You should call this function at start up

Parameters

enableDebugOutput	Whether to enable or disable dumping the shaders into a folder
outputProperties	Whether to dump properties and pieces at the beginning of the shader file. This is very useful for determining what caused Ogre to compile a new variation. Note that this setting may not always produce valid shader code in the dumped files (but it we'll still produce valid shader code while at runtime) If you want to compile the dumped file and it is invalid, just strip this info.
path	Path location on where to dump it. Should end with slash for proper concatenation (i.e. C:/path/ instead of C:/path; or /home/user/ instead of /home/user)

◆ setEsmK()

void Ogre::HlmsUnlit::setEsmK ( uint16 K )

Sets the 'K' parameter of ESM filter.

Defaults to 600. Small values will give weak shadows, and light bleeding (specially if the caster is close to the receiver; particularly noticeable at contact points). It also gives the chance of over darkening to appear (the shadow of a small caster in front of a large caster looks darker; thus the large caster appers like if it were made of glass instead of being solid).

Large values give strong, dark shadows; but the higher the value, the more you push floating point limits. This value is related to K in MiscUtils::setGaussianLogFilterParams. You don't have to set them to the same value; but you'll notice that if you change this value here, you'll likely have to change the log filter's too.

Parameters

K	In range (0; infinite).

◆ setHighQuality()

void Ogre::Hlms::setHighQuality ( bool highQuality )

inherited

Sets the quality of the Hlms.

This function is most relevant for mobile and almost or completely ignored by Desktop. The default value is false.

: On mobile, high quality will use "highp" quality precision qualifier for all its variables and functions. When not in HQ, mobile users may see aliasing artifacts, gradients; but the performance impact can be quite high. Some GPU drivers might even refuse to execute the shader as they cannot handle it.

: Unless you absolutely require high quality rendering on Mobile devices and/or to get it to look as closely as possible as it looks in a Desktop device, the recommended option is to have this off.

◆ setListener()

void Ogre::Hlms::setListener ( HlmsListener * listener )

inherited

Sets a listener to extend an existing Hlms implementation's with custom code, without having to rewrite it or modify the source code directly.

Remarks: Other alternatives for extending an existing implementation is to derive from the class and override particular virtual functions. For performance reasons, listeners are never called on a per-object basis. Consult the section "Customizing an existing implementation" from the manual in the Docs/2.0 folder.

Parameters

listener Listener pointer. Use null to disable.

◆ setMaxNonCasterDirectionalLights()

void Ogre::Hlms::setMaxNonCasterDirectionalLights ( uint16 maxLights )

inherited

Non-caster directional lights are hardcoded into shaders.

This means that if you have 6 directional lights and then you add a 7th one, a whole new set of shaders will be created.

This setting allows you to tremendously reduce the amount of shader permutations by forcing Ogre to switching to static branching with an upper limit to the max number of non-shadow-casting directional lights.

There is no such switch for shadow-casting directional/point/spot lights because of technical limitations at the GPU level (cannot index shadow map textures in DX11, nor samplers in any known GPU).

See also: setAreaLightForwardSettings

Parameters

maxLights Maximum number of non-caster directional lights. 0 to allow unlimited number of lights, at the cost of shader recompilations when directional lights are added or removed.

Default value is 0.

Note: There is little to no performance impact for setting this value higher than you need. e.g. If you set maxLights = 4, but you only have 2 non-caster dir. lights on scene, you'll pay the price of 2 lights (but the RAM price of 4).

Beware of setting this value too high (e.g. 65535) as the amount of memory space is limited (we cannot exceed 64kb, including unrelated data to lighting, but required to the pass)

◆ setOptimizationStrategy()

virtual void Ogre::HlmsUnlit::setOptimizationStrategy ( OptimizationStrategy optimizationStrategy )

inlinevirtual

Not supported.

Reimplemented from Ogre::ConstBufferPool.

◆ setProperty()

static void Ogre::Hlms::setProperty	(	HlmsPropertyVec &	properties,
		IdString	key,
		int32	value
	)

staticinherited

Utility helper, mostly useful to HlmsListener implementations.

◆ setShadowSettings()

void Ogre::HlmsUnlit::setShadowSettings ( bool useExponentialShadowMaps )

◆ setTextureBufferDefaultSize()

void Ogre::HlmsBufferManager::setTextureBufferDefaultSize ( size_t defaultSize )

inherited

Changes the default suggested size for the texture buffer.

Actual size may be lower if the GPU can't honour the request.
