Member Function Documentation

◆ isSupported()

bool Ogre::Technique::isSupported ( void ) const

Indicates if this technique is supported by the current graphics card.

Remarks: This will only be correct after the Technique has been compiled, which is usually done from Material::compile.

◆ _compile()

String Ogre::Technique::_compile ( bool autoManageTextureUnits )

Internal compilation method; see Material::compile.

Returns: Any information explaining problems with the compile.

◆ checkGPURules()

bool Ogre::Technique::checkGPURules ( StringStream & errors )

Internal method for splitting the passes into illumination passes.

◆ calculateSize()

size_t Ogre::Technique::calculateSize ( void ) const

◆ createPass()

Pass* Ogre::Technique::createPass ( void )

Creates a new Pass for this Technique.

Remarks: A Pass is a single rendering pass, i.e. a single draw of the given material. Note that if you create a pass without a fragment program, during compilation of the material the pass may be split into multiple passes if the graphics card cannot handle the number of texture units requested. For passes with fragment programs, however, the number of passes you create will never be altered, so you have to make sure that you create an alternative fallback Technique for if a card does not have enough facilities for what you're asking for.

Pass* Ogre::Technique::getPass ( unsigned short index )

Retrieves the Pass with the given index.

Deprecated:: use getPasses()

◆ getPass() [2/2]

◆ setLodIndex()

void Ogre::Technique::setLodIndex ( unsigned short index )

Assigns a level-of-detail (LOD) index to this Technique.

Remarks: As noted previously, as well as providing fallback support for various graphics cards, multiple Technique objects can also be used to implement material LOD, where the detail of the material diminishes with distance to save rendering power.

: By default, all Techniques have a LOD index of 0, which means they are the highest level of detail. Increasing LOD indexes are lower levels of detail. You can assign more than one Technique to the same LOD index, meaning that the best Technique that is supported at that LOD index is used.

: You should not leave gaps in the LOD sequence; Ogre will allow you to do this and will continue to function as if the LODs were sequential, but it will confuse matters.

◆ getLodIndex()

unsigned short Ogre::Technique::getLodIndex ( void ) const

inline

Gets the level-of-detail index assigned to this Technique.

◆ setSchemeName()

void Ogre::Technique::setSchemeName ( const String & schemeName )

Set the 'scheme name' for this technique.

Remarks: Material schemes are used to control top-level switching from one set of techniques to another. For example, you might use this to define 'high', 'medium' and 'low' complexity levels on materials to allow a user to pick a performance / quality ratio. Another possibility is that you have a fully HDR-enabled pipeline for top machines, rendering all objects using unclamped shaders, and a simpler pipeline for others; this can be implemented using schemes.

: Every technique belongs to a scheme - if you don't specify one, the Technique belongs to the scheme called 'Default', which is also the scheme used to render by default. The active scheme is set one of two ways - either by calling Viewport::setMaterialScheme, or by manually calling MaterialManager::setActiveScheme.

◆ getSchemeName()

const String& Ogre::Technique::getSchemeName ( void ) const

Returns the scheme to which this technique is assigned.

See also: Technique::setSchemeName

◆ _getSchemeIndex()

unsigned short Ogre::Technique::_getSchemeIndex ( void ) const

Remarks: The use of technique name is optional. Its useful in material scripts where a material could inherit from another material and only want to modify a particular technique.

◆ getName()

const String& Ogre::Technique::getName ( void ) const

inline

Gets the name of the technique.

◆ applyTextureAliases()

bool Ogre::Technique::applyTextureAliases	(	const AliasTextureNamePairList &	aliasList,
		const bool	apply = `true`
	)		const

Applies texture names to Texture Unit State with matching texture name aliases.

All passes, and Texture Unit States within the technique are checked. If matching texture aliases are found then true is returned.

Parameters

aliasList	is a map container of texture alias, texture name pairs
apply	set true to apply the texture aliases else just test to see if texture alias matches are found.

Returns: True if matching texture aliases were found in the Technique.

◆ addGPUVendorRule() [1/2]

void Ogre::Technique::addGPUVendorRule	(	GPUVendor	vendor,
		IncludeOrExclude	includeOrExclude
	)

Add a rule which manually influences the support for this technique based on a GPU vendor.

Remarks: You can use this facility to manually control whether a technique is considered supported, based on a GPU vendor. You can add inclusive or exclusive rules, and you can add as many of each as you like. If at least one inclusive rule is added, a technique is considered unsupported if it does not match any of those inclusive rules. If exclusive rules are added, the technique is considered unsupported if it matches any of those inclusive rules.

Note: Any rule for the same vendor will be removed before adding this one.

Parameters

vendor	The GPU vendor
includeOrExclude	Whether this is an inclusive or exclusive rule

◆ addGPUVendorRule() [2/2]

void Ogre::Technique::addGPUVendorRule ( const GPUVendorRule & rule )

Add a rule which manually influences the support for this technique based on a GPU vendor.

Remarks: You can use this facility to manually control whether a technique is considered supported, based on a GPU vendor. You can add inclusive or exclusive rules, and you can add as many of each as you like. If at least one inclusive rule is added, a technique is considered unsupported if it does not match any of those inclusive rules. If exclusive rules are added, the technique is considered unsupported if it matches any of those inclusive rules.

Note: Any rule for the same vendor will be removed before adding this one.

◆ removeGPUVendorRule()

void Ogre::Technique::removeGPUVendorRule ( GPUVendor vendor )

Removes a matching vendor rule.

See also: addGPUVendorRule

◆ getGPUVendorRuleIterator()

GPUVendorRuleIterator Ogre::Technique::getGPUVendorRuleIterator ( ) const

Get an iterator over the currently registered vendor rules.

Deprecated:: use getGPUVendorRules()

◆ getGPUVendorRules()

const GPUVendorRuleList& Ogre::Technique::getGPUVendorRules ( ) const

inline

Get the currently registered vendor rules.

◆ addGPUDeviceNameRule() [1/2]

void Ogre::Technique::addGPUDeviceNameRule	(	const String &	devicePattern,
		IncludeOrExclude	includeOrExclude,
		bool	caseSensitive = `false`
	)

Add a rule which manually influences the support for this technique based on a pattern that matches a GPU device name (e.g.

'8800').

Remarks: You can use this facility to manually control whether a technique is considered supported, based on a GPU device name pattern. You can add inclusive or exclusive rules, and you can add as many of each as you like. If at least one inclusive rule is added, a technique is considered unsupported if it does not match any of those inclusive rules. If exclusive rules are added, the technique is considered unsupported if it matches any of those inclusive rules. The pattern you supply can include wildcard characters ('*') if you only want to match part of the device name.

Note: Any rule for the same device pattern will be removed before adding this one.

Parameters

devicePattern	The GPU vendor
includeOrExclude	Whether this is an inclusive or exclusive rule
caseSensitive	Whether the match is case sensitive or not

◆ addGPUDeviceNameRule() [2/2]

void Ogre::Technique::addGPUDeviceNameRule ( const GPUDeviceNameRule & rule )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ removeGPUDeviceNameRule()

void Ogre::Technique::removeGPUDeviceNameRule ( const String & devicePattern )

Removes a matching device name rule.
