## Detailed Description

Class encapsulates rendering properties of an object.

Remarks
  Ogre's material class encapsulates ALL aspects of the visual appearance, of an object. It also includes other flags which might not be traditionally thought of as material properties such as culling modes and depth buffer settings, but these affect the appearance of the rendered object and are convenient to attach to the material since it keeps all the settings in one place. This is different to Direct3D which treats a material as just the colour components (diffuse, specular) and not texture maps etc. An Ogre Material can be thought of as equivalent to a 'Shader'.

  A Material can be rendered in multiple different ways depending on the hardware available. You may configure a Material to use high-complexity fragment shaders, but these won't work on every card; therefore a Technique is an approach to creating the visual effect you are looking for. You are advised to create fallback techniques with lower hardware requirements if you decide to use advanced features. In addition, you also might want lower-detail techniques for distant geometry.

  Each technique can be made up of multiple passes. A fixed-function pass may combine multiple texture layers using multitexturing, but Ogre can break that into multiple passes automatically if the active card cannot handle that many simultaneous textures. Programmable passes, however, cannot be split down automatically, so if the active graphics card cannot handle the technique which contains these passes, OGRE will try to find another technique which the card can do. If, at the end of the day, the card cannot handle any of the techniques which are listed for the material, the engine will render the geometry plain white, which should alert you to the problem.

  Ogre comes configured with a number of default settings for a newly created material. These can be changed if you wish by retrieving the default material settings through SceneManager::getDefaultMaterialSettings. Any changes you make to the Material returned from this method will apply to any materials created from this point onward.

## Constructor & Destructor Documentation

## ◆ Material()

Ogre::Material::Material | ( | ResourceManager * | creator,
|  | const String & | name,
|  | ResourceHandle | handle,
|  | const String & | group,
|  | bool | isManual = `false`,
|  | ManualResourceLoader * | loader = `0`
| ) |  |

Constructor - use resource manager's create method rather than this.

## ◆ ~Material()

Ogre::Material::~Material | ( |  | ) |

## Member Function Documentation

## ◆ _dirtyState()

virtual void Ogre::Resource::_dirtyState | ( |  | ) |
| virtualinherited

Manually mark the state of this resource as having been changed.

Remarks
  You only need to call this from outside if you explicitly want derived objects to think this object has changed.

See also
  getStateCount.

## ◆ _fireLoadingComplete()

virtual void Ogre::Resource::_fireLoadingComplete | ( | bool | wasBackgroundLoaded | ) |
| virtualinherited

Firing of loading complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

  wasBackgroundLoaded | Whether this was a background loaded event

## ◆ _firePreparingComplete()

virtual void Ogre::Resource::_firePreparingComplete | ( | bool | wasBackgroundLoaded | ) |
| virtualinherited

Firing of preparing complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters

  wasBackgroundLoaded | Whether this was a background loaded event

## ◆ _fireUnloadingComplete()

virtual void Ogre::Resource::_fireUnloadingComplete | ( | void |  | ) |
| virtualinherited

Firing of unloading complete event.

Remarks
  You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

## ◆ _getLodValues()

const LodValueArray* Ogre::Material::_getLodValues | ( | void |  | ) | const
| inline

## ◆ _notifyNeedsRecompile()

void Ogre::Material::_notifyNeedsRecompile | ( | void |  | ) |

Tells the material that it needs recompilation.

## ◆ _notifyOrigin()

virtual void Ogre::Resource::_notifyOrigin | ( | const String & | origin | ) |
| inlinevirtualinherited

Notify this resource of it's origin.

## ◆ addListener()

virtual void Ogre::Resource::addListener | ( | Listener * | lis | ) |
| virtualinherited

Register a listener on this resource.

See also
  Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ applyTextureAliases()

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

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

All techniques, passes, and Texture Unit States within the material 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 material.

## ◆ changeGroupOwnership()

virtual void Ogre::Resource::changeGroupOwnership | ( | const String & | newGroup | ) |
| virtualinherited

Change the resource group ownership of a Resource.

Remarks
  This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters

  newGroup | Name of the new group

## ◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary | ( |  | ) |
| staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

## ◆ clone()

MaterialPtr Ogre::Material::clone | ( | const String & | newName,
|  | bool | changeGroup = `false`,
|  | const String & | newGroup = `BLANKSTRING`
| ) |  | const

Creates a new copy of this material with the same settings but a new name.

Parameters

  newName | The name for the cloned material
  changeGroup | If true, the resource group of the clone is changed
  newGroup | Only required if changeGroup is true; the new group to assign

## ◆ compile()

void Ogre::Material::compile | ( | bool | autoManageTextureUnits = `true` | ) |

'Compiles' this Material.

Remarks
  Compiling a material involves determining which Techniques are supported on the card on which OGRE is currently running, and for fixed-function Passes within those Techniques, splitting the passes down where they contain more TextureUnitState instances than the current card has texture units.

  This process is automatically done when the Material is loaded, but may be repeated if you make some procedural changes.

Parameters

  autoManageTextureUnits | If true, when a fixed function pass has too many TextureUnitState entries than the card has texture units, the Pass in question will be split into more than one Pass in order to emulate the Pass. If you set this to false and this situation arises, an Exception will be thrown.

## ◆ copyDetailsTo()

void Ogre::Material::copyDetailsTo | ( | MaterialPtr & | mat | ) | const

Copies the details of this material into another, preserving the target's handle and name (unlike operator=) but copying everything else.

Parameters

  mat | Weak reference to material which will receive this material's settings.

## ◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo | ( | StringInterface * | dest | ) | const
| inlinevirtualinherited

Method for copying this object's parameters to another object.

Remarks
  This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

  Any unrecognised parameters will be ignored as with setParameter method.

Parameters

  dest | Pointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

## ◆ createTechnique()

Technique* Ogre::Material::createTechnique | ( | void |  | ) |

Creates a new Technique for this Material.

Remarks
  A Technique is a single way of rendering geometry in order to achieve the effect you are intending in a material. There are many reason why you would want more than one - the main one being to handle variable graphics card abilities; you might have one technique which is impressive but only runs on 4th-generation graphics cards, for example. In this case you will want to create at least one fallback Technique. OGRE will work out which Techniques a card can support and pick the best one.

  If multiple Techniques are available, the order in which they are created is important - the engine will consider lower-indexed Techniques to be preferable to higher-indexed Techniques, ie when asked for the 'best' technique it will return the first one in the technique list which is supported by the hardware.

## ◆ escalateLoading()

virtual void Ogre::Resource::escalateLoading | ( |  | ) |
| virtualinherited

Escalates the loading of a background loaded resource.

Remarks
  If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ getBestTechnique()

Technique* Ogre::Material::getBestTechnique | ( | unsigned short | lodIndex = `0`,
|  | const Renderable * | rend = `0`
| ) |  |

Gets the best supported technique.

Remarks
  This method returns the lowest-index supported Technique in this material (since lower-indexed Techniques are considered to be better than higher-indexed ones).

  The best supported technique is only available after this material has been compiled, which typically happens on loading the material. Therefore, if this method returns NULL, try calling Material::load.

Parameters

  lodIndex | The material LOD index to use
  rend | Optional parameter specifying the Renderable that is requesting this technique. Only used if no valid technique for the active material scheme is found, at which point it is passed to MaterialManager::Listener::handleSchemeNotFound as information.

## ◆ getCompilationRequired()

bool Ogre::Material::getCompilationRequired | ( |  | ) | const
| inline

Gets the compilation status of the material.

Returns
  True if the material needs recompilation.

## ◆ getCreator()

virtual ResourceManager* Ogre::Resource::getCreator | ( | void |  | ) |
| inlinevirtualinherited

Gets the manager which created this resource.

## ◆ getGroup()

virtual const String& Ogre::Resource::getGroup | ( | void |  | ) | const
| inlinevirtualinherited

Gets the group which this resource is a member of.

Reimplemented in Ogre::v1::OldSkeletonInstance.

## ◆ getHandle()

virtual ResourceHandle Ogre::Resource::getHandle | ( | void |  | ) | const
| inlinevirtualinherited

Reimplemented in Ogre::v1::OldSkeletonInstance.

## ◆ getLoadingState()

virtual LoadingState Ogre::Resource::getLoadingState | ( |  | ) | const
| inlinevirtualinherited

Returns the current loading state.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::get().

## ◆ getLodValueIterator()

LodValueIterator Ogre::Material::getLodValueIterator | ( | void |  | ) | const

Gets an iterator over the list of values transformed by the LodStrategy at which each LOD comes into effect.

Remarks
  Note that the iterator returned from this method is not totally analogous to the one passed in by calling setLodLevels - the list includes a zero entry at the start (since the highest LOD starts at value 0). Also, the values returned are after being transformed by LodStrategy::transformUserValue.

## ◆ getName()

virtual const String& Ogre::Resource::getName | ( | void |  | ) | const
| inlinevirtualinherited

Gets resource name.

Reimplemented in Ogre::v1::OldSkeletonInstance.

Referenced by Ogre::GpuProgramUsage::getProgramName().

## ◆ getNumLodLevels() [1/2]

unsigned short Ogre::Material::getNumLodLevels | ( | const String & | schemeName | ) | const

Gets the number of levels-of-detail this material has in the given scheme, based on Technique::setLodIndex.

Remarks
  Note that this will not be up to date until the material has been compiled.

## ◆ getNumLodLevels() [2/2]

unsigned short Ogre::Material::getNumLodLevels | ( | unsigned short | schemeIndex | ) | const

Gets the number of levels-of-detail this material has in the given scheme, based on Technique::setLodIndex.

Remarks
  Note that this will not be up to date until the material has been compiled.

## ◆ getNumSupportedTechniques()

unsigned short Ogre::Material::getNumSupportedTechniques | ( | void |  | ) | const

Retrieves the number of supported techniques.

## ◆ getNumTechniques()

unsigned short Ogre::Material::getNumTechniques | ( | void |  | ) | const

Retrieves the number of techniques.

## ◆ getOrigin()

virtual const String& Ogre::Resource::getOrigin | ( | void |  | ) | const
| inlinevirtualinherited

Get the origin of this resource, e.g.

a script file name.

Remarks
  This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

## ◆ getParamDictionary() [1/2]

ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) |
| inlineinherited

Retrieves the parameter dictionary for this class.

Remarks
  Only valid to call this after createParamDictionary.

Returns
  Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

## ◆ getParamDictionary() [2/2]

const ParamDictionary* Ogre::StringInterface::getParamDictionary | ( | void |  | ) | const
| inlineinherited

## ◆ getParameter()

virtual String Ogre::StringInterface::getParameter | ( | const String & | name | ) | const
| inlinevirtualinherited

Generic parameter retrieval method.

Remarks
  Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters

  name | The name of the parameter to get

Returns
  String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

## ◆ getParameters()

const ParameterList& Ogre::StringInterface::getParameters | ( | void |  | ) | const
| inherited

Retrieves a list of parameters valid for this object.

Returns
  A reference to a static list of ParameterDef objects.

## ◆ getReceiveShadows()

bool Ogre::Material::getReceiveShadows | ( | void |  | ) | const
| inline

Returns whether or not objects using this material will receive shadows.

## ◆ getSize()

virtual size_t Ogre::Resource::getSize | ( | void |  | ) | const
| inlinevirtualinherited

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ getStateCount()

virtual size_t Ogre::Resource::getStateCount | ( |  | ) | const
| inlinevirtualinherited

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

## ◆ getSupportedTechnique()

Technique* Ogre::Material::getSupportedTechnique | ( | unsigned short | index | ) |

Gets the indexed supported technique.

## ◆ getSupportedTechniqueIterator()

TechniqueIterator Ogre::Material::getSupportedTechniqueIterator | ( | void |  | ) |

Gets an iterator over all the Techniques which are supported by the current card.

Remarks
  The supported technique list is only available after this material has been compiled, which typically happens on loading the material. Therefore, if this method returns an empty list, try calling Material::load.

## ◆ getTechnique() [1/2]

Technique* Ogre::Material::getTechnique | ( | const String & | name | ) |

searches for the named technique.

Return 0 if technique with name is not found

## ◆ getTechnique() [2/2]

Technique* Ogre::Material::getTechnique | ( | unsigned short | index | ) |

Gets the indexed technique.

## ◆ getTechniqueIterator()

TechniqueIterator Ogre::Material::getTechniqueIterator | ( | void |  | ) |

Get an iterator over the Techniques in this Material.

## ◆ getTransparencyCastsShadows()

bool Ogre::Material::getTransparencyCastsShadows | ( | void |  | ) | const
| inline

Returns whether or not objects using this material be classified as opaque to the shadow caster system.

## ◆ getUnsupportedTechniquesExplanation()

const String& Ogre::Material::getUnsupportedTechniquesExplanation | ( |  | ) | const
| inline

Gets a string explaining why any techniques are not supported.

## ◆ getUserLodValueIterator()

LodValueIterator Ogre::Material::getUserLodValueIterator | ( | void |  | ) | const

Gets an iterator over the user-defined list of values which are internally transfomed by the LodStrategy.

Remarks
  Note that the iterator returned from this method is not totally analogous to the one passed in by calling setLodLevels - the list includes a zero entry at the start (since the highest LOD starts at value 0). Also, the values returned are after being transformed by LodStrategy::transformUserValue.

## ◆ isBackgroundLoaded()

virtual bool Ogre::Resource::isBackgroundLoaded | ( | void |  | ) | const
| inlinevirtualinherited

Returns whether this Resource has been earmarked for background loading.

Remarks
  This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ isLoaded()

virtual bool Ogre::Resource::isLoaded | ( | void |  | ) | const
| inlinevirtualinherited

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

References Ogre::AtomicScalar< T >::get().

## ◆ isLoading()

virtual bool Ogre::Resource::isLoading | ( |  | ) | const
| inlinevirtualinherited

Returns whether the resource is currently in the process of background loading.

| inlinevirtualinherited

Is this resource manually loaded?

## ◆ isPrepared()

virtual bool Ogre::Resource::isPrepared | ( | void |  | ) | const
| inlinevirtualinherited

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ isTransparent()

bool Ogre::Material::isTransparent | ( | void |  | ) | const

Determines if the material has any transparency with the rest of the scene (derived from whether any Techniques say they involve transparency).

## ◆ load()

virtual void Ogre::Resource::load | ( | bool | backgroundThread = `false` | ) |
| virtualinherited

## ◆ operator=()

Material& Ogre::Material::operator= | ( | const Material & | rhs | ) |

Assignment operator to allow easy copying between materials.

## ◆ prepare()

virtual void Ogre::Resource::prepare | ( | bool | backgroundThread = `false` | ) |
| virtualinherited

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters

  backgroundThread | Whether this is occurring in a background thread

## ◆ reload()

virtual void Ogre::Resource::reload | ( | LoadingFlags | flags = `LF_DEFAULT` | ) |
| virtualinherited

## ◆ setAmbient() [1/2]

void Ogre::Material::setAmbient | ( | const ColourValue & | ambient | ) |

Sets the ambient colour reflectance properties for every Pass in every Technique.

Note
  This property has been moved to the Pass class, which is accessible via the Technique.

## ◆ setBackgroundLoaded()

virtual void Ogre::Resource::setBackgroundLoaded | ( | bool | bl | ) |
| inlinevirtualinherited

Tells the resource whether it is background loaded or not.

Remarks

See also
  Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

## ◆ setLodLevels()

void Ogre::Material::setLodLevels | ( | const LodValueArray & | lodValues | ) |

Sets the distance at which level-of-detail (LOD) levels come into effect.

Remarks
  You should only use this if you have assigned LOD indexes to the Technique instances attached to this Material. If you have done so, you should call this method to determine the distance at which the lowe levels of detail kick in. The decision about what distance is actually used is a combination of this and the LOD bias applied to both the current Camera and the current Entity.

Parameters

  lodValues | A vector of Reals which indicate the LOD value at which to switch to lower details. They are listed in LOD index order, starting at index 1 (ie the first level down from the highest level 0, which automatically applies from a value of 0). These are 'user values', before being potentially transformed by the strategy, so for the distance strategy this is an unsquared distance for example.

## ◆ setMacroblock()
