Detailed Description

Class for managing Material settings for Ogre.

Remarks
Materials control the eventual surface rendering properties of geometry. This class manages the library of materials, dealing with programmatic registrations and lookups, as well as loading predefined Material settings from scripts.
When loaded from a script, a Material is in an 'unloaded' state and only stores the settings required. It does not at that stage load any textures. This is because the material settings may be loaded 'en masse' from bulk material script files, but only a subset will actually be required.
Because this is a subclass of ResourceManager, any files loaded will be searched for in any path or archive added to the resource paths/archives. See ResourceManager for details.
For a definition of the material script format, see the Tutorials/MaterialScript.html file.

Constructor & Destructor Documentation

◆ MaterialManager()

Ogre::MaterialManager::MaterialManager ( )

Default constructor.

◆ ~MaterialManager()

Ogre::MaterialManager::~MaterialManager ( )
override

Default destructor.

Member Function Documentation

◆ _arbitrateMissingTechniqueForActiveScheme()

virtual Technique* Ogre::MaterialManager::_arbitrateMissingTechniqueForActiveScheme ( Material mat,
unsigned short  lodIndex,
const Renderable rend 
)
virtual

Internal method for sorting out missing technique for a scheme.

◆ _getActiveSchemeIndex()

virtual unsigned short Ogre::MaterialManager::_getActiveSchemeIndex ( ) const
virtual

Internal method - returns the active scheme index.

See also
Technique::setSchemeName

◆ _getSchemeIndex()

virtual unsigned short Ogre::MaterialManager::_getSchemeIndex ( const String name)
virtual

Internal method - returns index for a given material scheme name.

See also
Technique::setSchemeName

◆ _getSchemeName()

virtual const String& Ogre::MaterialManager::_getSchemeName ( unsigned short  index)
virtual

Internal method - returns name for a given material scheme index.

See also
Technique::setSchemeName

◆ _notifyAfterIlluminationPassesCreated()

virtual void Ogre::MaterialManager::_notifyAfterIlluminationPassesCreated ( Technique mat)
virtual

Internal method for sorting out illumination passes for a scheme.

◆ _notifyBeforeIlluminationPassesCleared()

virtual void Ogre::MaterialManager::_notifyBeforeIlluminationPassesCleared ( Technique mat)
virtual

Internal method for sorting out illumination passes for a scheme.

◆ addListener()

virtual void Ogre::MaterialManager::addListener ( Listener l,
const Ogre::String schemeName = BLANKSTRING 
)
virtual

Add a listener to handle material events.

If schemeName is supplied, the listener will only receive events for that certain scheme.

◆ create()

MaterialPtr Ogre::MaterialManager::create ( const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList createParams = 0 
)

Create a new material.

See also
ResourceManager::createResource

◆ getActiveScheme()

virtual const String& Ogre::MaterialManager::getActiveScheme ( ) const
virtual

Returns the name of the active material scheme.

See also
Technique::setSchemeName

◆ getByName()

MaterialPtr Ogre::MaterialManager::getByName ( const String name,
const String groupName = ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME 
)

Get a resource by name.

See also
ResourceManager::getResourceByName

◆ getDefaultSettings()

virtual MaterialPtr Ogre::MaterialManager::getDefaultSettings ( ) const
inlinevirtual

Returns a pointer to the default Material settings.

Remarks
Ogre comes configured with a set of defaults for newly created materials. If you wish to have a different set of defaults, simply call this method and change the returned Material's settings. All materials created from then on will be configured with the new defaults you have specified.
The default settings begin as a single Technique with a single, non-programmable Pass:
  • ambient = ColourValue::White
  • diffuse = ColourValue::White
  • specular = ColourValue::Black
  • emmissive = ColourValue::Black
  • shininess = 0
  • No texture unit settings (& hence no textures)
  • SourceBlendFactor = SBF_ONE
  • DestBlendFactor = SBF_ZERO (no blend, replace with new colour)
  • Depth buffer checking on
  • Depth buffer writing on
  • Depth buffer comparison function = CMPF_LESS_EQUAL
  • Colour buffer writing on for all channels
  • Culling mode = CULL_CLOCKWISE
  • Ambient lighting = ColourValue(0.5, 0.5, 0.5) (mid-grey)
  • Dynamic lighting enabled
  • Gourad shading mode
  • Bilinear texture filtering

◆ getSingleton()

static MaterialManager& Ogre::MaterialManager::getSingleton ( )
static

Override standard Singleton retrieval.

Remarks
Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.
This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

◆ getSingletonPtr()

static MaterialManager* Ogre::MaterialManager::getSingletonPtr ( )
static

Override standard Singleton retrieval.

◆ initialise()

void Ogre::MaterialManager::initialise ( )

Initialises the material manager, which also triggers it to parse all available .program and .material scripts.

◆ parseScript()

void Ogre::MaterialManager::parseScript ( DataStreamPtr stream,
const String groupName 
)
overridevirtual

◆ removeListener()

virtual void Ogre::MaterialManager::removeListener ( Listener l,
const Ogre::String schemeName = BLANKSTRING 
)
virtual

Remove a listener handling material events.

If the listener was added with a custom scheme name, it needs to be supplied here as well.

◆ setActiveScheme()

virtual void Ogre::MaterialManager::setActiveScheme ( const String schemeName)
virtual

Sets the name of the active material scheme.

Technique::setSchemeName

◆ DEFAULT_SCHEME_NAME

String Ogre::MaterialManager::DEFAULT_SCHEME_NAME
static

Default material scheme.
