Member Typedef Documentation

◆ VertexElementList

typedef list<VertexElement>::type Ogre::VertexDeclaration::VertexElementList

inherited

Defines the list of vertex elements that makes up this declaration.

Definition at line 341 of file OgreHardwareVertexBuffer.h.

Constructor & Destructor Documentation

◆ GLES2VertexDeclaration()

Ogre::GLES2VertexDeclaration::GLES2VertexDeclaration ( )

◆ ~GLES2VertexDeclaration()

Ogre::GLES2VertexDeclaration::~GLES2VertexDeclaration ( )

Member Function Documentation

◆ addElement()

virtual const VertexElement& Ogre::VertexDeclaration::addElement	(	unsigned short	source,
		size_t	offset,
		VertexElementType	theType,
		VertexElementSemantic	semantic,
		unsigned short	index = `0`
	)

virtualinherited

Adds a new VertexElement to this declaration.

Remarks: This method adds a single element (positions, normals etc) to the end of the vertex declaration. Please read the information in VertexDeclaration about the importance of ordering and structure for compatibility with older D3D drivers.

Parameters

source	The binding index of HardwareVertexBuffer which will provide the source for this element. See VertexBufferBinding for full information.
offset	The offset in bytes where this element is located in the buffer
theType	The data format of the element (3 floats, a colour etc)
semantic	The meaning of the data (position, normal, diffuse colour etc)
index	Optional index for multi-input elements like texture coordinates

Returns: A reference to the VertexElement added.

Reimplemented in Ogre::D3D11VertexDeclaration, and Ogre::D3D9VertexDeclaration.

◆ bind()

void Ogre::GLES2VertexDeclaration::bind ( void )

◆ clone()

virtual VertexDeclaration* Ogre::VertexDeclaration::clone ( HardwareBufferManagerBase * mgr = 0 ) const

virtualinherited

Clones this declaration.

Parameters

mgr	Optional HardwareBufferManager to use for creating the clone (if null, use the current default).

◆ closeGapsInSource()

void Ogre::VertexDeclaration::closeGapsInSource ( void )

inherited

Remove any gaps in the source buffer list used by this declaration.

Remarks: This is useful if you've modified a declaration and want to remove any gaps in the list of buffers being used. Note, however, that if this declaration is already being used with a VertexBufferBinding, you will need to alter that too. This method is mainly useful when reorganising buffers based on an altered declaration.

Note: This will cause the vertex declaration to be re-sorted.

◆ findElementBySemantic()

virtual const VertexElement* Ogre::VertexDeclaration::findElementBySemantic	(	VertexElementSemantic	sem,
		unsigned short	index = `0`
	)		const

virtualinherited

Finds a VertexElement with the given semantic, and index if there is more than one element with the same semantic.

Remarks: If the element is not found, this method returns null.

◆ findElementsBySource()

virtual VertexElementList Ogre::VertexDeclaration::findElementsBySource ( unsigned short source ) const

virtualinherited

Based on the current elements, gets the size of the vertex for a given buffer source.

Parameters

source The buffer binding index for which to get the vertex size.Gets a list of elements which use a given source.

Remarks: Note that the list of elements is returned by value therefore is separate from the declaration as soon as this method returns.

◆ getAutoOrganisedDeclaration()

VertexDeclaration* Ogre::VertexDeclaration::getAutoOrganisedDeclaration	(	bool	skeletalAnimation,
		bool	vertexAnimation,
		bool	vertexAnimationNormals
	)		const

inherited

Generates a new VertexDeclaration for optimal usage based on the current vertex declaration, which can be used with VertexData::reorganiseBuffers later if you wish, or simply used as a template.

Remarks: Different buffer organisations and buffer usages will be returned depending on the parameters passed to this method.

Parameters

skeletalAnimation	Whether this vertex data is going to be skeletally animated
vertexAnimation	Whether this vertex data is going to be vertex animated
vertexAnimationNormals	Whether vertex data animation is going to include normals animation

◆ getElement()

const VertexElement* Ogre::VertexDeclaration::getElement ( unsigned short index ) const

inherited

Get a single element.

◆ getElementCount()

size_t Ogre::VertexDeclaration::getElementCount ( void ) const

inherited

Get the number of elements in the declaration.

Definition at line 352 of file OgreHardwareVertexBuffer.h.

◆ getElements()

const VertexElementList& Ogre::VertexDeclaration::getElements ( void ) const

inherited

Gets read-only access to the list of vertex elements.

◆ getMaxSource()

unsigned short Ogre::VertexDeclaration::getMaxSource ( void ) const

inherited

Gets the index of the highest source value referenced by this declaration.

◆ getNextFreeTextureCoordinate()

virtual unsigned short Ogre::VertexDeclaration::getNextFreeTextureCoordinate ( ) const

virtualinherited

Return the index of the next free texture coordinate set which may be added to this declaration.

◆ getVertexSize()

virtual size_t Ogre::VertexDeclaration::getVertexSize ( unsigned short source ) const

virtualinherited

Gets the vertex size defined by this declaration for a given source.

◆ insertElement()

virtual const VertexElement& Ogre::VertexDeclaration::insertElement	(	unsigned short	atPosition,
		unsigned short	source,
		size_t	offset,
		VertexElementType	theType,
		VertexElementSemantic	semantic,
		unsigned short	index = `0`
	)

virtualinherited

Inserts a new VertexElement at a given position in this declaration.

Remarks: This method adds a single element (positions, normals etc) at a given position in this vertex declaration. Please read the information in VertexDeclaration about the importance of ordering and structure for compatibility with older D3D drivers.

Parameters

source	The binding index of HardwareVertexBuffer which will provide the source for this element. See VertexBufferBinding for full information.
offset	The offset in bytes where this element is located in the buffer
theType	The data format of the element (3 floats, a colour etc)
semantic	The meaning of the data (position, normal, diffuse colour etc)
index	Optional index for multi-input elements like texture coordinates

Returns: A reference to the VertexElement added.

Reimplemented in Ogre::D3D11VertexDeclaration, and Ogre::D3D9VertexDeclaration.

Remarks: Older graphics cards require vertex data to be presented in a more rigid way, as defined in the main documentation for this class. As well as the ordering being important, where shared source buffers are used, the declaration must list all the elements for each source in turn.
