◆ clone()

VertexArrayObject* Ogre::VertexArrayObject::clone	(	VaoManager *	vaoManager,
		SharedVertexBufferMap *	sharedBuffers,
		int	vertexBufferType = `-1`,
		int	indexBufferType = `-1`
	)		const

inherited

Clones the vertex & index buffers and creates a new VertexArrayObject.

The only exception is when one of the vertex buffers is already in sharedBuffers, in which case the buffer in sharedBuffers.find(vertexBuffer)->second will be used without cloning (useful for cloning LODs).

Parameters

vaoManager	The VaoManager needed to create the structures
sharedBuffers	[in/out] Maps old vertex buffers to new vertex buffers so that we can reuse them. Optional. Use a null pointer to disable this feature.
vertexBufferType	See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.
indexBufferType	See BufferType. Must be set to a valid BufferType. Pass a negative value to keep the same type of the original buffer being cloned.

Returns: New cloned Vao.

◆ findBySemantic()

const VertexElement2* Ogre::VertexArrayObject::findBySemantic	(	VertexElementSemantic	semantic,
		size_t &	outIndex,
		size_t &	outOffset,
		size_t	repeat = `0`
	)		const

inherited

Returns the entire VertexElement2 descriptor in the vertex buffers.

Parameters

semantic	Semantic to look for.
outIndex	The index to mVertexBuffers[index] if it's found. Otherwise the value is left untouched.
outIndex	The offset in bytes to retrieve the element in the vertex data. If the semantic isn't found, the value is left untouched.
repeat	The number of times to skip a semantic before returning the hit. Useful when you have more than one VES_TEXTURE_COORDINATES for example. Set repeat = 0 to retrieve the first set of VES_TEXTURE_COORDINATES Set repeat = 1 to retrieve the second set of VES_TEXTURE_COORDINATES etc.

Returns: Null if not found. The returned pointer might be invalidated by future calls (e.g. something happens to the vertex buffer or the Vao) although this is strange since in general these objects are immutable once they've been constructed.

◆ readRequests()

void Ogre::VertexArrayObject::readRequests	(	ReadRequestsArray &	requests,
		size_t	elementStart = `0`,
		size_t	elementCount = `0`,
		bool	skipRequestIfBufferHasShadowCopy = `false`
	)

inherited

Utility to get multiple pointers & read specific elements of the vertex, even if they're in separate buffers.

When two elements share the same buffer, only one ticket is created.

Example usage: VertexArrayObject::ReadRequestsArray requests; requests.push_back( VertexArrayObject::ReadRequests( VES_POSITION ) ); requests.push_back( VertexArrayObject::ReadRequests( VES_NORMALS ) ); vao->readRequests( requests ); vao->mapAsyncTickets( requests );

for( size_t i=0; i<numVertices; ++i ) { float const position = reinterpret_cast<const float>( requests[0].data ); float const normals = reinterpret_cast<const float>( requests[1].data );

requests[0].data += requests[0].vertexBuffer->getBytesPerElement(); requests[1].data += requests[1].vertexBuffer->getBytesPerElement(); }

vao->unmapAsyncTickets( requests );

Remarks: Throws if an element couldn't be found.

Parameters

requests	[in/out] Array filled with the semantic.
skipRequestIfBufferHasShadowCopy	Avoid generating the AsyncTicket if the buffer has a shadow copy. Useful if you want to read directly from the shadow copy instead of downloading from the GPU. The 'data' variable will be filled immediately if there's a shadow copy available, and mapAsyncTickets can be safely called even if skipRequestIfBufferHasShadowCopy=true

◆ setPrimitiveRange()

void Ogre::VertexArrayObject::setPrimitiveRange	(	uint32	primStart,
		uint32	primCount
	)

inherited

Limits the range of triangle primitives that is rendered.

For VAOs with index buffers, this controls the index start & count, akin to indexStart & indexCount from the v1 objects.

: For VAOs with no index buffers, this controls the vertex start & count, akin to vertexStart & vertexCount from the v1 objects.

Remarks: An exception is thrown if primStart, or primStart + primCount are out of the half open range: [0; mIndexBuffer->getNumElements()) or [0; mVertexBuffers[0]->getNumElements())

: Parameters are always in elements (indices or vertices)

◆ unmapAsyncTickets()

static void Ogre::VertexArrayObject::unmapAsyncTickets ( ReadRequestsArray & tickets )

staticinherited

Unmaps the buffers mapped via.
