Detailed Description

Mapped buffer is a container for GPU memory that is mapped into CPU memory.

This is a RAII-style object that automatically updates the data to the GPU in the destructor.

Constructor & Destructor Documentation

kanzi::Mesh::MappedBuffer::MappedBuffer	(	Mesh *	mesh,
		GPUBuffer *	buffer,
		size_t	size
	)

explicit

Constructor with buffer handle.

Maps the buffer with the given handle. Unmapping happens in destructor.

Parameters

mesh	Mesh whose buffers are mapped.
buffer	Buffer that is mapped, must belong to the mesh mentioned above.
size	Size of the mapped memory region in bytes.

kanzi::Mesh::MappedBuffer::MappedBuffer ( MappedBuffer && other )

inline

Move constructor.

kanzi::Mesh::MappedBuffer::~MappedBuffer ( )

Destructor that takes care that the GPU data matches the CPU data after it has been run.

MappedBuffer& kanzi::Mesh::MappedBuffer::operator= ( MappedBuffer && other )

inline

Move assignment operator.

template<typename T >

void kanzi::Mesh::MappedBuffer::write	(	const T *	data,
		size_t	startElement,
		size_t	elements
	)

inline

Write data to mapped buffer.

The data will be updated to the GPU in the destructor.

Parameters

data	Data to write to the mapped memory.
startElement	Element number from which start writing the data.
elements	Number of element to write.
